Samuel Vyvyan Trerice Adams (22 April 1900 – 13 August 1951), known as Vyvyan Adams, was a British Conservative Party politician. He was the Member of Parliament (MP) for Leeds West from 1931[1] to 1945, when he was defeated by the swing to Labour. He stood unsuccessfully in the Fulham East constituency in 1950. He had been adopted for the safe Conservative seat of Darwen early in 1951, but died later that year.
His Times obituary was headed Intellectual Honesty and Independence. He was opposed to appeasement of Mussolini (in Abyssinia) and Hitler, and was one of the few Conservative MPs (with Leo Amery, Duff Cooper, Anthony Eden, Harold Nicolson and Winston Churchill) to oppose the Munich agreement with Hitler in 1938. He was opposed to the death penalty.
He was educated at King's College School, Cambridge, Haileybury, and King's College, Cambridge (MA). He married in 1925 Mary Campin, who was later a television producer and programme director. He was a barrister, and was a Major in the Duke of Cornwall's Light Infantry of the British Army in World War II.

He wrote several books, the first three under the pseudonym Watchman:
