B.S., Electrical Engineering, 1975
Co-founder, Sun Microsystems
With Scott McNealy, Bill Joy is a co-founder of Sun Microsystems. Sun was an important driver of the development of the Internet, producing workstations and servers that made it easier for businesses to grow on the Web.
While at Sun, Joy helped create the Java programming language, which for the first time allowed developers to create applications viewable on any computer. Joy was also a creator of the BSD UNIX, one of the first operating systems with built in Internet connectivity. Parts of the BSD UNIX code are still used in current computing systems.
Joy has been involved with two venture capital firms, HighBAR Ventures, founded with two colleagues from Sun; and Kleiner Caulfield & Byers, where he became a partner in 2005.
