John Edward Warnock (born October 6, 1940) is an American computer scientist and businessman best known as the co-founder with Charles Geschke of Adobe Systems Inc., the graphics and publishing software company. Dr. Warnock was President of Adobe for his first two years and Chairman and CEO for his remaining sixteen years at the company. Although retired as CEO in 2000, he still co-chairs the board with Geschke. Warnock has pioneered the development of graphics, publishing, Web and electronic document technologies that have revolutionized the field of publishing and visual communications. ==Life and career== Warnock was born and raised in Salt Lake City, Utah. He graduated from Olympus High School (1958), but failed mathematics in ninth grade.〔 He currently lives in the San Francisco Bay Area. He is married and has three children. Warnock has a Bachelor of Science in Mathematics and Philosophy, a Master of Science in Mathematics, a Ph.D. in Electrical Engineering (Computer Science), and an honorary degree in Science, all from the University of Utah. At the University of Utah he was a member of the Gamma Beta Chapter of the Beta Theta Pi Fraternity.〔(AirSet ). Utah-beta.org. Retrieved on 2013-07-21.〕 He also has an honorary degree from the American Film Institute. In 1976, while Warnock worked at Evans & Sutherland, a Salt Lake City-based computer graphics company, the concepts of the PostScript language were seeded. Prior to co-founding Adobe, with Geschke and Putman, Warnock worked with Geschke at Xerox's Palo Alto Research Center (Xerox PARC), where he had started in 1978. Unable to convince Xerox management of the approach to commercialize the InterPress graphics language for controlling printing, he, together with Geschke and Putman, left Xerox to start Adobe in 1982. At their new company, they developed an equivalent technology, PostScript, from scratch, and brought it to market for Apple's LaserWriter in 1984. Warnock's earliest publication and subject of his master's thesis, was his 1964 proof of a theorem solving the Jacobson radical for row-finite matrices, which was originally posed by the American mathematician Nathan Jacobson in 1956. In his 1969 doctoral thesis, Warnock invented the Warnock algorithm for hidden surface determination in computer graphics.〔, 32 pages〕 It works by recursive subdivision of a scene until areas are obtained that are trivial to compute. It solves the problem of rendering a complicated image by avoiding the problem. If the scene is simple enough to compute then it is rendered; otherwise it is divided into smaller parts and the process is repeated.〔, 608 pages〕 Warnock notes that for this work he received "the dubious distinction of having written the shortest doctoral thesis in University of Utah history".〔 〕 In the Spring of 1991, Warnock outlined a system called "Camelot", that evolved into the Portable Document Format (PDF) file-format. The goal of Camelot was to "effectively capture documents from any application, send electronic versions of these documents anywhere, and view and print these documents on any machines". Warnock's document contemplated, "Imagine if the IPS (Interchange PostScript) viewer is also equipped with text searching capabilities. In this case the user could find all documents that contain a certain word or phrase, and then view that word or phrase in context within the document. Entire libraries could be archived in electronic form..." One of Adobe's popular typefaces, Warnock, is named after him. Adobe's PostScript technology made it easier to print text and images from a computer, revolutionizing media and publishing in the 1980s. In 2003 Warnock and his wife donated 200,000 shares of Adobe Systems valued at over 5.7 million dollars〔 〕 to the University of Utah as the main gift for a new engineering building. The John E. and Marva M. Warnock Engineering Building was completed in 2007 and houses the Scientific Computing and Imaging Institute and the Dean of the University of Utah College of Engineering. Dr. Warnock holds seven patents. In addition to Adobe Systems, he serves or has served on the board of directors at ebrary, Knight-Ridder, MongoNet, Netscape Communications and Salon Media Group. Warnock is a past Chairman of the Tech Museum of Innovation in San Jose. He also serves on the Board of Trustees of the American Film Institute and the Sundance Institute. Hobbies include photography, skiing, Web development, painting, hiking, curation of rare scientific books and historical Native American objects. A strong supporter of higher education, Warnock and his wife, Marva, have supported three presidential endowed chairs in computer science, mathematics and fine arts at the University of Utah and also an endowed chair in medical research at Stanford University. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Warnock」の詳細全文を読む スポンサード リンク
