Stewart Mittnacht Jr. ’74

Stewart died Jan. 23, 2026.  

He came to Princeton from Chestnut Hill Academy and after graduation attended Duke Business School. He had a long career in the pharmaceutical industry, primarily working in regulatory compliance. His most recent job was with Rhone Poulenc. After retirement, Stewart threw himself into The Savoy Company, where he was on the board and quarterbacked the backstage operation. He gave classmates a lively tour of the backstage during a recent class trip at Longwood Gardens.  

Stewart recently met a woman at a Super Bowl party who grew up very near him, but they had somehow never met. He and Anne O’Connell quickly realized they were in love and married last December. Prior, he had married Lisa Asche Mittnacht with whom he had two sons, Stewart III and Sanderson. He later married a high school sweetheart, Mary Shoemaker Mittnacht, who passed away after they lived in Santa Fe. Stewart was a frequent participant at class events and continued taking courses at Princeton.  

Stewart is survived by his wife, Anne; his two sons; grandchildren Charlotte, Madison, and Frederick; and his first wife, Lisa Anne. Services were held Feb. 28 at St. Paul’s in Chestnut Hill with attendees asked to wear orange for his love of Princeton.
