Jean-Louis Gassée (born March 1944 in Paris, France) is a business executive. He is best known as a former executive at Apple Computer, where he worked from 1981 to 1990. He also founded Be Inc., creators of the BeOS computer operating system. After leaving Be, he became Chairman of PalmSource, Inc. in November 2004.
 Gassée worked for six years at Hewlett-Packard from 1968 to 1974, where he was responsible for overseeing the launching of the company’s first desktop scientific computer and the development of its sales organization in France, before his promotion to Sales Manager of Europe, in Geneva, Switzerland.  From 1974 to 1981, Gassée served as the Chief Executive Officer of the French affiliates of Data General and Exxon Office Systems.
 In 1981, Gassée became Director of European Operations at Apple Computer.  In 1985, after learning of Steve Jobs's plan to oust CEO John Sculley over Memorial Day weekend while Sculley was in China, Gassée preemptively informed the board of directors, which eventually led to Jobs leaving Apple.
 Later, Sculley personally appointed Gassée to Jobs's old position as head of Macintosh development. Gassée introduced several Macintosh products on-stage in the late 1980s including the Macintosh Portable in 1989, and also the Macintosh IIfx. In his product introductions, he was often very comical. Gassée was less formal than many executives. He wore tailored suits when necessary, but he often addressed employees wearing a black (lambskin) leather jacket and a single diamond-stud earring[citation needed].
 When the idea of licensing the Mac OS for other companies use was brought up by various members of Apple, Jean-Louis refused to give in to the idea, maintaining that the Macintosh was more powerful than any other computer at the present, and had a superior architectural roadmap for future expansion than any other computer. Although many of the companies were interested (such as AT&T, for the use of the OS in their own equipment—they were so interested in this idea that the then-CEO of AT&T made a personal phone call to Sculley), Gassée would have none of it, and so the idea of licensing the Mac OS was shelved.
 In the mid-1980s, Gassée started the skunkworks project to create what eventually became the Newton MessagePad.
 In 1987, Apple CEO John Sculley published his memoir Odyssey. In the hope of inspiring "excellence," he ordered a hardback copy for each Apple employee, at Apple's expense[citation needed]. Shortly afterward, Gassée ordered a paperback copy of Fred Brooks's The Mythical Man-Month for all product-development employees, in the hope of inspiring good sense in project management. Brooks gave a lecture at nearby De Anza College: the room was filled with Apple employees with copies of his book, who told him stories that confirmed his conclusions[citation needed].
 In 1988, Gassée became head of Apple's advanced product development and worldwide marketing, and rumors of his taking over as president of Apple from Sculley were circling. Other rumors concerning Michael Spindler were also circulating. At one point in 1990, a number of Apple employees held a demonstration, marching around in circles, carrying signs, on the lawn in front of one Apple building, to petition Apple management to retain Gassée. A USA Today reporter saw the demonstration and asked an employee what it was about. The employee, well aware of Apple's rules on divulging trade secrets to the press, succinctly explained the issues. The next day, USA Today reported that Apple employees, many wearing black leather jackets and berets in honor of Gassée, had demonstrated to persuade management to keep him at Apple. In fact, the only person wearing a leather jacket (a brown goatskin A-2) and a beret had been the person whom she had asked to explain the purpose of the demonstration.
 In 1989, Gassée successfully killed a Claris project, 'Drama', which aimed to start a new brand to sell low-end Macintosh computers. Gassée argued that consumers would continue to be willing to pay the price premium for a full Macintosh experience.
 Despite Gassée's efforts and those of his supporters, in 1990 he left Apple, forced out by Sculley and Apple board members dissatisfied with his performance in delivering new products[citation needed]. Spindler got the top job.
 In 1991, Gassée started a new venture, Be Inc., with the ambitious goal of creating an entire new computer platform, hardware and software, from the ground up. A number of Apple employees left with him, including Steve Sakoman, the developer of the Apple Newton. Be developed a new operating system, optimized for multiple CPUs and multithreaded applications, which became known simply as "the Be Operating System," or BeOS.
 BeOS was written for Be's own dual-processor machine, the BeBox; later development releases of BeOS were ported to run on the Macintosh, and Macintosh clone makers, including Power Computing and Motorola, signed deals to ship BeOS with their hardware when the OS was finalized. In light of this, Be stopped production on the BeBox after selling only around 2000 units, and focused entirely on development of BeOS.
 In 1996, Apple Computer decided to abandon Copland, the project to rewrite and modernize the Macintosh operating system. BeOS had many of the features Apple sought, and around Christmas time they offered to buy Be for $120 million, later raising their bid to $200 million. However, despite estimates of Be's total worth at approximately $80 million,[citation needed] Gassée held out for $275 million, and Apple balked. In a surprise move, Apple went on to purchase NeXT, the company their former co-founder Steve Jobs had earlier left Apple to found, for $429 million, with the high price justified by Apple getting Jobs and his NeXT engineers in tow. NeXTSTEP was used as the basis for their new operating system, Mac OS X.
 After the return of Jobs, Apple withdrew the license to make Macintosh clones. With Intel's assistance, BeOS moved to "Plan B", a port to the x86 platform. While it arguably never grew past a cult following, it sold enough copies to have a nascent development and user community, and had several thousand programs available for it, including several dozen commercial products. BeOS was also used as an embedded operating system in multimedia production systems from Edirol, TEAC and Level Control Systems. However, partially due to behind-the-scenes pressure from Microsoft, Be was not successful in getting top-tier OEMs to bundle BeOS with their hardware - only Hitachi and AST (who were major in Europe at the time) did so - which Gassée saw as fundamental to their success.
 At the end of 1999, Be had a "focus shift," giving their desktop OS away for free (with commercial distributions sold by third-party vendors, similar to Linux distributions) to focus on BeIA, a build of BeOS specifically targeted to internet appliances. The company lost several employees who disagreed with this strategy and who had no desire to work on an appliance OS.[citation needed] While there was vendor interest in BeIA and at least one shipping product based on it (the Sony eVilla), the market for internet appliances proved to be nearly non-existent, and Be laid off most of its employees in 2001, with its assets and the remaining engineers being bought by Palm, Inc. for $11 million that August. Gassée stayed on through that transition, but left in January 2002.
 After leaving Be, Gassée served as president and CEO of Computer Access Technology Corporation (CATC), a company which made network protocol analyzers, but left within a year (CATC was purchased in fall 2004 by LeCroy Corporation, a competitor). Gassée resurfaced as a general partner at Allegis Capital, a venture capital fund based in Palo Alto, California, where he is still in position.
 In November 2004, Gassée became chairman of PalmSource, Inc., where several former Be executives and engineers still worked. BeOS technology was being worked on for use in Palm OS "Cobalt" (Version 6), but as of February 2006, there were no major customers—including Palm, Inc. itself—who have committed to using the Cobalt release.
 In March 2006, he started writing a French-language blog called Le blog de Jean-Louis Gassée (English: Jean-Louis Gassée's Blog). The blog was active for a month and contains only four entries.
 In 2009, he started contributing regularly to the Monday Note blog, a newsletter covering the intersection of media and technology.
