In the early 20th century, the St. Louis Street Department generated one of the most extensive troves of photographs ever taken of the city. Ostensibly created to document municipal challenges and improvements, the images inadvertently captured richly detailed scenes of everyday life. Largely led by Charles Clement Holt, St. Louis’s photography operation expanded until it was producing about 6,000 images per year by 1914. Many of these photos were lost, but a city historian salvaged a collection of 300 glass-plate negatives in the 1950s, which are now in the Missouri Historical Society collections. Join authors Joseph Heathcott and Angela Dietz as they examine these photographs.
