Willem Janszoon

[3] Around 1600 he became the father of Jan Willemsz before setting sail again on 5 May 1601, for the East Indies as master of Lam, one of three ships in the fleet of Joris van Spilbergen.

[4] Janszoon sailed from the Netherlands for the East Indies for the third time on 18 December 1603, as captain of Duyfken (or Duijfken, meaning 'Little Dove'), one of twelve ships of the great fleet of Steven van der Hagen.

Finding the land swampy and the people inhospitable (ten of his men were killed on various shore expeditions), Janszoon decided to return at a place he named Kaap Keerweer (lit.

'Cape Return', the name persist as Cape Keer Weer), south of Albatross Bay, and arrived back at Bantam in June 1606.

[7] In 1611, Janszoon returned to the Netherlands, believing that the south coast of New Guinea was joined to the land along which he had sailed, and Dutch maps reproduced that error for many years.

[9] This is generally interpreted as a description of the peninsula from Point Cloates (22°43′S 113°40′E / 22.717°S 113.667°E / -22.717; 113.667) to North West Cape (21°47′S 114°09′E / 21.783°S 114.150°E / -21.783; 114.150) on the Western Australian coast, which Janszoon presumed was an island without fully circumnavigating it.

[11] Janszoon was awarded a gold chain worth 1,000 guilders in 1619 for his part in capturing four ships of the British East India Company near Tiku on West Sumatra, which had aided the Javanese in their defence of the town of Jakarta against the Dutch.

The information from his charts was included in the marble and copper maps of the hemispheres on the floor of The Citizens' Hall of the Royal Palace in Amsterdam.
