Sabidussi was born in
Graz, Austria, on 28 October 1929. His family later moved to
Innsbruck, where his father was a Protestant
deacon. He graduated from the
University of Vienna, where he attended lectures by
Felix Ehrenhaft,
Nikolaus Hofreiter,
Johann Radon and
Hans Thirring. In 1953, he defended his
doctorate on
0–1 matrices under the supervision of
Edmund Hlawka and received a two-year fellowship at
Princeton University. He was then an instructor at the
University of Minnesota in
Minneapolis, but because of the heavy teaching load moved a year later, in 1956, to
Tulane University in
New Orleans. He moved to
McMaster University in
Hamilton, Ontario, in 1960 and afterwards to the
University of Montreal in 1969. He was instrumental in bringing to Canada a number of combinatorialists and graph theorists, including
Anton Kotzig and
Jaroslav Nešetřil, who wrote a thesis under Sabidussi. Over the years, he had 13 graduate students. His 60th, 70th and 80th birthdays were celebrated with large graph theory birthday conferences. Sabidussi died on 1 April 2022, at the age of 92. == Mathematical work==
