John was raised in the west side suburbs of Cleveland, Ohio spending various amounts of time living in apartments in Cleveland, Lakewood, Westlake, and Rocky River before the family settled into a house in Lakewood while he was in the 6th grade. His parents loved fishing and he obtained his passion for the outdoors from the many family fishing trips. He would usually fish for a few hours and then sneaked off to catch turtles, frogs, or salamanders. Squirrels were one of the few species that could be found in an inner, highly urbanized, suburb and became a fascination for the young naturalist; the taxonomic group remained a research interest in his career. He had become fascinated by questions about animal behavior and how animals were able to survive in such challenging environments. Besides biology, John had strong interests in sports, especially baseball, and history; he coauthored a history of the Lakewood, Ohio public school system while a student in Advanced Placement U.S. History at Lakewood High School that was integrated into the curriculum. As a high school student, John was a member of the Latin Club, The Wilderness Society, and the Backpacking and Mountaineering Society that permitted him to combine his interests in science and the outdoors.
