Alan L. Schneyer, 66, of Concord, passed away on November 18, 2020. Born in Philadelphia, Pennsylvania on July 12, 1954, he was the son of the late J. Wesley and Irma Schneyer. After completing his studies at Central High School in Philadelphia and the University of Pennsylvania, Alan earned a PhD in Marine Biology from the University of Miami. Among his many professional achievements, Alan was most proud of the research he conducted during his twenty years in the Reproductive Endocrine Unit at Massachusetts General Hospital. After another 10 years at the University of Massachusetts, Amherst and Pioneer Valley Life Science Institute, his career took a new path when he founded a startup working on a therapy to cure diabetes. Alan was a longtime and active member of the Federation of American Societies for Experimental Biology (FASEB) and the Endocrine Society, most recently spearheading efforts to open entrepreneurial opportunities to young researchers. Alan was an innovative scientist, a caring mentor, a willing collaborator, and a truly bold entrepreneur. Alan was a regular at the Beede fitness center, a hiker, a biker, a sailor, and a frequent presence on the pickleball court. In addition to his wife, Elissa Brown, of 36 years, he leaves behind two children, Jon and Becca Schneyer, both of Boston, a sister, Barbara Engel and her husband Bruce of Northport, NY, a brother, Mark Schneyer and his wife Debbie Field of Ann Arbor, MI, as well as several nieces and nephews. He was also the brother of the late Fred Schneyer. A celebration of Alan's life will be planned at a later date. In lieu of flowers, contributions in his memory may be made to American Diabetes Association, P.O. Box 7023, Merrifield, VA 22116 (www.diabetes.org). Arrangements are under the care of Dee Funeral Home & Cremation Service of Concord.
