David Ivon Jones
David Ivon Jones (18 October 1883 – 13 April 1924) was a South Africa-based Welsh communist, newspaper editor, and political prisoner — most famous as a leading opponent of South African racial segregation, and for being one of the first white activists in South Africa to fight for equal rights for black South Africans. Jones was also one of the founders of the Communist Party of South Africa, and in 1917 played a leading role in the formation of South Africa's first all-black trade union: the Industrial Workers of Africa (IWA).
