“Francis Xavier Williams: Entomologist (1882-1967). Francis Xavier Williams was born on August 6, 1882, in Marquez, California. His family moved to San Francisco in 1887, and he quickly became immersed in natural history, particularly insects. He became acquainted with research at the California Academy of Sciences early in life through the entomologist and physician Edwin C. Van Dyke (1869-1952). Williams was an undergraduate at Stanford University during the 1905-1906 Galapagos expedition, graduating in 1908. He worked as a plant inspector at the Ferry Building in San Francisco from 1908 to 1910, then went to the University of Kansas as an assistant entomologist at the Hawaiian Sugar Planters' Experiment Station. He traveled widely in the United States, conducting research in entomology, and in Guatemala, Australia, Philippines, Ecuador, Trinidad, British Guiana, Barbados, Brazil, New Caledonia, and East Africa.

Williams is the only member of the 1905-1906 expedition for whom a tape recording of his voice exists in the archives of the California Academy of Sciences. Toward the end of his life, he was closely associated with the San Diego Museum of Natural History. Williams died, following a stroke, on December 16, 1967, in Chula VIsta, California. He was preceded in death by his wife, Louisa Lewis (Clark) Williams, who died in 1965. ” [James, Matthew S. Collecting Evolution, (2017)].
