John Cam Hobhouse, 1st Baron Broughton, GCB, PC, FRS, known as Sir John Hobhouse, Bt, from 1831 to 1851, was an English politician and diarist.
He was the eldest son of Sir Benjamin Hobhouse, 1st Baronet, and Charlotte, daughter of Samuel Cam. He was educated at Westminster School, and at Trinity College, Cambridge where he graduated in 1808. Broughton took the Hulsean prize in 1808 for his Essay on the Origin and Intention of Sacrifices. At Cambridge he founded the "Whig Club," and the "Amicable Society".
While at Cambridge Broughton became good friends with Lord Byron, who accompanied him on a tour in Spain, Greece and Turkey in 1809. Hobhouse was present at the Battle of Dresden in August 1813, and, following the Coalition armies into France, he saw Louis XVIII enter Paris in May 1814.
