John Costain (Jack) Knight II, 81, passed away on September 5, 2017. He attained both his Bachelor's degree in Science and his PhD in Organic Chemistry from the University of Liverpool, and in 1960 moved to the United States to begin a post-doctoral fellowship at the University of Maine. Jack's research on steroids and other bioactive chemicals moved him across the United States: first to Stanford University, where he did a year-long post-doctoral fellowship, then to the Argonne National Laboratory outside of Chicago, to ASU, and eventually to The Upjohn Company in Kalamazoo, Michigan. In 1997 he retired from Upjohn and returned to Arizona and to ASU as an associate professor.  He continued his anti-cancer research and ran the university's Mass Spectrometry Facility under his friend and mentor, Bob Pettit, until his retirement in 2006. Jack is survived by his wife, Sandra (Sandy) Blaisdell, a daughter, a son and three grandchildren. His family and friends gathered on September 15 to pay tribute to his life and honor his memory in Kalamazoo, Michigan, at Old Burdick's Bar and Grill in Downtown Kalamazoo. Donations may be made to cancer research. (Source: ASU Foundation)
