About This Collection
The digitized papers of Charles J. Pennock consist of a small number of letters, most by or addressed to Charles J. Pennock; two bird log books; a manuscript copy of a bird book by Charles L. Bonaparte; and a notebook of geology notes. Materials date from 1791 to 1927, with the bulk of the collection dating from 1860 to 1927. Charles John Pennock was an ornithologist who lived most of his life in Kennett Square, Chester County, Pennsylvania. Pennock was born to a Quaker family in 1857, the son of Deborah Yerkes and Samuel Pennock. He was married twice, and had two sons and two daughters. He was a tax collector, magistrate, and businessman in Kennett Square, but his chief love was for birds. Pennock collected specimens and took notes on the birds he spotted around Chester County. He was a member of the Delaware Valley Ornithological Club, serving as president 1901-1903; the American Ornithologists’ Union (A.O.U.); and the West Chester Bird Club. He also studied birds in Delaware and was named its state ornithologist. He amassed a significant collection of books about North American birds, and his collection of birds and eggs was given to the Philadelphia Academy of Natural Sciences. After attending an ornithological meeting in Philadelphia on May 15, 1913, Pennock did not return home. Police were alerted and a search for him was instigated, but he was not located. However, in 1919, Dr. Witmer Stone, curator of the Philadelphia Academy of Natural Sciences, believed that notes various ornithologists were receiving from a John Williams in St. Marks, Florida were similar to notes Pennock had written. Stone’s suspicions were enough aroused that he alerted one of Pennock’s relatives, Dr. Richard J. Phillips. Phillips journeyed to St. Marks to investigate and discovered that John Williams was indeed Pennock. With his identity discovered, Pennock returned to his wife in Kennett Square and died there in 1935.
