Robert Monsey Rolfe, 1st Baron Cranworth (18 December 1790- 26 July 1868), Lord Chancellor of Great Britain, elder son of the Rev. Edward Rolfe, was born at Cranworth, Norfolk. Educated at Bury St Edmunds, Winchester, and Trinity College, Cambridge, he was called to the bar at Lincoln's Inn in 1816, and attached himself to the chancery courts. He represented Penryn and Falmouth in parliament from 1832 till his promotion to the bench as Baron of the Exchequer in 1839. In 1850 he was appointed a Vice-Chancellor and created Baron Cranworth, and in 1852 he became Lord Chancellor in Aberdeen's ministry. He continued to hold the chancellorship in the administration of Palmerston until the latters resignation in 1858. He was not reappointed when Palmerston returned to office in 1859, but on the retirement of Lord Westbury in 1865 he accepted the great seal for a second time, and held it till the fall of the Russell administration in 1866. Cranworth died in London on 26 July 1868. Never a very zealous law reformer, Cranworth's name is associated in the statute book with only one small measure on conveyancing. But as a judge he will continue to hold first rank. His judgments were marked by sound common sense, while he himself was remarkably free from the prejudices of his profession. Few men of his day enjoyed greater personal popularity than Cranworth. He left no issue and the title became extinct on his death.
