Born in Chicago, John built a career in animal sciences that carried him through Argonne National Laboratory, the University of Nebraska, and G.D. Searle (later Pfizer Pharmaceuticals). Few creatures, large or small, escaped his gentle care, a devotion he carried into volunteer work at Lincoln Park Zoo and the Lincoln (Neb.) Children's Zoo. He loved to tell of the ailing Bengal tiger he helped treat on his second date with Beth, who took notes as he worked, a story that became family legend.

Storytelling was John's second calling. A natural folk-teller and the family's devoted genealogist, he could turn any afternoon into an adventure, weaving family history and tall tales with equal delight. He was, above all, a human joke-telling machine, a bottomless well of humor and mischief that made it nearly impossible to think of him without breaking into a smile, or a groan, at some remembered bit of comedy.

Each December, John became Santa's most devoted helper, filling in at community Christmas parties and Operation Christmas Telethons, and delighting neighborhood children with surprise early visits from Santa himself. John’s "magic" paper bag and mysterious colored balls baffled generations of nieces, nephews, and children who never quite figured out his tricks.

John was a gentle gentleman who lived to help, to laugh, and to love. He will be deeply missed.
