# Honeywell

Honeywell International Inc. is an American publicly traded, multinational conglomerate corporation headquartered in Charlotte, North Carolina. It primarily operates in four areas of business: aerospace, building automation, industrial automation, and energy and sustainability solutions (ESS). Honeywell is a Fortune 500 company, ranked 115th in 2023. In 2024, the corporation had a global workforce of approximately 102,000 employees. As of 2020, the current chairman and chief executive officer is Vimal Kapur.
The corporation's name, Honeywell International Inc., is a product of the merger of Honeywell Inc. and AlliedSignal in 1999. The corporation headquarters were consolidated with AlliedSignal's headquarters in Morristown, New Jersey. The combined company chose the name "Honeywell" because of the considerable brand recognition. Honeywell was a component of the Dow Jones Industrial Average index from 1999 to 2008. Prior to 1999, its corporate predecessors were included dating back to 1925, including early entrants in the computing and thermostat industries.
In 2020, Honeywell rejoined the Dow Jones Industrial Average index. In 2021, it moved its stock listing from the New York Stock Exchange to the Nasdaq.

## History

The Butz Thermo-Electric Regulator Company was founded in 1885 when the Swiss-born Albert Butz invented the damper-flapper, a thermostat used to control coal furnaces, bringing automated heating system regulation into homes. In 1886, he founded the Butz Thermo-Electric Regulator Company. In 1888, after a falling out with his investors, Butz left the company and transferred the patents to the legal firm Paul, Sanford, and Merwin, who renamed the company the Consolidated Temperature Controlling Company.
As the years passed, CTCC struggled with debt, and the company underwent several name changes. After it was renamed the Electric Heat Regulator Company in 1893, W.R. Sweatt, a stockholder in the company, was sold "an extensive list of patents" and named secretary-treasurer.$^{:22}$ By 1900, Sweatt had bought out the remaining shares of the company from the other stockholders.

### 1906 Honeywell Heating Specialty Company founded

In 1906, Mark Honeywell founded the Honeywell Heating Specialty Company in Wabash, Indiana, to manufacture and market his invention, the mercury seal generator.

### 1922–1934 Mergers and acquisitions

As Honeywell's company grew, thanks in part to the acquisition of Jewell Manufacturing Company in 1922 to better automate his heating system, it began to clash with the Electric Heat Regulator Company now-renamed Minneapolis Heat Regulator Company. In 1927, this led to the merging of both companies into the publicly-held Minneapolis-Honeywell Regulator Company. Honeywell was named the company's first president, alongside W.R. Sweatt as its first chairman.
In 1929, combined assets were valued at over $3.5 million, with less than $1 million in liabilities just months before Black Monday.$^{:49}$ In 1931, Minneapolis-Honeywell began a period of expansion and acquisition when they purchased the Time-O-Stat Controls Company, giving the company access to a greater number of patents for their controls systems.
W.R. Sweatt and his son Harold provided 75 years of uninterrupted leadership for the company. W.R. Sweatt survived rough spots and turned an innovative idea – thermostatic heating control – into a thriving business.

### 1934–1941 International growth

Harold took over in 1934, leading Honeywell through a period of growth and global expansion that set the stage for Honeywell to become a global technology leader. The merger into the Minneapolis-Honeywell Regulator Company proved to be a saving grace for the corporation.
1934 marked Minneapolis-Honeywell's first foray into the international market, when they acquired the Brown Instrument Company and inherited their relationship with the Yamatake Company of Tokyo, a Japan-based distributor.$^{:51}$ Later in 1934, Minneapolis-Honeywell started distributorships across Canada, as well as one in the Netherlands, their first European office. This expansion into international markets continued in 1936, with their first distributorship in London, as well as their first foreign assembly facility being established in Canada. By 1937, ten years after the merger, Minneapolis-Honeywell had over 3,000 employees, with $16 million in annual revenue.

### World War II

With the outbreak of World War II, Minneapolis-Honeywell was approached by the US military for engineering and manufacturing projects. In 1941, Minneapolis-Honeywell developed a superior tank periscope, camera stabilizers, and the C-1 autopilot.
The C-1 revolutionized precision bombing and was ultimately used on the two B-29 bombers that dropped atomic bombs on Japan in 1945. The success of these projects led Minneapolis-Honeywell to open an Aero division in Chicago on October 5, 1942.$^{:73}$ This division was responsible for the development of the formation stick to control autopilots, more accurate fuel quantity indicators for aircraft, and the turbo supercharger.$^{:79}$
In 1950, Minneapolis-Honeywell's Aero division was contracted for the controls on the first US nuclear submarine, USS Nautilus.$^{:88}$ In 1951, the company acquired Intervox Company for their sonar, ultrasonic, and telemetry technologies. Honeywell also helped develop and manufacture the RUR-5 ASROC for the US Navy.

### 1950–1970s

In 1953, in cooperation with the USAF Wright-Air Development Center, Honeywell developed an automated control unit, that could control an aircraft through various stages of a flight, from taxiing to takeoff to the point where the aircraft neared its destination and the pilot took over for landing. Called the Automatic Master Sequence Selector, the onboard control operated similarly to a player piano to relay instructions to the aircraft's autopilot at certain way points during the flight, significantly reducing the pilot's workload. Technologically, this effort had parallels to contemporary efforts in missile guidance and numerical control. Honeywell also developed the Wagtail missile with the USAF.
From the 1950s until the mid-1970s, Honeywell was the United States' importer of Japanese company Asahi Optical's Pentax cameras and photographic equipment.$^{:153}$ These products were labeled "Heiland Pentax" and "Honeywell Pentax" in the U.S. In 1953, Honeywell introduced their most famous product, the T-86 Round thermostat.$^{:110}$
In 1961, James H. Binger became Honeywell's president and in 1965 its chairman. Binger revamped the company sales approach, placing emphasis on profits rather than on volume. He stepped up the company's international expansion – it had six plants producing 12% of the company's revenue. He officially changed the company's corporate name from "Minneapolis-Honeywell Regulator Co." to "Honeywell", to better represent their colloquial name. Throughout the 1960s, Honeywell continued to acquire other businesses, including Security Burglar Alarm Company in 1969.$^{:130}$
In the 1970s, after one member of a group called FREE on the Minneapolis campus (U of M) of the University of Minnesota asked five major companies with local offices to explain their attitudes toward gay men and women, three responded quickly, insisting that they did not discriminate against gay people in their hiring policies. Only Honeywell objected to hiring gay people. Later in the 1970s, when faced with a denial of access to students, Honeywell "quietly [reversed] its hiring policy".
The beginning of the 1970s saw Honeywell focus on process controls, with Honeywell merging their computer operations with GE's information systems in 1970, and later acquiring GE's process control business.$^{:122}$ With the acquisition, Honeywell took over responsibility for GE's ongoing Multics operating system project. The design and features of Multics greatly influenced the Unix operating system. Multics influenced many of the features of Honeywell/GE's GECOS and GCOS8 General Comprehensive Operating System operating systems. Honeywell, Groupe Bull, and Control Data Corporation formed a joint venture in Magnetic Peripherals Inc. which became a major player in the hard disk drive market.$^{:124}$
Honeywell was the worldwide leader in 14-inch disk drive technology in the OEM marketplace in the 1970s and early 1980s, especially with its SMD (Storage Module Drive) and CMD (Cartridge Module Drive). In the second half of the 1970s, Honeywell started to look to international markets again, acquiring the French Compagnie Internationale pour l’Informatique in 1976.$^{:124}$ In 1984, Honeywell formed Honeywell High Tech Trading to lease their foreign marketing and distribution to other companies abroad, in order to establish a better position in those markets.$^{:147}$ Under Binger's stewardship from 1961 to 1978 he expanded the company into such fields as defense, aerospace, and computing.
During and after the Vietnam Era, Honeywell's defense division produced a number of products, including cluster bombs, missile guidance systems, napalm, and land mines. Minnesota-Honeywell Corporation completed flight tests on an inertia guidance sub-system for the X-20 project at Eglin Air Force Base, Florida, utilizing an NF-101B Voodoo by August 1963. The X-20 project was canceled in December 1963. The Honeywell project, founded in 1968, organized protests against the company to persuade it to abandon weapons production
In 1980, Honeywell bought Incoterm Corporation to compete in both the airline reservations system networks and bank teller markets.

#### Honeywell Information Systems

In April 1955, Minneapolis-Honeywell started a joint venture with Raytheon called Datamatic to enter the computer market and compete with IBM.$^{:118}$ In 1957, their first computer, the DATAmatic 1000, was sold and installed. In 1960, just five years after embarking on this venture with Raytheon, Minneapolis-Honeywell bought Raytheon's interest in Datamatic and turned it into the Electronic Data Processing division, later Honeywell Information Systems (HIS) of Minneapolis-Honeywell.$^{:118}$
Honeywell purchased minicomputer pioneer Computer Control Corporation (3C's) in 1966, renaming it as Honeywell's Computer Control Division. Through most of the 1960s, Honeywell was one of the "Snow White and the Seven Dwarfs" of computing. IBM was "Snow White", while the dwarfs were the seven significantly smaller computer companies: Burroughs, Control Data Corporation, General Electric, Honeywell, NCR, RCA, and UNIVAC. Later, when their number had been reduced to five, they were known as "The BUNCH", after their initials: Burroughs, UNIVAC, NCR, Control Data Corporation, and Honeywell.
In 1970, Honeywell acquired GE's computer business, rebadging General Electric's 600-series mainframes to Honeywell 6000 series computers, supporting GCOS, Multics, and CP-6, while forming Honeywell Information Systems. In 1973, they shipped a high speed non-impact printer called the Honeywell Page Printing System. In 1975, it purchased Xerox Data Systems, whose Sigma computers had a small but loyal customer base. Some of Honeywell's systems were minicomputers, such as their Series 60 Model 6 and Model 62 and their Honeywell 200. The latter was an attempt to penetrate the IBM 1401 market.
In 1987, HIS merged with Groupe Bull, a global joint venture with Compagnie des Machines Bull of France and NEC Corporation of Japan to become Honeywell Bull. In 1988 Honeywell Bull was consolidated into Groupe Bull and in 1989 renamed to Bull, a Worldwide Information Systems Company. By 1991, Honeywell was no longer involved in the computer business.

### 1985–1999 integrations
#### Aerospace and defense

1986 marked a new direction for Honeywell, beginning with the acquisition of the Sperry Aerospace Group from the Unisys Corporation. In 1990, Honeywell spun off their Defense and Marine Systems business into Alliant Techsystems, as well as their Test Instruments division and Signal Analysis Center to streamline the company's focus. Honeywell continues to supply aerospace products including electronic guidance systems, cockpit instrumentation, lighting, and primary propulsion and secondary power turbine engines. In 1996, Honeywell acquired Duracraft and began marketing its products in the home comfort sector.
Honeywell is in the consortium that runs the Pantex Plant that assembles all of the nuclear bombs in the United States arsenal. Honeywell Federal Manufacturing & Technologies, successor to the defense products of AlliedSignal, operates the Kansas City Plant which produces and assembles 85 percent of the non-nuclear components of the bombs.

#### Home and building controls

Honeywell began the SmartHouse project, to combine heating, cooling, security, lighting, and appliances into one easily controlled system. They continued the trend in 1987 by releasing new security systems, and fire and radon detectors. In 1992, in another streamlining effort, Honeywell combined their Residential Controls, Commercial Systems, and Protections Services divisions into Home and Building Control, which then acquired the Enviracare air cleaner business.$^{:183}$ By 1995, Honeywell had condensed into three divisions: Space and Aviation Control, Home and Building Control, and Industrial Control.

#### Industrial control

Honeywell dissolved its partnership with Yamatake Company and consolidated its Process Control Products Division, Process Management System Division, and Micro Switch Division into one Industrial Control Group in 1998. It has further acquired Measurex System and Leeds & Northrup to strengthen its portfolio in 1997.

### 1999–2002 merger, takeovers
#### AlliedSignal and Pittway

On June 7, 1999, Honeywell was acquired by AlliedSignal, who elected to retain the Honeywell name for its brand recognition. The former Honeywell moved their headquarters of 114 years to AlliedSignal's in Morristown, New Jersey. While "technically, the deal looks more like an acquisition than a merger...from a strategic standpoint, it is a merger of equals." AlliedSignal's 1998 revenue was reported at $15.1 billion to Honeywell's $8.4 billion, but together the companies share huge business interests in aerospace, chemical products, automotive parts, and building controls.
The corporate headquarters were consolidated to AlliedSignal's headquarters in Morristown, New Jersey, rather than Honeywell's former headquarters in Minneapolis, Minnesota. When Honeywell closed its corporate headquarters in Minneapolis, over one thousand employees lost their jobs. A few moved to Morristown or other company locations, but the majority were forced to find new jobs or retire. Soon after the merger, the company's stock fell significantly, and did not return to its pre-merger level until 2007.
In 2000, the new Honeywell acquired Pittway for $2.2 billion to gain a greater share of the fire-protection and security systems market, and merged it into their Home and Building Control division, taking on Pittway's $167 million in debt. Analyst David Jarrett commented that "while Honeywell offered a hefty premium, it's still getting Pittway for a bargain" at $45.50 per share, despite closing at $29 the week before. Pittway's Ademco products complemented Honeywell's existing unified controls systems.

#### General Electric Company

In October 2000, Honeywell, then valued at over $21 billion, accepted a takeover bid from then-CEO Jack Welch of General Electric. The American Department of Justice cleared the merger, while "GE teams swooped down on Honeywell" and "GE executives took over budget planning and employee reviews." However, on July 3, 2001, the European Commission's competition commissioner, Mario Monti, blocked the move. This decision was taken on the grounds that with GE's dominance of the large jet engine market, led by the General Electric CF34 turbofan engine, its leasing services (GECAS), and Honeywell's portfolio of regional jet engines and avionics, the new company would be able to "bundle" products and stifle competition through the creation of a horizontal monopoly.
US regulators disagreed, finding that the merger would improve competition and reduce prices; United States Assistant Attorney General Charles James called the EU's decision "antithetical to the goals of antitrust law enforcement." This led to a drop in morale and general tumult throughout Honeywell. The then-CEO Michael Bonsignore was fired as Honeywell looked to turn their business around.

### 2002–2014 acquisitions and further expansion

In January 2002, Knorr-Bremse —who had been operating in a joint venture with Honeywell International Inc. —assumed full ownership of its ventures in Europe, Brazil, and the USA. Bendix Commercial Vehicle Systems became a subsidiary of Knorr-Bremse AG.
In February 2002, Honeywell's board appointed their next CEO and chairman, David M. Cote. Since 2002, Honeywell has made more than 80 acquisitions and 60 divestitures, and increasing its labor force to 131,000 as a result of these acquisitions. Honeywell's stock nearly tripled from $35.23 in April 2002 to $99.39 in January 2015.
Honeywell made a £1.2bn ($2.3bn) bid for Novar plc in December 2004. The acquisition was finalized in March 2005. In October 2005, Honeywell bought out Dow's 50% stake in UOP for $825 million, giving them complete control over the joint venture in petrochemical and refining technology. In May 2010, Honeywell outbid UK-based Cinven and acquired the French company Sperian Protection for $1.4 billion, which was then incorporated into its automation and controls safety unit.

### 2015–present

In 2015, the headquarters were moved to Morris Plains, New Jersey. The headquarters in Morris Plains included a 475,000-square-foot building on 40 acres.
In December 2015, Honeywell acquired Elster for US$5.1B, entering the space of gas, electricity, and water meters with a specific focus on smart meters. Honeywell International Inc. then acquired the 30% stake in UOP Russell LLC it didn't own already for roughly $240 million in January 2016.
In April 2016, Honeywell acquired Xtralis, a provider of aspirating smoke detection, perimeter security technologies, and video analytics software, for $480 million, from funds advised by Pacific Equity Partners and Blum Capital Partners. In May 2016, Honeywell International Inc. settled its patent dispute regarding Google subsidiary Nest Labs, whose thermostats Honeywell claimed infringed on several of its patents. Google parent Alphabet Inc. and Honeywell said they reached a "patent cross-license" agreement that "fully resolves" the long-standing dispute. Honeywell sued Nest Labs in 2012. In 2017, Honeywell opened a new software center in Atlanta, Georgia.
David Cote stepped down as CEO on April 1, 2017, and was succeeded by Darius Adamczyk, who had been promoted to president and chief operating officer (COO) in 2016. Cote served as executive chairman until April 2018. In October 2017, Honeywell announced plans to spin off its Homes, ADI Global Distribution, and Transportation Systems businesses into two separate, publicly traded companies by the end of 2018.
In 2018, Honeywell spun off both Honeywell Turbo Technologies, now Garrett Advancing Motion, and its consumer products business, Resideo. Both companies are publicly traded on the New York Stock Exchange. For the fiscal year 2019, Honeywell reported net income of US$6.230 billion, with an annual revenue of US$36.709 billion, a decrease of 19.11% over the previous fiscal cycle. Honeywell's market capitalization was valued at over US$113.25 billion in September 2020.
Honeywell relocated its corporate headquarters in October 2019 to Charlotte, North Carolina. In July 2019, Honeywell moved employees into a temporary headquarters building in Charlotte before their new building was complete.
In 2020, Honeywell Forge launched as an analytics platform software for industrial and commercial applications such as aircraft, building, industrial, worker and cyber-security. In collaboration with Carnegie Mellon University National Robotics Engineering Center, the Honeywell Robotics was created in Pittsburgh to focus on supply chain transformation. The Honeywell robotic unloader grabs packages in tractor-trailers then places them on conveyor belts for handlers to sort.
In May 2019, GoDirect Trade launched as an online marketplace for surplus aircraft parts such as engines, electronics, and APU parts. In March 2020, Honeywell announced that its quantum computer is based on trapped ions. Its expected quantum volume is at least 64, which Honeywell's CEO called the world's most powerful quantum computer. In November 2021, Honeywell announced the spinoff of its quantum division into a separate company named "Quantinuum".
In March 2023, Honeywell announced Vimal Kapur as its next CEO, effective June 1, 2023. In December 2023, Honeywell acquired Carrier Global's security business for nearly $5 billion to boost its automation portfolio.
In February 2024, Honeywell filed a lawsuit against Lone Star Aerospace, Inc., alleging that their software products infringe on five patents.
On October 1, 2024, Honeywell partnered with Google to integrate data with generative AI with an aim to streamline autonomous operations for its customers.
On October 8, 2024 it was announced that the company's advanced materials division would be spun-off into a new company.
On February 6, 2025 it was announced that Honeywell would be spun-off into three independent companies after activist investor Elliott Investment Management who is in favor of the split took a major stake in the company. With it's Aerospace, automation, and previously announced advanced materials segments being split into separate companies.

#### COVID-19 pandemic

In response to the COVID-19 pandemic, Honeywell converted some of its manufacturing facilities in Rhode Island, Arizona, Michigan and Germany to produce supplies of personal protective equipment for healthcare workers. In April 2020, Honeywell began production of N95 masks at the company's factories in Smithfield and Phoenix, aiming to produce 20 million masks a month. Honeywell's facilities in Muskegon and Germany were converted to produce hand sanitiser for government agencies.
Several state governments contracted Honeywell to produce N95 particulate-filtering face masks during the pandemic. The North Carolina Task Force for Emergency Repurposing of Manufacturing (TFERM) awarded Honeywell a contract for the monthly delivery of 100,000 N95 masks. In April 2020, Los Angeles Mayor Eric Garcetti announced a deal with Honeywell to produce 24 million N95 masks to distribute to healthcare workers and first responders.
In May 2020, United States President Donald Trump visited the Honeywell Aerospace Technologies facility in Phoenix, where he acknowledged the "incredibly patriotic and hard-working men and women of Honeywell" for making N95 masks and referred to the company's production as a "miraculous achievement".
In April 2021, Will.i.am and Honeywell collaborated on Xupermask, a mask made of silicon and athletic mesh fabric that has LED lights, 3-speed fans and noise-canceling headphones in the mask.
In November 2024, Honeywell announced its intention to sell its personal protective equipment business to Protective Industrial Products for almost $1.33 billion in cash. The sale of this PPE business is expected to close by the first half of 2025.
After the divestment of PPE business, the company is planning to retain its gas detection portfolio.

## Environmental issues

The United States Environmental Protection Agency states that no corporation has been linked to a greater number of Superfund toxic waste sites than Honeywell. In 2007, Honeywell ranked 44th in a list of US corporations most responsible for air pollution, releasing more than 4.25 million kg (9.4 million pounds) of toxins per year into the air. In 2001, Honeywell agreed to pay $150,000 in civil penalties and to perform $772,000 worth of reparations for environmental violations involving:
* failure to prevent or repair leaks of hazardous organic pollutants into the air
* failure to repair or report refrigeration equipment containing chlorofluorocarbons
* inadequate reporting of benzene, ammonia, nitrogen oxide, dichlorodifluoromethane, sulfuric acid, sulfur dioxide, and caprolactam emissions
In 2003, a federal judge in Newark, New Jersey, ordered the company to perform an estimated $400 million environmental remediation of chromium waste, citing "a substantial risk of imminent damage to public health and safety and imminent and severe damage to the environment." In 2003, Honeywell paid $3.6 million to avoid a federal trial regarding its responsibility for trichloroethylene contamination in Lisle, Illinois. In 2004, the State of New York announced that it would require Honeywell to complete an estimated $448 million cleanup of more than 74,000 kg (165,000 lbs) of mercury and other toxic waste dumped into Onondaga Lake in Syracuse, New York, from a former Allied Chemical property.
Honeywell established three water treatment plants by November 2014. The chemicals cleanup site removed 7 tons of mercury. In November 2015, Audubon New York gave the Thomas W. Keesee Jr. Conservation Award to Honeywell for its cleanup efforts in “one of the most ambitious environmental reclamation projects in the United States.” By December 2017, Honeywell completed dredging the lake. Later in December, the Department of Justice filed a settlement requiring Honeywell to pay a separate $9.5 million in damages, as well build 20 restoration projects on the shore to help repair the greater area surrounding the lake.
In 2005, the state of New Jersey sued Honeywell, Occidental Petroleum, and PPG to compel cleanup of more than 100 sites contaminated with chromium, a metal linked to lung cancer, ulcers, and dermatitis. In 2008, the state of Arizona made a settlement with Honeywell to pay a $5 million fine and contribute $1 million to a local air-quality cleanup project, after allegations of breaking water-quality and hazardous-waste laws on hundreds of occasions between 1974 and 2004.
In 2006, Honeywell announced that its decision to stop manufacturing mercury switches had resulted in reductions of more than 11,300 kg (24,900 lb) of mercury, 2,800 kg (6,200 lb) of lead, and 1,500 kg (3,300 lb) of chromic acid usage. The largest reduction represents 5% of mercury use in the United States. The EPA acknowledged Honeywell's leadership in reducing mercury use through a 2006 National Partnership for Environmental Priorities (NPEP) Achievement Award for discontinuing the manufacturing of mercury switches.

## Criticism

On March 10, 2013, The Wall Street Journal reported that Honeywell was one of sixty companies that shielded annual profits from U.S. taxes. In December 2011, the non-partisan organization Public Campaign criticized Honeywell International for spending $18.3 million on lobbying and not paying any taxes during 2008–2010, instead getting $34 million in tax rebates, despite making a profit of $4.9 billion, laying off 968 workers since 2008, and increasing executive pay by 15% to $54.2 million in 2010 for its top five executives.
Honeywell has also been criticized in the past for its manufacture of deadly and maiming weapons, such as cluster bombs.

### Allegations of involvement in Gaza

In June 2024, investigative reports from various sources alleged that Honeywell's manufactured components were used in a missile that targeted a school in Gaza. Al Jazeera’s investigation traced the part’s serial numbers back to Honeywell, raising concerns about U.S. involvement in these military operations. This attack resulted in numerous civilian casualties, sparking international condemnation. Honeywell has not provided a detailed response regarding these claims.
