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.
[2] He was one of the nineteen children,[3] and the youngest of the five surviving sons of Sir William Lok (1480–1550),[1] 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.
After two years, however, the appointment was summarily cancelled, by the intrigues—as Lok asserted—of one Dorrington, in the employment of Sir John Spenser, alderman of London.
On 29 June 1608 Lok wrote to Robert Cecil, 1st Earl of Salisbury sending him intelligence of the warlike preparations of the king of Spain.
An essay, An conveniens sit Matrimonium inter Puellam et Senem from 1583, might imply that he was meditating a third marriage in his old age.
