Edward Henry Vidruk (1939-2022). Ed was a native Canadian from Winnipeg who received his university education in the US, culminating in a PhD in neurophysiology in 1973 at UW-Madison, followed by a post-doctoral fellowship at the Cardiovascular Research Institute in San Francisco. Ed then served 25 years as an NIH funded, tenured professor in the Dept of Population Health Sciences. As an integral member of the Rankin Laboratory of Pulmonary Medicine, Ed researched the plasticity of neural networks controlling breathing, the effects of sleep states on the neural control of breathing, and the nervous innervation of airway smooth muscle. He was a key team member responsible for the mentoring of several pre- and post-doctoral trainees. Ed’s quiet yet wise, insightful reassuring presence will be missed. He is survived by his wife Janice of 58 years, two children and six grandchildren.
