Chubb was the last private owner of Stonehenge, which he donated to the British government in 1918. He attended Christ's College, Cambridge where he was awarded a double first in Science and Law, leaving with Master of Arts and Bachelor of Law degrees. He became a barrister and amassed a considerable fortune. Sir Cecil also served on Salisbury City Council, was a Justice of the Peace and became a successful racehorse owner and breeder of Shorthorn cattle. He gave Stonehenge to the nation on 26 October 1918. To mark his generosity, he was made a baronet in 1919 by Lloyd George.
