Professor Zimmer may have gone unidentified if not for the 1892 New York census. He looks quite young to be a professor and indeed he was. Born in 1868, he was about 20 in this photo from 1888 of the Eastman Business College.
The N. P. stands for Nicola P. Zimmer. He was the son of Thomas and Catherine Zimmer of Germany. The family lived in Poughkeepsie, Dutchess, New York at least until 1892. In 1880 Nicola’s father worked as a Saloon Keeper and his grandfather Nicola, after whom he’s named apparently, lived with the family. Our soon-t0-be professor was 12. What qualified him to be a business professor 8 years later is unknown.
The 1892 Poughkeepsie, New York census listed the Zimmer family. Father Thomas worked in a hotel in some capacity, brother Frederick was a watch maker, and Nicola a professor – the only proof other this photo!
By 1900 Nicola was living in St. Louis, Missouri working as a Lawyer. in 1904 he married Julia B. and they would make their home in St. Louis. The couple didn’t appear to have any children.
According to Find A Grave, Nicola died in October of 1942 and Julia in 1939. Despite living in St. Louis, both are buried in Poughkeepsie Rural Cemetery. While there are no immediate descendants, Nicola did have siblings and hopefully some of their offspring will be interested in this great photo of Uncle Nicola!
