He was born on 20 December 1858, in Cork, Ireland, the son of Reverend John Watkins Benn. He received his formal education at Clifton College,^[1] then at Inner Temple.

He became a managing director, then the British Vice-Consul to Mobile, Alabama.

Benn became active in the Conservative Party, and stood in Battersea at the 1906 general election. In 1907, he was elected to London County Council, representing the equivalent seat, a post he held for four years. He stood for Parliament in Battersea again in January 1910. In December, he was instead elected at Plymouth.

In 1915 during the First World War he was a member of the House of Commons' 'Ammunition Committee', established by David Lloyd George as Minister of Munitions.^[2]

In 1926 he was created a baronet, of Plymouth in the County of Devon.^[4] From 1927, he was the Director of the International Chamber of Commerce.

Benn lost his seat in 1929, and at the next general election in 1931 was elected for Sheffield Park, but then lost this seat in 1935. In 1936 he was raised to the peerage as Baron Glenravel, of Kensington in the County of London.^[5]

He died on 13 June 1937 at the age of 78, without issue, when the baronetcy and barony became extinct. His body was buried at Hanwell Cemetery in Ealing, London.

He married Alys Maria Luling, daughter of Florenz Augustus Luling of New Orleans and later of Mobile, Alabama, on 9 May 1888.^[6][7]
