Jon Eric Mendelson 1940 - 2014

Jon-HowToPlantGarlic05Two roads diverged in a wood, and he — he took the one less traveled by, 
And that has made all the difference.


Jon Eric Mendelson. Born 1940, New York City, died Nov. 22, 2014 at home, peacefully, surrounded by family. Emeritus Professor of Environmental Biology at Governors State University, Chair of Thorn Creek Nature Preserve Management Commission, field ecologist, land preservationist, musician, beloved husband, father, grandfather, teacher, and friend. He worked tirelessly to acquire land for Thorn Creek Woods and to protect local watersheds, taught courses in ecology to generations of students, played blues and folk with the Moose River Band, grew garlic for Thorn Creek’s Garlic Fest, and fashioned mobiles out of gourds for his grandchildren. Survived by his loving wife, Judith Dolan Mendelson, three children, Nina (Riyaz Kanji), Robin (Joss Delage), Claudia (Josh Pincus), and five grandchildren, Laura and Evan Kanji, Miles Mendelson-Delage, Celia and Oliver Pincus. He will be greatly missed. In lieu of flowers, donations may be made to the Friends of Thorn Creek Woods, P.O. Box 1589, Richton Park, IL 60471.

There will be a memorial celebration in his honor at a later date. If you wish to send cards or letters to Judy and the family: Judy Mendelson and Family, 24300 Western Avenue, Park Forest, IL 60466,
