Denis Rooke

Sir Denis Eric Rooke (2 April 1924 – 2 September 2008) was an English industrialist and engineer.

Early life
Denis Eric Rooke was born in New Cross, London, the younger son of Frederick George Rooke, a printer and travelling salesman, and his wife Ada Emily née Brown. He attended Westminster City School and Addey and Stanhope School before studying mechanical engineering at University College London, taking a first-class degree in 1944. He then served in REME in Britain and India until 1949, attaining the rank of major.

He studied for a postgraduate diploma in chemical engineering at University College which he was awarded in 1949. He married Elizabeth Brenda Evans (1922-2017?) on 22 January 1949 in Deptford, London.She was an investigator providing research services, and they had a daughter, Diana.

Career
From 1949, he worked in the gas industry, first on coal tar by-products at the South Metropolitan Gas works where he was appointed deputy manager of the tar works in 1954. He was seconded to North Thames Gas in 1957 to work on reforming processes for producing town gas from natural gas and oil. He also worked on liquefied natural gas (LNG), pioneering the sea transport of LNG. He was aboard the ship, the Methane Pioneer, making the first delivery to Canvey Island of LNG to the UK in 1959.

Rooke joined the board of the Gas Council in 1966 as the member for production and supplies, with responsibility for developing gas fields. His greatest achievement was to help to bring natural gas from the North Sea to domestic, commercial and industrial premises across Britain. This entailed the conversion of all gas appliance and the construction of a network of high pressure pipelines. He claimed this was "perhaps the biggest peacetime operation in the nation's history".

He became deputy chairman of the Gas Council in 1972 and, along with the chairman, Sir Henry Jones, and Sir Arthur Hetherington, he was responsible for combining the Gas Council and 12 separate gas boards into the British Gas Corporation in 1973.

Rooke was appointed chairman of the British Gas Corporation in 1976. He was involved in several controversies. The Gas Council had formed a consortium to search for, and produce, offshore gas. At the same time, it was responsible for buying gas produced by other companies. The companies insisted on a market value approach to prices whereas the Gas Council purchased, more cheaply, gas priced on cost. The incoming Conservative government in 1979 wished to reform the nationalised industries. The government insisted that British Gas divest itself of oil exploration and production interests.

This was achieved through the establishment of Enterprise Oil. In 1986, British Gas was floated on the stock market; Rooke had insisted that British Gas should be privatised as an integrated entity. However, it was soon divided into three parts: Centrica, BG Group and Lattice. Rooke remained chairman until he retired in 1989.
