Saidye Rosner Bronfman (1896-1995) was a prominent Canadian philanthropist, community leader, and wife of Samuel Bronfman. Born on December 9, 1896, in Plum Coulee, Manitoba, she was a first-generation Canadian of Jewish descent. She married Samuel Bronfman in 1922, who later built the Seagram Company into a major distilling empire. The couple moved to Montreal in 1924, where Saidye became deeply involved in philanthropic activities, actively supporting Jewish causes, community building, arts, education, women's welfare, and charities. She served as president of Montreal's Young Women's Hebrew Association starting in 1929 and was recognized for her wartime contributions to the Red Cross during World War II, earning the Order of the British Empire (OBE). She played a key role in the Canadian Jewish Congress through her husband's leadership and continued the family's legacy of community building. Her efforts extended to supporting the performing arts, with the Saidye Bronfman Centre for the Arts in Montreal named in her honor (later renamed the Segal Centre). Saidye passed away on July 6, 1995, at the age of 98, leaving a lasting impact on Canadian philanthropy and Jewish communal life.
