Andy Hertzfeld (born April 6, 1953) is an American computer scientist and inventor who was a member of the original Apple Macintosh development team during the 1980s. After buying an Apple II in January 1978, he went to work for Apple Computer from August 1979 until March 1984, where he was a designer for the Macintosh system software. Since leaving Apple, he has co-founded three companies: Radius in 1986, General Magic in 1990 and Eazel in 1999. In 2002, he helped Mitch Kapor promote open source software with the Open Source Applications Foundation. Hertzfeld joined Google in 2005, and in 2011 was the key designer of the Circles user interface in Google+. Hertzfeld was portrayed by Elden Henson in the 2013 film ''Jobs'', and by Michael Stuhlbarg in the 2015 film ''Steve Jobs''. ==Apple Computer (1979–1984)== After graduating from Brown University with a Computer Science degree in 1975, Hertzfeld attended graduate school at the University of California, Berkeley. In 1978, he bought an Apple II computer and soon began developing software for it. He was hired by Apple Computer as a systems programmer in 1979 and developed the Apple SilenType printer firmware and wrote the firmware〔M&R Enterprises, Sup'R'Terminal Manual, page 47, 1980.〕 for the Sup'R'Terminal, the first 80-column card for the Apple II. In the early 1980s, he invited his high school friend, artist Susan Kare, to join Apple in order to help design what would become standard Macintosh icons. Hertzfeld was a member of the Apple Macintosh design team. After a shakeup in the Apple II team and at Hertzfeld's request, Apple co-founder Steve Jobs added him to the nearly two-year-old team in February 1981. Working for Bud Tribble alongside Bill Atkinson and Burrell Smith, Hertzfeld became a primary software architect of the Macintosh Operating System, which was considered revolutionary in its use of the graphical user interface (GUI) where Jef Raskin also made contributions. Hertzfeld's business card at Apple listed his title as ''Software Wizard''. He wrote large portions of the Macintosh's original system software, including much of the ROM code, the User Interface Toolbox, and a number of innovative components now standard in many graphic user interfaces, like the Control Panel and Scrapbook. 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「Andy Hertzfeld」の詳細全文を読む スポンサード リンク
