known as Microsoft to create Microsoft Word. Simonyi later became the first repeat space tourist, blasting off on Russian Soyuz rockets to work at the International Space Station orbiting the earth. In 1977, a graduate student in the computer science department named Bill Joy (MS 1982) assembled the original Berkeley Software Distribution, commonly known as BSD Unix. Joy, who went on to co-found Sun Microsystems, also developed the original version of the terminal console editor vi, while Ken Arnold (BA 1985) created Curses, a terminal control library for Unix-like systems that enables the construction of text user interface (TUI) applications. Working alongside Joy at Berkeley were undergraduates William Jolitz (BS 1997) and his future wife Lynne Jolitz (BA 1989), who together created 386BSD, a version of BSD Unix that runs on Intel CPUs and evolved into the BSD family of free operating systems and the Darwin operating system underlying Apple Mac OS X. Eric Allman (BS 1977, MS 1980) created SendMail, a Unix mail transfer agent that delivers about 12 percent of the email in the world. The XCF, an undergraduate research group located in Soda Hall, has been responsible for a number of notable software projects, including GTK+ (created by Peter Mattis, BS 1997), The GIMP (Spencer Kimball, BS 1996), and the initial diagnosis of the Morris worm. In 1992, Pei-Yuan Wei, an undergraduate at the XCF, created ViolaWWW, one of the first graphical web browsers. ViolaWWW was the first browser to have embedded scriptable objects, stylesheets, and tables. In the spirit of Open Source, he donated the code to Sun Microsystems, inspiring Java applets( Kim Polese (BS 1984) was the original product manager for Java at Sun Microsystems.) ViolaWWW also inspired researchers at the National Center for Supercomputing Applications to create the Mosaic web browser, a pioneering web browser that became Microsoft Internet Explorer. Alumni collectively have won at least twenty-five Pulitzer Prizes. Pulitzer Prize–winning journalist Marguerite Higgins (BA 1941) was a pioneering female war correspondent who covered World War II, the Korean War, and the Vietnam War. Novelist Robert Penn Warren (MA 1927) won three Pulitzer Prizes, including one for his novel All the King's Men, which was later made into an Academy Award-winning movie. Pulitzer Prize–winning cartoonist Rube Goldberg (BS 1904) invented the comically complex—yet ultimately trivial—contraptions known as Rube Goldberg machines. Journalist Alexandra Berzon (MA 2006) won a Pulitzer Prize in 2009, and journalist Matt
