Henry Stanford Diltz (born September 6, 1938, in Kansas City, Missouri) is an American folk musician and photographer who has been active since the 1960s.
Among the bands Diltz played with was the Modern Folk Quartet. While a member of the Modern Folk Quartet, Diltz became interested in photography, met The Monkees, played on some of their recording sessions, and took numerous photographs of the band, many of which have been published. His work also attracted the eye of other musicians who needed publicity and album cover photos. He was the official photographer at Woodstock, and the Monterey and Miami Music Festivals, and has photographed over 200 record album covers.
