Hedrich Blessing Photographers (also Hedrich-Blessing) was an architectural photography firm established in Chicago in 1929 by partners Ken Hedrich and Henry Blessing.[1] The Chicago History Museum houses the archive of the first 50 years of photography (1929–1979), where it is available for viewing by the public.[2] Hedrich Blessing collaborated with architects and designers both nationally and internationally[3] but also undertook non-architectural work; industrial, product, editorial, and corporate photography.[4]
