Clint Dumm at one time worked as a photo finisher at Yocom Studios. He evidently devoted a significant part of his life to taking these photographs and indexing them. He created two indexes: a consecutive index by photograph number, and an alphabetical index of subjects. He stored the photonegatives in custom-printed envelopes that fit in a large custom-made wooden cabinet along with the indexes.
Clint Otis Dumm was a Boulder native. He was a member of the First Methodist Church since 1903. Dumm worked as a bus driver, stone cutter, chauffeur and at various other jobs. Active in scouting, he helped organize Boy Scout Troop No. 71, of which he was the scoutmaster from 1925 to 1938. Dumm was an officer of the State Board of Child and Animal Protection from 1913 to 1963, and was a member of the Boulder Historical Society.
