Jamie Zawinski (born November 3, 1968), commonly known as jwz, is an American computer programmer, blogger and impresario. He is best known for his role in the creation of Netscape Navigator, Netscape Mail, Lucid Emacs, Mozilla.org, and XScreenSaver. He is also the proprietor of DNA Lounge, a nightclub and live music venue in San Francisco. Biography Zawinski's programming career began at age 16 with Scott Fahlman's Spice Lisp project at Carnegie Mellon University. He then worked at AI startup Expert Technologies, Inc. followed by Robert Wilensky and Peter Norvig's AI research group at UC Berkeley, working on natural language processing. In 1990 he began working at Lucid Inc., first working on Lucid Common Lisp, and then on Lucid's Energize C++ IDE. Lucid decided to use GNU Emacs as the text editor for their IDE due to its free license, popularity, and extensibility, and Zawinski led that project. As Zawinski and the other programmers made fundamental changes to GNU Emacs to add new functionality, tensions over how to merge these patches into the main tree eventually led to the fork of the project into GNU Emacs and Lucid Emacs (now XEmacs). In 1992 he released the first version of XScreenSaver, a free and open-source collection now containing more than 240 screensavers. Initially released for Unix, it now supports macOS, iOS and Android as well. On Unix systems, it also provides the framework for blanking and locking the screen. He still maintains it, with new releases coming out several times a year. Netscape and Mozilla Following Lucid's bankruptcy in 1994, Zawinski was one of the initial employees of Mosaic Communications, later known as Netscape. At Netscape, he developed the Unix release of Netscape Navigator 1.0, and later, Netscape Mail, the first mail reader (or Usenet reader) to natively support HTML. Zawinski came up with the name "Mozilla" (originally the internal code-name of the web browser) during a staff meeting, as a reference to Godzilla and a portmanteau of "Mosaic killer". An easter egg he coded in the Netscape browser became quite well known during the early days of the World Wide Web: typing "about:jwz" into the address box would take the user to his home page, and would change the browser's logo animation to a fire-breathing dragon. Through his long-time support and advocacy for free software both inside and outside the company, Zawinski is credited with having been the inspiration for Netscape's
