Hand-signed black and white photograph of Dwight D Eisenhower, with accompanying plaque.

The Berkeley family of photographers -- Berkeley's grandfather, the late Peter Berkeley, his father Robert Berkeley (now retired) and Roy Berkeley -- began preserving history nearly 75 years ago in what originally was the Lainson photography studio anchored in the lobby of the Brown Palace Hotel. Renamed Berkeley Lainson Photography in 1973 when Roy joined the family business, the studio moved to its present location in LoDo at 1730 Wazee some eight years ago.
