Gilbert died Oct. 25, two days after celebrating Mole Day. While at Queen’s, Gilbert’s sister, Mary, set him up on a blind date with Ardeth Justus, Arts’52. They married in 1956. In 1965, Gilbert began his career as a clinical biochemist at the Hospital for Sick Children in Toronto. He was a pioneer in laboratory automation and became biochemist-in-chief. He simultaneously rose through the academic ranks at the University of Toronto in what is now the Department of Laboratory Medicine and Pathobiology. He was recognized with a lifetime honorary membership in the Canadian Society of Clinical Chemists in 2011. Gilbert retired from SickKids in 1995 and took on a second career in medical informatics. Gilbert was an advocate for conservation and an enthusiastic naturalist. His kindness, sincerity, integrity, and calm presence made him an excellent teacher and mentor, and the best father that anyone could hope for. Gilbert was predeceased by his brother Donald, BASc’50. He is survived by his wife, Ardeth; his children Margaret, Janet, Artsci’90, PhD’95 (David Palmer, Artsci’89, PhD’95), and Andrew, Sc’91; his younger sister Mary Summerby, Meds’55; and many nieces and nephews.
