Catherine Ellis Williamson (née Goodbody; 1 May 1896 – 25 April 1977) was an Irish politician.
Born in Dublin to lawyer Lewis Goodbody and his wife Edith (née Pim), Williamson studied at Cheltenham Ladies College and in St Germain-en-Laye in Paris. For part of World War I, she taught Braille at St Dunstan's in London, before becoming a director of J. J. Williamson & Sons, her family's tannery business in Canterbury.[1]
Williamson joined the Labour Party and was elected to Canterbury City Council in 1935, serving as Mayor of Canterbury from 1939 to 1941: the city's first woman mayor.[2] Soon afterwards, she defected to the Common Wealth Party, for which she stood in the 1943 Ashford by-election, taking 30.3% of the vote against a single opponent. She stood in Canterbury at the 1945 United Kingdom general election but, facing both Labour and Conservative opponents, could only take 2.6% of the votes cast.[3]
Williamson rejoined Labour late in the 1940s, and stood in East Grinstead at the 1950 general election, and in Hastings in 1951.[4] She travelled widely, particularly to China, where she met Mao Zedong and Zhou Enlai.
Long a member of the Society of Friends, Williamson also identified as a member of the Church of England, and joined the Chinese Patriotic Catholic Association.
