George Christopher (December 8, 1907 – September 14, 2000) was a Greek-American politician, and the 34th Mayor of San Francisco, serving in that office from January 1956 until January 1964. He was, as of 2012, the last Republican to be elected mayor of San Francisco; all San Francisco mayors since he left office have been Democrats.
Born George Christophes in Arcadia, Greece, the son of James Christophes and Mary Koines Christophes, Christopher and his family emigrated to the United States in 1910 and settled in San Francisco's South of Market Street neighborhood, then known as "Greektown", when Christopher was two years old. Christopher left day school at the age of fourteen when his father James died, and he became sole support of his family. He sold papers, then talked his way into a job at the San Francisco Examiner as a copy boy. In 1935, he married Tula Sarantitis, daughter of a baker whom George did bookkeeping for.
After studying accounting at Golden Gate College from which he earned a BA in Accounting in 1930, he worked for numerous small firms keeping their accounts and eventually bought out a small dairy on Fillmore Street, which became the Christopher Dairy. He was prosecuted in the 1940s for breaking the newly passed milk price-fixing laws.
