Overview
John Conduitt (; c. 8 March 1688 – 23 May 1737), of Cranbury Park, Hampshire, was a British landowner and Whig politician. He sat in the House of Commons from 1721 to 1737. He was married to the half-niece of Sir Isaac Newton, whom Conduitt succeeded as Master of the Mint.
Early life
The son of Leonard and Sarah Conduitt, John was baptised at St Paul's, Covent Garden, London, on 8 March 1688. In June 1701 he was admitted to St Peter's College, Westminster School, as a King's scholar. In 1705, while at Westminster, he was elected a Queen's scholar to Trinity College, Cambridge, with three others. He was admitted there in June of that year and matriculated to the University, but did not graduate, staying only two years.
Career
By 1707, based on his own account, he was "travelling" in Holland and Germany. In September 1710, he became judge advocate with the British forces in Portugal. He was a "very pretty gentleman" according to James Brydges. From October 1710, he acted as the Earl of Portmore's secretary when the latter arrived in Portugal (N&Q). During this time, he kept the Earl of Dartmouth informed about the Portuguese court. He returned to London by October 1711 with Lord Portmore. During the following year, he was made a captain in a regiment of the dragoons serving in Portugal, but by September 1713 he had been appointed Deputy Paymaster General to the British forces in Gibraltar. Those posts appear to have been remunerative, and in May 1717 he returned home to England a rich man. In 1720, Conduitt acquired the estate and house at Cranbury Park, near Winchester.
Parliament and Mint
In June 1721, Conduitt was elected, on petition, as a Member of Parliament for Whitchurch, Hampshire, which he represented during the 1720s as a loyal supporter of Robert Walpole's Whig government. Conduitt took an active interest in the running of Isaac Newton's office of Master of the Mint in the latter years of Newton's life, and after Newton's death in March 1727 Conduitt succeeded him to the post.
