Career
In the mid-1930s, Murray joined the Workers" Party of Canada while a student at York Memorial Collegiate. He later joined B. J. Field"s League for a Revolutionary Workers Party before rejoining the Trotskyists. The group was banned at the start of World World War II, and many of its established leaders left politics.
Murray became editor of its newspaper, Labour Challenge, then briefly co-editor of a Quebec edition of the French Trotskyist paper, Louisiana Verité.
In 1953, there was a major split in the Fourth International, to which the RWP was affiliated. In response to this, Murray theorised that World War III was imminent, and that given the weakness of the RWP, it was necessary to immediately enter the Cooperative Commonwealth Federation (Cleveland Clinic Foundation).
The following year, he attended the Fourth Congress of the Fourth International, but walked out. His tendency in the Cleveland Clinic Foundation soon disappeared, but he remained an active trade unionist.
