Jean died peacefully in her home with family present on the night of July 20, 2015. Born and raised in Kalamazoo, Jean earned her B.A. from K in biology. Later, while attending the University of Michigan’s summer graduate biology program at Douglas Lake, she met Nathan (Pete) Riser, her future husband. After completing her M.A. (zoology) at the University of Wisconsin-Madison, she studied and became a certified medical technologist at Bronson Hospital in Kalamazoo. During World War II she worked in a pathology lab near Lansing, Michigan. Her enthusiasm for that work was evident in her stories and detailed knowledge of pathogens. Before moving to Damariscotta, Maine, Jean spent more than 50 years in the Boston area, as a hospital pathology lab volunteer, a college anatomy instructor, a Girl Scout troop leader, a conservation advocate and a docent at the Peabody-Essex Museum of Salem, Mass. She was a lifelong learner, an avid naturalist, birder, photographer and hiker. Past 90, she was still able to walk two miles and to enjoy identifying fauna and flora. Jean was a world traveler, who took great pleasure in attending international scientific meetings with her husband. She also enjoyed living in New Brunswick and in New Zealand during sabbatical years, as well as participating in an East African ornithological safari and a South Seas sailing adventure. Throughout her life Jean maintained detailed records of natural history, family health, travel and other events of interest. In addition, she possessed encyclopedic knowledge on a great variety of topics from Asian art to Wagnerian opera to European history to scientific discoveries. Her daughter once said, “She was Google before Google.” Several of Jean’s relatives have K connections. Her mother Ruth Desenberg Folz attended K for a year. Jean’s first cousin, Samuel Folz, was a member of the class of 1947. And Jean’s daughter Claire graduated in 1967. Jean was predeceased by her husband and is survived by her three children, six grandchildren and four great-grandchildren.
