Spencer Bernau Wilks (26 May 1891 – 10 March 1971) was an English manager, administrator and designer in the motor manufacturing industry.

He served variously in positions including Managing Director, Chairman, and President of the Rover Company from 1929 until the 1960s.

[2][1] Wilks was initially trained as a solicitor, but his wife Kathleen Edith was a daughter of William Hillman, founder of the Hillman Motor Car Company, and so he became a joint manager in 1921 on the death of his father in law.

[1] In 1947, he founded Land Rover around Maurice's design for a small, sturdy, economical, four wheel drive utility vehicle modelled on the Willys Jeep.

He died on 10 March 1971, aged 79 in Glenegedale, a city of the Scottish Islay Island.
