Bill was a native San Franciscan born on March 19th, 1931 to George and Irene Diamond (Koutsonicoli) of Peloponnesus, Greece. Several years after graduating from George Washington High School in 1948, he served in the United States Navy during the Korean War, he returned home after serving his country and earned a teaching degree at San Francisco State University.

After graduation, Bill became a substitute teacher for the San Francisco Unified School District where he taught at various schools throughout the city. Abraham Lincoln High School is where he spent most of his career teaching algebra, geometry, history, and computer science. Many of his former high school students still refer to him as, “Mr. Diamond” or “Mr. D”, he is best remembered for his lively classroom, unique teaching style, and especially how he helped them understand the language of mathematics.

After retirement from the SFUSD, he enjoyed taking his Yorkshire Terriers for their daily walks, ballroom dancing, swimming, cooking, traveling, and reading the daily newspaper at the local donut shop.

Bill was predeceased by his parents, and half-sister, Eleni. He is survived by his loving children William (Billy) Diamond, Jr., Michael Diamond, Phillip Diamond, Athena Diamond Rivera, and Maria Diamond Olla and his adoring grandchildren, Monalisa, Alex, Daniel, Christian, Arianna, Katrina, and Eleni. May he rest in peace… ∞
