The Hon. William Alsup is a district judge on the United States District Court for the Northern District of California. He was nominated to the bench by former President Bill Clinton on March 24, 1999, filling a seat vacated by the Hon. Thelton Henderson.
Alsup earned a B.S. in mathematics from Mississippi State University in 1967. He then continued his studies, completing a J.D. from Harvard Law School and an M.P.P. from Harvard University in 1971.
He began his legal career as a law clerk for Justice William O. Douglas of the Supreme Court of the United States in 1971. The following year, he accepted a position as an attorney at Morrison & Foerster in San Francisco. Then, in 1978, he took a leave of absence from the firm in order to serve as assistant to the United States Solicitor General in the United States Department of Justice. He served there for two years, eventually returning to Morrison & Foerster in 1980. He practiced at Morrison & Foerster for the next eighteen years but briefly left to serve a short stint as special counsel in the Antitrust Division of the United States Department of Justice in 1998. Later that year, he returned once again to Morrison & Foerster. He practiced there until his nomination to the bench in 1999.
