Rosenberg, Louis, 1893-1987 : Louis Rosenberg was born in Gonenz, Poland and was taken to England by his parents at the age of 2 years. He was educated at the University of Leeds and upon graduation immigrated to western Canada in 1915 where he became principal of the Tiferes Israel School in Lipton, Saskatchewan, a community of Jewish farm colonist. From 1919 until 1940 Rosenberg was the western Canadian director of the Jewish Colonization Association in Winnipeg which had its headquarters in Paris, France. In 1940 he became executive director, Western Division of the Canadian Jewish Congress in Winnipeg, and in 1945, was appointed national research director of the Bureau of Social and Economic Research of the Congress in Montreal, a position from which he retired in June 1968.
Throughout his life Rosenberg took an active part in community affairs: as a scoutmaster in England, as chairman of the Regina Public School Board and of the Regina Public Library, and as an active participant in Jewish community organizations, in particular the Canadian Jewish Congress. A proponent of social democracy, Rosenberg was one of the founders of the C.C.F. and was one of their pamphleteers and speakers. Perhaps most noted in this respect was his series of articles "Who Owns Canada" under the pseudonym "What Hugh McCollum". In his research and writing Rosenberg concentrated on statistics and sociology. As research director at the C.J.C. he published a series of statistical and demographic studies of the Jewish community in Canada.
