Born in 1910 in London of a Jewish immigrant family, Bill Sedley became a graduate in economics and law. He operated a legal advice service in the East End of London in the 1930s. Sedley was especially known for his defence of tenants’ rights in 1938-9 and for providing support for squatters’ rights and mortgage strikes after the war.
He founded the firm of lawyers of Seifert and Sedley in the 1940s with Sigmund Seifert and was a life-long Communist and supporter of the Morning Star even until his last days; he died in 1985.
