Cornelis de Houtman, Dutch explorer (d. 1599)
Cornelis de Houtman (2 April 1565 – 1 September 1599) was a Dutch merchant seaman who commanded the first Dutch expedition to the East Indies. Although the voyage was difficult and yielded only a modest profit, Houtman showed that the Portuguese monopoly on the spice trade was vulnerable. A flurry of Dutch trading voyages followed, eventually leading to the displacement of the Portuguese and the establishment of a Dutch monopoly on spice trading in the East Indies.
