Stephen Vaughan (1502-1549) was an English merchant, royal agent and diplomat, and supporter of the Protestant Reformation. Life Vaughan was a merchant of London. About 1520 he made the acquaintance of Thomas Cromwell, and in March 1523-4 he was in Cromwell's service. Through Cromwell's influence he was employed by Cardinal Wolsey on the business of Cardinal College. He was still mainly occupied with commerce, and was a member of the Company of Merchant Adventurers of London. He frequently visited Antwerp, and was entrusted with commissions on behalf of Cromwell and of Henry VIII, and about 1530 became royal agent or king's factor in the Netherlands. His principal duty was to negotiate loans with the Fuggers, on commission. John Hutton, governor of the Merchant Adventurers' Company, in 1529 instigated charges of heresy against Vaughan before William Warham, the Archbishop of Canterbury and Sir Thomas More. The influence of Cromwell protected Vaughan, but More continued to seek evidence against him, and succeeded in turning George Constantine to use, and the matter was raised again in 1532. Meanwhile, in 1531 Henry VIII asked Vaughan to persuade William Tyndale to retract his heretical opinions and return to England. Vaughan had various ineffectual interviews with Tyndale, and forwarded early copies of his books to the king. His efforts did not satisfy Henry VIII, who thought Vaughan too sympathetic towards Tyndale, though Cromwell said otherwise. Vaughan also interceded in Hugh Latimer's favour when he was cited before convocation in January 1532, and reacted by writing a protest against Henry's persecution of reformers. He weathered this storm over his Protestant views. On Hutton's death about 1534 Vaughan succeeded him as governor of the Merchant Adventurers' Company. He also became, in succession to Sir John Hackett, president of the factory of English merchants at Antwerp, residing in what was called 'the English House. On 10 April 1534 he was appointed a clerk in chancery, an office which did not prevent his residence at Antwerp, and was on 6 August 1534 appointed to a salaried royal secretarial position. In December 1532 Vaughan was sent on a mission to Paris and Lyons, and in August following accompanied Christopher Mont on his tour through Germany to report on the political situation; after visiting Nuremberg, Cologne, and Saxony, he returned to Antwerp in December, where he sought to effect the capture of William Peto. In January 1536 he was in England, and
