William Henry Crocker (13 January 1861 – 25 September 1937), was president of Crocker National Bank.
He attended Phillips Academy, Andover and Yale University, where he was a brother of the Delta Kappa Epsilon fraternity (Phi chapter). After the 1906 earthquake and fire had left the Crocker mansions in ruins, in 1907 he donated the Crocker family's 2.6-acre (11,000 m2) Nob Hill block for Grace Cathedral.
He was a member of the University of California Board of Regents for nearly thirty years and funded the Lawrence Radiation Laboratory's million-volt x-ray tube at the UC hospital and the "medical" Crocker cyclotron used for neutron therapy at the Berkeley. 
Crocker also chaired the Panama-Pacific Exposition Committee and SE Community Chest, and was a key member of the committee that built the San Francisco Opera House and Veterans Building. Crocker was the founder of Crocker Middle School located in Hillsborough, California.
When much of the city of San Francisco was destroyed by the fire from the 1906 earthquake, William Crocker and his bank were major forces in financing reconstruction. His father, Charles Crocker (1822-1888), had been a builder of the Central Pacific Railroad.
In the 1890s, his wifey, in part, lent William Kingston Vickery, owner of the San Francisco art gallery Vickery, Atkins & Torrey, a number of French Impressionist paintings. Vickery then supervised a series of these loan exhibitions in San Francisco and introduced Impressionism to California in the form of paintings by Monet, Eugene Boudin, Paul Cézanne, Camille Pissarro, Pierre-Auguste Renoir, and Edgar Degas. These pictures were lent by California Impressionist Lucy Bacon (who studied in France under Pissarro and met Cézanne), as well as Mrs. William H. Crocker, who was the leading California patron of French Impressionist art at the time.
Mrs. Crocker also sponsored studies of the Zoellner Quartet with César Thomson in Belgium. After six years in Europe, the quartet would return to the United States and become a tireless force promoting classical music outside established centers and in southern California.
His cousin, Aimee Crocker, was a Bohemian mystic who garnished publicity for her extravagant parties in New York, San Francisco and Paris, for her 5 husbands and many lovers, for her tattoos, and for living 10 years in the Far East, not as a tourist, but as a native.
The public middle school in Hillsborough, California is named after him, Crocker Middle School.
