Joseph A. Smith (1895-1978) was an avid collector of railroad photos, sharing many of them with fellow collectors in the Northeast. A former plumbing contractor, he presumably developed his interest in railroads through his father James H. Smith, a trolley motorman in Troy, NY. His extensive collection focused on the lines that once served Troy: Delaware & Hudson, Rutland, Boston & Maine and New York Central.
