William W. Schwarzer (born 1925) is a United States federal judge serving on the U.S. District Court for the Northern District of California.
Born in Berlin, Germany, Schwarzer served in the United States Army during World War II, beginning in 1943. He attained the rank of Second Lietuenant, and was discharged in 1947. He received an A.B. (cum laude) at the University of Southern California in 1948, and an L.L.B. with honors from Harvard Law School in 1951, where he was a member of the Harvard Legal Aid Bureau, and where he also served as a teaching fellow from 1951 to 1952.
He entered private practice in San Francisco, California in 1952 as an associate at McCutchen, Doyle, Brown & Enersen (now Bingham McCutchen). He became a partner at the firm in 1960 and continued with McCutchen until his appointment to the federal bench in 1976. He served as senior counsel to the President's Commission on CIA Activities within the United States (better known as the Rockefeller Commission) in 1975.
On June 2, 1976, Schwarzer was nominated by President Gerald Ford to a seat on the United States District Court for the Northern District of California vacated by Albert C. Wollenberg. Schwarzer was confirmed by the United States Senate on July 23, 1976, and received his commission the same day. In 1986, Schwarzer worked with Rod McManigal to tighten up Schwarzer's libretto to Galileo, a Grove Play performed at the Bohemian Grove. Schwarzer joined the Bohemian Club in 1979.
He also presided over a lawsuit filed by Apple Computer against Microsoft, in which Apple alleged that Microsoft used some Apple features in Windows Version 2.03, and later 3.0. On January 5, 1989, Schwarzer dropped all but 10 of the 189 claims that Apple brought against Microsoft. He assumed senior status on April 30, 1991, and also served as the director of the Federal Judicial Center from 1990 to 1995.
