David Lewis, Grand Father
David Lewis CC QC (born David Losz; June 23 or October 1909 May 23, 1981) was a Canadian labour lawyer and social democratic politician. He was national secretary of the Co-operative Commonwealth Federation (CCF) from 1936 to 1950 and one of the key architects of the New Democratic Party (NDP) in 1961. In 1962, he was elected as the Member of Parliament (MP), in the House of Commons of Canada, for York South. While an MP, he was elected the NDP's national leader and served from 1971 until 1975.
Lewis's politics were heavily influenced by the Jewish Labour Bund, which contributed to his support of parliamentary democracy. He was an avowed anti-communist, and while a Rhodes Scholar prevented communist domination of the Oxford University Labour Club. In Canada, he played a major role in removing communist influence from the labour movement.
In the CCF, he took the role of disciplinarian and dealt with internal organizational problems. He helped draft the Winnipeg Declaration, which moderated the CCF's economic policies to include acceptance of capitalism, albeit subject to stringent government regulation. As the United Steelworkers of America (USW)'s legal counsel in Canada, he helped them take over the International Union of Mine, Mill, and Smelter Workers (Mine-Mill). His involvement with the USW also led to a central role in the creation of the Canadian Labour Congress in 1956.
