My brother Patrick Renshaw, who has died aged 87, was a noted historian of American politics and labour. He produced a major study of a significant British event, the General Strike of 1926, whose publication coincided with its 50th anniversary. Other notable volumes include American Labor and Consensus Capitalism, 1935-1990 (1991), and, perhaps the finest work of his career, a study of Franklin D Roosevelt (2004).
He wrote on Alexis de Tocqueville and produced the Longman Companion to America, 1910-1945, and many journal articles. For several periods he worked in US universities, which he especially enjoyed.
