If you watch birds in southeast Pennsylvania or New Jersey, chances are you have heard of Witmer Stone (1866–1939), naturalist, historian of science, co-founder of the Delaware Valley Ornithological Club (DVOC) and first editor of its journal Cassinia. Among other accomplishments, Stone was also President of the American Ornithologists’ Union (AOU) from 1920–23 and Editor of its journal The Auk from 1912–36. He played a critical role in restoring the bird collection of the Academy of Natural Sciences of Philadelphia during the 1890s, after it had been neglected for years following the death of John Cassin (1813–69), and he added to the collection by joining Academy expeditions to Bermuda, Cuba, and Mexico, among other places.
Recently, I was elected to Stone’s old position, Editor of the DVOC and Cassinia, and I have been using data from Stone’s bird collections in my research at the Academy. A few months ago, while rummaging through a box of old items that were going to be discarded, I found and saved a treasure—an autographed reprint of Stone’s 1890 article ‘Birds collected in Yucatan and southern Mexico’, from the Proceedings of the Academy of Natural Sciences of Philadelphia. At the top of the pamphlet reads “Mr Serrill with the compliments of Witmer Stone”. Evidently the reprint was a gift from Stone to William J. Serrill (?–1952), who had joined the DVOC in 1891 and was an active member (and later Fellow) of the club for 61 years.
In early 1890, Stone accompanied malacologist Frank C. Baker (1867–1942) and geologist Angelo Heilprin (1853–1907) on an Academy expedition to the Yucatan, by way of Cuba. Stone was a young man—24 years old—just beginning his scientific career. Incidentally, I was the same age (23-24) when I joined my first field expedition, to study manakins (Manacus spp.) in western Panama with Adam Stein, so I can empathize a bit with Stone at this period of his life. He must have been very excited when this paper came out in the Proceedings. The ornithological community of Philadelphia was in the midst of a Renaissance, largely due to Stone’s prolific energy—the DVOC was founded that same year, and Stone mobilized a crew of birders to monitor the spring and fall migrations at multiple sites around the city. I think that Stone would be proud that today we are continuing his legacy of citizen science, and that the DVOC is still a thriving organization where professional and avocational ornithologists mingle to celebrate and share their mutual passion for birds. Happy birthday Dr. Stone — your legacy continues!
