Coke, Thomas William (1752-1842), Earl of Leicester of Holkham, was one of the first British agriculturists to improve land and farm produce by the rotation of crops, and by the use of root crops to feed livestock. He helped improve the breeds of Devon cattle, Southdown sheep, and Suffolk pigs. He was the first to grow wheat instead of rye in western Norfolk, England. He was born on May 4, 1752, at Holkham, in Norfolk, and represented Norfolk in Parliament. He was made an earl in 1837. He died on June 30, 1842.
