Henry Augustus Pilsbry

234: 38: 283:. The large majority of his work carried only his name, although there were sometimes joint or junior authors, some of whom were more patron than scientist. It is notable that Pilsbry did not always confine himself to the several areas of study with which he was already closely associated, but rather would sometimes stray into other fields of science, from geology and paleontology to the taxonomy of 220:. This meeting led, within a few months, to Tryon's hiring Pilsbry as an assistant. He was, no doubt, impressed by the young man's talents as a proofreader, considerable expertise in technical illustration, and especially by his undeniable enthusiasm for the study of mollusks and substantial knowledge of the subject. 290:

His field work provided a steady supply of new specimens for study, dissection, and illustration, and a seemingly endless array of new species to name. Pilsbry named 5680 organisms; a full list was published in a 218-page volume. Pilsbry performed extensive amounts of field work, and was clearly an

For almost all of the next 57 years of his long life, Henry Pilsbry spent his hours writing scientific papers, over 3,000 of them, mostly while at the Academy of Natural Sciences. Most of his longest papers were published by the Academy. The shorter ones could usually be found in

Pilsbry suffered a heart attack in late 1957 while working at the Philadelphia Academy. He seemed to recover from this serious occurrence, but died at his winter home in Florida, about a month and a half later, from a similar event.

Less than three months after Pilsbry began his new job, George Tryon died and his new assistant, only 25 years old, perhaps to the surprise of some, inherited the titles of "Conservator of the Conchology Section" and "Editor" of the
