David A. Thornley
David Thornley (31 July 1935 – 18 June 1978) was an Irish Labour Party politician and university professor at Trinity College, Dublin.
In December 1972 he called for the immediate release of Seán Mac Stíofáin, then leader of the Provisional IRA. He was re-elected at the 1973 general election. In 1976 he voted for the Criminal Justice (Jurisdiction) Bill despite misgivings. He told The Irish Times:
"When I get very depressed I drink too much. When I voted for the Criminal Justice (Jurisdiction Bill) I went on the batter for a forthnight [sic]."He lost his seat at the 1977 general election. In 1978, he joined the newly formed Socialist Labour Party stating that he had done so because: "There is no man in politics that I respect more than Noël Browne, despite our occasional differences. If the SLP is good for him, it's good enough for me".
Thornley died later that year (1978) in County Dublin, aged 42, from undisclosed causes.
The Trinity College Labour Branch is also known as the David Thornley Branch.
