About this photograph
A glass plate negative taken by commercial photographer Theodor Horydczak in 1920. The record identifies it as a copy photograph of a military cadet, meaning Horydczak reproduced an existing image rather than photographing the subject directly.
Horydczak worked in Washington, D.C., and his photographs are held by the Library of Congress as a named collection. The timing places this image shortly after the First World War, when military training remained prominent in American life. Copy work formed part of the commercial photography trade, preserving or duplicating portraits for clients.
The 5 by 7 inch glass negative was a standard professional format of the period, offering detail and durability for making prints. No information survives about the cadet's identity, the original photograph's source, or who commissioned the copy.
Compiled from the catalogue record and reference notes on the formats and events involved. The archive record above is the primary source.
