Shidler, Jon Keith

Jon Keith Shidler passed peacefully at St. Francis Hospital in Wilmington, Delaware on Saturday morning, January 12, 2019 with family at his side. He was 79 years old, and had fought congestive heart failure for many years. He is survived by his son Jon Edwin (Jed) Shidler of Wilmington, and his daughter Lieschen Fish, son-in-law Bradford Fish, and four grandchildren, Caitlin, Emily, Jacob, and James Fish of Chadds Ford, Pennsylvania. Another daughter, Gaia Nunnelee Shidler, predeceased him. He is also survived by his ex-wife Elizabeth (E-Bette) Shidler of Hockessin, his sister-in-law Miriam (Mimi) McKay of Lorain Ohio, and seven nieces and nephews and their families.

Jon was born and raised in Ashland, Ohio, son of Jay Harold Shidler and Florence Marie Baker Shidler. He earned a bachelors degree in biology at the College of William and Mary, where he met E-Bette and got married. Jon followed a varied career path, with stints as a marine biologist/oceanographer on the Chesapeake Bay and at the Texas Fish and Games Commission near Houston, and as a computer systems analyst at IBM in Massachusetts, and at Atlas Chemicals in Wilmington, followed by various independent consulting jobs as a computer systems analyst and technical writer, which took him to New York City, New Jersey, Virginia, Puerto Rico, Saudi Arabia, Pennsylvania, and back to Wilmington.

In his spare time, Jon was a voracious reader and an adventurer: he enjoyed spending time at the rustic cabin he built in his teens, on an island in the Georgian Bay, Lake Huron, Ontario, Canada. He loved the outdoors, camping, hiking, and canoeing. He was an avid birdwatcher and shell collector, specializing in the genus Murex. Upon retirement, Jon pursued in-depth genealogical research of his family (and others) and compiled a great deal of information about the lives of his ancestors, who he was able to track as far back as the 16th century. He created and populated a comprehensive website for his grandchildren to track their ancestry (
