David Field Beatty, 2nd Earl Beatty, (22 February 1905 – 10 June 1972), styled Viscount Borodale from 1919 to 1936, was a Royal Navy officer and British Conservative Party politician.
Beatty was born on 22 February 1905. He was the eldest son of Admiral of the Fleet David Beatty, 1st Earl Beatty and his wife Ethel. He had one brother, Peter Beatty. From his mother's first marriage to Arthur Tree (a son of Lambert Tree), he had an elder half-brother, Ronald Tree, who served as MP for Harborough and friend of Winston Churchill. Ronald was married to Nancy Keene Field (née Perkins) (widow of his first cousin Henry Field) and Marietta FitzGerald (née Peabody), a granddaughter of the Rev. Endicott Peabody.[1]
His maternal grandfather was the American businessman Marshall Field. His father was the second son of five children born to Captain David Longfield Beatty and Katherine Edith Beatty (née Sadleir), both from Ireland: David Longfield had been an officer in the Fourth Hussars where he formed a relationship with Katrine, the wife of another officer.[2]
Beatty was educated at the Royal Naval College, Osborne, on the Isle of Wight, and the Royal Naval College, Dartmouth. In 1919, he gained the courtesy title of Viscount Borodale when his father was created Earl Beatty.
In 1919, he gained the rank of midshipman in the service of the Royal Navy. He was promoted to the rank of lieutenant in 1928. He would later serve in the Leicestershire Yeomanry, part of the Territorial Army, and gained the rank of lieutenant in 1933.
Beatty, holding the rank of lieutenant commander, was awarded the Distinguished Service Cross in 1942.
From 1931 to 1936 he was the Member of Parliament (MP) for Peckham. His half-brother Ronald Tree also sat in Parliament at this time, as member for Market Harborough, Leicestershire. During his time in parliament he held the office of Parliamentary Private Secretary to the Parliamentary Secretary to the Admiralty from 1931 until 1936. He moved to the House of Lords when he succeeded as 2nd Earl Beatty on his father's death on 11 March 1936.
He also served as a member of the London County Council in 1937. In 1945, he served as Under-Secretary of State for Air in the Caretaker Government after the Second World War.
Beatty married four times, the first three times to Americans:
Lord Beatty died on 10 June 1972 and was succeeded by his eldest son David Beatty, 3rd Earl Beatty. After his death his widow remarried in 1973 to Sir John Nutting, 4th Baronet of Chicheley Hall.[4]
