Dr. James Stone Widder

James (Jim) Stone Widder, Ph.D., age 90, passed away peacefully on Sunday, September 28, 2025, surrounded by his family after a long and courageous battle with Parkinson's Disease. Born on February 28, 1935, to the late Milton and Dorothy (née Stone) Widder, Jim was a devoted husband to the late Susan (née Schwartz) Widder, and a loving father to Deborah "Debbie" (José) Marques and Karen (Kent Cleland) Widder. He was the beloved grandfather of Nicolas Marques, Dylan Marques, Larkin Cleland, and Chloe Cleland. He is also survived by his sister, Barbara (John) Beazle, and was preceded in death by his brothers, John Widder and Robert Widder. Jim was a proud graduate of The Ohio State University, where he earned a B.S. in Biological Sciences, an M.S. in Immunology, and a Ph.D. in Molecular Biology. He went on to complete postdoctoral work at the Pasteur Institute in Paris. In 1962, Jim began a distinguished career at The Procter & Gamble Company, while also teaching at the University of Cincinnati College of Medicine. A dedicated scientist and educator, he was credited with more than 45 patents and publications throughout his career. In 1968, Jim and Susan discovered a shared passion for antiques, becoming well known within the Midwest antiques community and forming lasting friendships along the way. In retirement, they traveled extensively-visiting South Africa, Tanzania, Botswana, the Amazon, China, Alaska, and many parts of Europe. More than anything, Jim cherished spending time with his many friends and family. He found his greatest joy in being a grandfather and was happiest when surrounded by those he loved most. A celebration of life will be held on Sunday, October 5, at 11 a.m. at the Weil Kahn Funeral Home (8350 Cornell Rd., Cincinnati, OH 45249), with visitation beginning at 10 a.m. A private interment will take place at a later date. In lieu of flowers, memorial contributions may be made to Hospice of Cincinnati, 4360 Cooper Rd. Cincinnati, OH. 45242.
