Clackamas County Historical Society was formed in 1952 when residents of Oregon City and surrounding cities met to collect and preserve artifacts from the county. Founding members Wilmer Gardner and Mertie Stevens, along with many others, collected photographs and negatives from local sources. This collection of over 4,000 images was the beginning of what is now a photograph collection estimated to have over 50,000 images. All images used in this book are from the society's collection.
