Dafydd Arwyn Jenkins (christened David; 1 March 1911 – 5 May 2012) was a Welsh barrister, activist, and legal scholar and historian.
Born in London to Welsh parents, William and Elizabeth Jenkins, he was educated at Sidney Sussex College, Cambridge, and called to the bar at Gray's Inn in 1934.
[1][2] A "socialist Anglican, a man of letters, a Welsh-language publisher ... and a nationalist",[3] Jenkins practised as a barrister on the South Wales circuit.
Ten years later, he was appointed to the chair in legal history and Welsh law, serving until his retirement in 1978 after which he was an emeritus professor.
He translated and commented widely upon medieval Welsh legal texts and Welsh-language law books.
