Career
Martin was one of the most notable of the impossibilists in the Social Democratic Federation (being expelled in April 1904), and helped found the Socialist Party of Great Britain later that year. He rejoined the Party on 6 November 1906 and left again, only to rejoin on 19 June 1908. He was then a speaker for the Party (1909–1911), an Executive Committee member (1911) and briefly Lambeth branch secretary (1911) before finally resigning over the World Bank of Upton Park affair in 1911.
He died early in 1951, aged 87.
