Series 13: Photographs, 1924-1991

This series contains photos documenting Welch's life, most of which were included in the Festschrift volume. Here also are photgraphs documenting the transfer of the DePauw and Wabash College herbariums to NYBG. Other photos are a series of views of the Grand Canyon probably purchased in 1931. Negatives have been removed and are found in the negative series.
