Hyacinth Bernard Wenceslaus Morgan (11 September 1885 – 7 May 1956) was a Labour Party politician in the United Kingdom. He was a Member of Parliament (MP) from 1929 to 1931, and 1940 to 1955.
He was born, of Irish descent, in Grenada, West Indies and came to the United Kingdom to study medicine at Glasgow University in 1904. While at University he was active in the Fabian Society and founded the students' Irish Nationalist Club. After qualifying, he worked in a number of Glasgow mental hospitals and then served as a doctor in the Royal Army Medical Corps during the First World War in both France and England. He then entered general practice in London, initially at Greenwich, later Camberwell and finally at Paddington.
However, the Labour Party split at the 1931 general election over fiscal policy; Prime Minister Ramsay MacDonald had left the party to form a National Government with the support of the Conservative Party and some Liberals, and Labour's national share of the vote fell from 37% to 31%.[1] In most seats, Liberal and Conservative candidates agreed a single candidate would stand against Labour. As a result Labour retained only 52 of the 287 constituencies it had won in 1929, and Morgan's Camberwell seat was one of the seats lost.
In the periods he was not serving as a Member Parliament, Morgan returned to the practice of medicine. In 1936 he worked with Charles Brook and other members of the Labour-affiliated Socialist Medical Association to found the Spanish Medical Aid Committee to provide supplies and a uniformed medical unit to the Republican side in the Spanish Civil War.[2] He served as a member of the Confederation of Health Service Employees (COHSE) union National Executive Committee and COHSE's Medical Guild from 1946 to 1951. Morgan died in 1956, aged 70.
