John Tyberg was born in Grantsburg, WI, USA on May 4, 1938. He died in Calgary, Alberta,
Canada on April 10, 2022 after a brief illness. John obtained a PhD in 1967 and an
MD in 1972, both from the University of Minnesota, and did post-doctoral studies at
Harvard and Peter Bent Brigham Hospital. He subsequently worked at the Cedars-Sinai
Medical Centre in Los Angeles and the Cardiovascular Research Institute at the University
of California (San Francisco), before moving to the University of Calgary in 1981
as Professor in the Departments of Cardiac Sciences and Physiology & Biophysics. He
was subsequently appointed as a Scientist of the Alberta Heritage Foundation for Medical
Research, an appointment he held for more than 20 years. He is survived by his wife,
Dr. Naomi Anderson, his daughter Anna de Tombe, two grandsons, Philip and Jack de
Tombe (of whom he was very proud) and two brothers, Rodney and James Tyberg. John
was a quiet, humble man who obtained great joy from mentoring his students and Fellows,
and from his love for literature, history and music.
