Streetlife on or near Telegraph Avenue, Berkeley, California (1971) Nick DeWolf Entrepreneur Nick DeWolf was an avid photographer who captured unique images of daily life in San Francisco in the summer of 1971.

His extensive collection of photos features the counterculture movement in Berkeley, the red light district in North Beach, the street scene on Telegraph Ave and many other images from various parts of the Bay Area.

An MIT graduate, DeWolf co-founded Teradyne, a manufacturer of automatic test equipment, in 1960 and designed a computer system without hard disks or fans captured in the 1970s.

We are featuring a selection of DeWolf's gallery of vintage San Francisco photos, courtesy of his wife Maggie DeWolf.
