Michael Lok (or Locke; c. 1532 – c. 1621) was an English merchant and traveller, and the principal backer of Sir Martin Frobisher's voyages in search of the Northwest Passage. Family Michael Lok was born in Cheapside in London, by his own account in 1532. He was one of the nineteen children, and the youngest of the five surviving sons of Sir William Lok (1480–1550), gentleman usher to Henry VIII and mercer, sheriff and alderman of London, by his second wife, Katherine Cooke (d.1537), daughter of Sir Thomas Cooke of Wiltshire. One of his sisters was the Protestant exile, Rose Lok (1526–1613). His father, Sir William Lok, was the great-great-great-grandfather of the philosopher John Locke (1632–1704). Career He was kept at school until 1545, when he was thirteen, at which time he was sent by his father to Flanders and France 'to learn those languages and to know the world' He spent seven years in Flanders 'following the trade of merchandise', which Williamson suggests was his term of apprenticeship to the Company of Merchant Adventurers. In 1552 he went to Spain, following his business as a merchant, and there and at Lisbon saw the trade of the Spanish West Indies, and the East Indies. During 24 years he travelled, and was captain of a ship of one thousand tons trading in the Levant. In the course of his voyages he met Martin Frobisher, and in 1576 entered into a scheme for a voyage in search of the Northwest Passage, supplying many of the necessaries at his own cost. When the Cathay Company was formed in March 1577, Lok was appointed governor for six years. The venture, however, entirely failed, and in January 1579 he had to petition the Privy Council for relief and assistance. In June 1581 he was again petitioning the Privy Council, from the Fleet Prison, condemned at the suit of William Borough to pay for a ship bought for Frobisher's last voyage, though he claimed the debt was not his; he was also bound for a larger debt of the Cathay Company. In 1614–15 he was still being sued for a debt for stores supplied to Frobisher's ships. In 1587–8 Lok was in Dublin, and in 1592 went out to Aleppo as consul for the Levant Company for four years. After two years, however, the appointment was summarily cancelled, by the intrigues—as Lok asserted—of one Dorrington, in
