OBITUARY: DAVID HERMAN MacLENNAN PhD, FRSC, FRS, OC, OOnt July 3, 1937 - June 24, 2020 David MacLennan, beloved son of the late Douglas MacLennan and the late Sigriour Siguroardóttir, passed away peacefully with family at his side. Predeceased by his beloved wife Linda, and daughter Jessica, David will be greatly missed by his sons, Jeremy and Jonathan; his much-loved niece, Lori; his siblings - Winona, Marilyn, Greg and May; and his numerous colleagues and friends. One of Canada's outstanding scientists, David earned an international reputation for his work on the regulation of calcium in muscle and the genetic basis for diseases that affect this process. For his tireless efforts and dedication, he was the recipient of numerous prestigious awards, including Officer of the Order of Canada, Fellow of the Royal Society of London, and Foreign Associate of the U.S. National Academy of Sciences. Donations in David's memory may be made to the Muscular Dystrophy Foundation or the charity of your choice. Condolences may be forwarded through www.humphreymiles.com

1: David MacLennan From Wikipedia, the free encyclopedia David MacLennan Born July 3, 1937 Swan River, Manitoba, Canada Died June 24, 2020 (aged 82) Toronto, Ontario, Canada Nationality Canadian Education University of Manitoba (B.S.A.) Purdue University (M.S., Ph.D.) Scientific career Fields Biochemistry, Genetics Institutions University of Toronto Thesis Compartmentation of organic acids in plant tissues (1963) Doctoral advisor Harry Beevers David Herman MacLennan OC OOnt FRS FRSC (July 3, 1937 - June 24, 2020) was a Canadian biochemist and geneticist known for his basic work on proteins that regulate calcium flux through the sarcoplasmic reticulum (SR), thereby regulating muscle contraction and relaxation, and for his discoveries in the field of muscle diseases caused by genetic defects in calcium regulatory proteins.
Born in Swan River, Manitoba, to Douglas MacLennan and Sigriður Sigurðardóttir, he received a BSA from the University of Manitoba in 1959 and a DSc (hc) in 2001. He received MS (1961) and PhD (1963) degrees from Purdue University under Harry Beevers, and was then a Postdoctoral Fellow (1963-1964) under David E. Green and an Assistant Professor (1964-1968) at the University of Wisconsin–Madison. In 1969, he was appointed Associate Professor in the Banting and Best Department of Medical Research and, later, Professor (1974), Chair (1978-1990), J. W. Billes Professor of Medical Research (1987-2007) and University Professor (1993-2015).
MacLennan made fundamental contributions to our understanding of the mechanism of ion transport by SR calcium pumps, the storage of calcium in the SR by acidic lumenal proteins and the release of calcium from the SR by calcium release channels. He led teams that defined the genetic basis for the human skeletal muscle diseases, malignant hyperthermia, central core disease and Brody disease and was part of the team that demonstrated that mutations in phospholamban, a regulator of the calcium pump, can cause cardiomyopathy. His identification of a calcium release channel mutation that causes porcine stress syndrome resulted in a diagnostic test that has decreased the incidence of the disease dramatically, with substantial economic benefits to the swine industry.
