Jim was born on August 27, 1927, to Alex and Annie Elizabeth Catherine (née MacKay) McCorquodale in Winnipeg, and grew up in Victoria. He worked a year as a chemist with British American Paint Company (BAPCO) in Victoria, and went on to earn a PhD in biochemistry from the University of Wisconsin‑Madison. He then held a post‑doctoral fellowship at the Max Planck Institute in Munich and spent the rest of his career as a professor of biochemistry. He made notable research contributions in biochemistry, cytogenetics and virology at the Massachusetts Institute of Technology, Emory University, the University of Texas at Dallas, the Medical College of Ohio in Toledo, the Northwestern Memorial and Michael Reese Hospitals in Chicago, and Midwestern University in Oak Brook, IL. He taught courses in medical school curricula and was research advisor to numerous graduate students who went on to make their own contributions to science. He fondly appreciated the fine arts as both a baritone and trombone player, and a self‑taught piano player. He enjoyed travelling, practicing his German, nature, poetry, gardening, bike riding, football, golf, stimulating conversations, fine dining, bridge, square dancing and taking long walks with his family. His loving family will dearly miss his unwavering love, patience, support and wisdom.
