A subcollection of the Wadsworth Family Papers, this includes thirty-three albums, and approximately 350 glass lantern slides, of photographs taken by Martha Blow Wadsworth (1864-1934) between 1890 and World War I. Many of the photographs depict family, friends, and scenes of the Genesee Valley, but some chronicle trips taken within the United States and to Alaska, Europe, and Panama during the time of the canal's construction.
A selection of the photographs can be found in the New York Heritage digital repository.
