Question: Who founded the company that made Vacamatic?

full_context: Document 1: Jeep: Jeep is a brand of American automobile and division of FCA US LLC (formerly Chrysler Group, LLC), a wholly owned subsidiary of the Italian-American corporation Fiat Chrysler Automobiles. Jeep has been a part of Chrysler since 1987, when Chrysler acquired the Jeep brand, along with remaining assets, from its previous owner American Motors Corporation (AMC).
Document 2: Clement O. Miniger: Clement O. Miniger (November 11, 1874 – April 23, 1944) was an American industrialist and philanthropist. He founded the 'Electric Auto-Lite Company' (now part of Honeywell) in 1911, acting as the company's president until 1934 and its chairman of the board from 1934 to 1944.
Document 3: Plymouth Prowler: The Plymouth Prowler, later the Chrysler Prowler, is a retro-styled production car manufactured and marketed from 1997 to 2002 by DaimlerChrysler, based on the 1993 concept car of the same name.
Document 4: Simca: Simca (; Mechanical and Automotive Body Manufacturing Company) was a French automaker, founded in November 1934 by Fiat and directed from July 1935 to May 1963 by Italian Henri Théodore Pigozzi. Simca was affiliated with Fiat and, after Simca bought Ford's French activities, became increasingly controlled by the Chrysler Group. In 1970, Simca became a subsidiary and brand of Chrysler Europe, ending its period as an independent company. Simca disappeared in 1978, when Chrysler divested its European operations to another French automaker, PSA Peugeot Citroën. PSA replaced the Simca brand with Talbot after a short period when some models were badged as Simca-Talbots.
Document 5: Four-wheel drive: American Motors introduced the innovative Eagle for the 1980 model year. These were the first American mass production cars to use the complete front - engine, four - wheel drive system. The AMC Eagle was offered as a sedan, coupe, and station wagon with permanent automatic all - wheel - drive passenger models. The new Eagles combined Jeep technology with an existing and proven AMC passenger automobile platform. They ushered a whole new product category of ``sport - utility ''or crossover SUV. AMC's Eagles came with the comfort and high - level appointments expected of regular passenger models and used the off - road technology for an extra margin of safety and traction.
Document 6: Kaiser Motors: Kaiser Motors (formerly Kaiser-Frazer) Corporation made automobiles at Willow Run, Michigan, United States, from 1945 to 1953. In 1953, Kaiser merged with Willys-Overland to form Willys Motors Incorporated, moving its production operations to the Willys plant at Toledo, Ohio. The company changed its name to Kaiser Jeep Corporation in 1963.
Document 7: Vacamatic: The 1941 M4 Vacamatic transmission by Chrysler was, historically, the first semi-automatic transmission which was marketed by a major manufacturer. It was an attempt to compete against rivals' automatic transmissions, though it still had a clutch, primarily to change range. In normal driving, the clutch is not used. The transmission itself was a fully synchronised manual type, with four forward gears, one reverse; where the shifting was done 'automatically' by either vacuum cylinders (early, M4), or hydraulic cylinders (late, M6, Presto-Matic). The main difference was the addition of a fluid coupling between engine and clutch, and the shifting mechanism.
Document 8: Vacuum: Manifold vacuum can be used to drive accessories on automobiles. The best-known application is the vacuum servo, used to provide power assistance for the brakes. Obsolete applications include vacuum-driven windscreen wipers and Autovac fuel pumps. Some aircraft instruments (Attitude Indicator (AI) and the Heading Indicator (HI)) are typically vacuum-powered, as protection against loss of all (electrically powered) instruments, since early aircraft often did not have electrical systems, and since there are two readily available sources of vacuum on a moving aircraft—the engine and an external venturi. Vacuum induction melting uses electromagnetic induction within a vacuum.
Document 9: Washing machine: Bendix Home Appliances, a subsidiary of Avco, an otherwise unrelated company, who licensed the name from Bendix Corporation, introduced the first domestic automatic washing machine in 1937, having applied for a patent in the same year. In appearance and mechanical detail, this first machine was not unlike the front loading automatic washers produced today. Although it included many of the today's basic features, the machine lacked any drum suspension and therefore had to be anchored to the floor to prevent ``walking ''. Because of the components required, the machine was also very expensive. For instance, the Bendix Home Laundry Service Manual (published November 1, 1946) shows that the drum speed change was facilitated by a 2 - speed gearbox built to a heavy duty standard (not unlike a car automatic gearbox, albeit at a smaller size). The timer was also probably fairly costly, because miniature electric motors were expensive to produce.
Document 10: History of the automobile: In the United States, brothers Charles and Frank Duryea founded the Duryea Motor Wagon Company in 1893, becoming the first American automobile manufacturing company. The Autocar Company, founded in 1897, established a number of innovations still in use and remains the oldest operating motor vehicle manufacturer in the United States However, it was Ransom E. Olds and his Olds Motor Vehicle Company (later known as Oldsmobile) who would dominate this era of automobile production. Its production line was running in 1901. The Thomas B. Jeffery Company developed the world's second mass - produced automobile, and 1,500 Ramblers were built and sold in its first year, representing one - sixth of all existing motorcars in the United States at the time. Within a year, Cadillac (formed from the Henry Ford Company), Winton, and Ford were also producing cars in the thousands.
Document 11: Walter Chrysler: Walter Percy Chrysler (April 2, 1875 – August 18, 1940) was an American automotive industry executive and founder of Chrysler Corporation, now a part of Fiat Chrysler Automobiles.
Document 12: History of the automobile: In 1870 Siegfried Marcus built the first gasoline powered combustion engine, which he placed on a pushcart, building four progressively sophisticated combustion - engine cars over a 10 - to - 15 - year span that influenced later cars. Marcus created the two - cycle combustion engine. The car's second incarnation in 1880 introduced a four - cycle, gasoline - powered engine, an ingenious carburetor design and magneto ignition. He created an additional two models further refining his design with steering, a clutch and brakes.
Document 13: Automatic transmission: The automatic transmission was invented in 1921 by Alfred Horner Munro of Regina, Saskatchewan, Canada, and patented under Canadian patent CA 235757 in 1923. (Munro obtained UK patent GB215669 215,669 for his invention in 1924 and US patent 1,613,525 on 4 January 1927). Being a steam engineer, Munro designed his device to use compressed air rather than hydraulic fluid, and so it lacked power and never found commercial application. The first automatic transmission using hydraulic fluid may have been developed in 1932 by two Brazilian engineers, José Braz Araripe and Fernando Lehly Lemos; subsequently the prototype and plans were sold to General Motors who introduced it in the 1940 Oldsmobile as the ``Hydra - Matic ''transmission. They were incorporated into GM - built tanks during World War II and, after the war, GM marketed them as being`` battle - tested.'' However, a Wall Street Journal article credits ZF Friedrichshafen with the invention, occurring shortly after World War I. ZF's origins were in manufacturing gears for airship engines beginning in 1915; the company was founded by Ferdinand von Zeppelin.
Document 14: Klaus von Oertzen: During 1932, four motor manufacturers of Saxony in Germany, namely Audi, DKW, Horch and Wanderer, amalgamated under the pressures of the depressed German economy to form Auto Union. The new company’s four-ringed emblem, which von Oertzen suggested, can still be seen in the modern Audi logo. Baron von Oertzen, who had been in charge of sales at Wanderer, became sales director and chairman of the board of directors of Auto Union.
Document 15: TorqueFlite: TorqueFlite (also seen as Torqueflite) is the trademarked name of Chrysler Corporation's automatic transmissions, starting with the three-speed unit introduced late in the 1956 model year as a successor to Chrysler's two-speed PowerFlite. In the 1990s, the TorqueFlite name was dropped in favor of alphanumeric designations, although the latest ZF-based transmissions with the 8-speed automatic has revived the name.
