Michael Robert Marrus CM FRHistS FRSC (February 3, 1941 – December 23, 2022) was a Canadian historian of the Holocaust, modern European and Jewish history and international humanitarian law.
Marrus was Professor of History and Dean of Graduate Studies at the University of Toronto and served for nineteen years as Governor of the institution.
In it, Marrus denies there can be any definitive set of lessons to be learned from the destruction of the European Jews and instead affirms that there are many ever-evolving questions that need to be continually studied and re-interpreted.
In October 1999 Marrus was one of three Jewish scholars appointed to the International Catholic-Jewish Historical Commission to investigate the role of the Pope Pius XII during the Holocaust.
The commission was supposed to review and discuss the previously published Vatican records pertaining to the World War II period and report on their assessment.
In an interview in the Jerusalem Post Marrus expressed regret that the commission had run "up against a brick wall" on the question of opening Vatican archives.
