As more high-salaried tech workers move into San Francisco, the face of the city continues to evolve.

Photos taken in the 1940s and 1950s by amateur photographer Charles Cushman show a beautiful and diverse city, one that’s filled with gorgeous vistas, classic Victorian homes, and people from all walks of life.

The colorful photographs — among the first of their kind — are an amazing glimpse at a San Francisco of the not-so-distant past.

Cushman snapped this photo of his car on the Marin County side of the Golden Gate Bridge in 1938, one year after the bridge was completed. Cushman was an early user of Kodachrome, a revolutionary color film developed by Kodak in the 1930s.Charles W. Cushman Photograph Collection/Indiana University ArchivesCushman’s photos have an extremely bright quality to them. Color film was still in its elementary phases during the majority of his career.Charles W. Cushman Photograph Collection/Indiana University ArchivesHere, two women pose with the Bay Bridge.Charles W. Cushman Photograph Collection/Indiana University ArchivesIn 1939, San Francisco hosted the Golden Gate International Exposition to celebrate the official opening of the city’s two bridges. Engineers built a manmade island just for the occasion. Christened Treasure Island, the island was later redeveloped as a naval base and still exists today.Charles W.

Cushman’s collection shows a great diversity of life in San Francisco. Before it became an attraction for tourists, Fisherman’s Wharf was home base for immigrant Chinese and Italian workers, who would use small boats to catch crab and fish.Charles W.

Here, a California Street cable car stops for passengers at Grant Avenue in Chinatown.Charles W. Cushman Photograph Collection/Indiana University ArchivesCable cars were a hot topic in the ’40s and ’50s, as during that time many local politicians launched efforts to ban them from the streets. The cable cars still survive today thanks to the efforts of a citizen committee and an overwhelmingly positive citywide vote.Charles W. Cushman Photograph Collection/Indiana University Archives

Known as “the Russell House,” this architecturally stunning home was built by Erich Mendelsohn between 1947 and 1952. It still stands in Presidio Heights today, though the wires have since been installed underground. Cushman called it “the very last word in San Francisco dwellings.”Charles W.
