Arnis Kuksis

Born Dec. 3, 1927, in Valka, Latvia, Kuksis chose to pursue higher education in North America; after arriving in the United States with the support of a Lutheran World Federation Scholarship, he earned bachelor and master of science degrees from Iowa State University and a Ph.D. in biochemistry from Queen's University in Kingston, Ontario in 1956. He remained in Ontario for his postdoctoral studies at the Royal Military College, then returned to Queen's to join J.M.R. Beveridge’s lab as a research associate in lipid biochemistry. 

After he was promoted to assistant professor of biochemistry at Queen’s, Kuksis' research focused on the analysis and characterization of triglycerides and phospholipids. He pioneered the use of high-temperature gas chromatography to resolve molecular species of triglycerides from natural fats and oils, a technique that became a standard in lipid research. His work extended to steryl esters and glycerophospholipids, enhancing the understanding of lipid structures and their metabolic pathways.

Kuksis authored numerous publications that had a significant impact on  the field of lipid biochemistry. His research on the metabolism of molecular species of diacylglycerophospholipids and the lipid analysis of glycoinositol phospholipid membrane anchors are among some of his most cited works. He authored or co-authored over 370 original articles, 100 invited reviews and book chapters, and he wrote the book "Inositol Phospholipid Metabolism and Phosphatidyl Inositol Kinases."  He edited or co-edited six books.

Kuksis served as a career investigator for the Medical Research Council of Canada from 1960 to 1997 and was the director of the MRC Regional Mass Spectrometry Facility at the Banting and Best Department of Medical Research, University of Toronto, from 1972 to 1997. In 1997, he was named professor emeritus at the University of Toronto.

In addition to his research, Kuksis was a dedicated mentor, supervising numerous doctoral and master's students and postdoctoral fellows.

Kuksis was preceded in death by his wife of more than 70 years, Inese, and his son Lauris. He is survived by his children Anda, Davis and Inga; seven grandchildren, and six great-grandchildren.  

His family wrote in an , “Our father was a stoic, modest man, a counsellor, coach, poet and role model. He will be remembered for his humour, generosity and guidance.”
