Leo Millard Holub (25 November 1916 – 28 April 2010) was an American photographer famous for his landscapes and architectural images of San Francisco, and photographs of Yosemite. His contemporaries and close friends included Ansel Adams and Imogen Cunningham.
Holub was born on a bee farm in Decatur, Arkansas, was a toddler in Oklahoma, and later moved with his family to Dawson, New Mexico, and then to Oakland, California where he attended elementary through high school. He worked as a printer’s devil in Oakland and in the Grass Valley gold mines as a blacksmith’s helper to raise money for his education. In 1935, Holub left California to attend the Art Institute of Chicago, which in 2011 awarded him a posthumous Honorary Bachelor of Fine Arts. After just one year, he returned to the West Coast to study at the California School of Fine Arts (presently known as the San Francisco Art Institute) where he was inspired to pursue photography.
