Sure, here is summary about Abel Janszoon Tasman:

Abel Janszoon Tasman (Dutch: [ˈɑbəl ˈjɑnsoːn ˈtɑsmɑn]; 1603 – 10 October 1659) was a Dutch seafarer and explorer best known for his voyages of 1642 and 1644 in the service of the Dutch East India Company (VOC). He was appointed by the VOC to explore the uncharted regions of the Southern Pacific Ocean and discovered Van Diemen's Land, Staten Landt, and Nieuw Zeeland. Despite his achievements, his expedition was not entirely successful due to a violent confrontation with the Māori people on the South Island of New Zealand. Nonetheless, his expedition paved the way for further exploration and colonization of Australia and New Zealand by the Europeans. Abel Tasman was born around 1603 in Lutjegast, a small village in the province of Groningen, in the north of the Netherlands.

He served the Dutch East India Company until his death in 1659, leaving behind a legacy as one of the greatest explorers of his time. He was engaged to marry 21-year-old Jannetje Tjaers, of Palmstraat in the Jordaan district of the city, and took part in a voyage to Seram Island. He was second-in-command of a 1639 expedition of exploration into the north Pacific under Matthijs Quast, which reached Fort Zeelandia and Deshima.

The Council of the Indies dispatched Tasman and Franchoijs Jacobszoon Visscher on a voyage to explore the Provinces of Beach, which had appeared on European maps since the 15th century. Tasman attempted to land in North Bay, but the sea was too rough, so he turned away and continued his continent-hunting.
Tasman and his crew sighted land on the north-west coast of New Zealand, naming it Staten Landt in honour of the States General. Tasman's expedition encountered a group of Māori who attacked four sailors and named the area "Murderers' Bay".

Tasman's second voyage was a disappointment for the Dutch East India Company, who decided that a more persistent explorer should be chosen for future expeditions. Tasman's voyage in 1642-43 proved that the small fifth continent was not joined to any larger sixth continent, and his suggestion that New Zealand was the western side of that Southern Continent was seized upon by European cartographers.

Tasmanians have named places after him, including the Tasman Peninsula, Tasman Highway, Tasman Glacier, Tasman Lake, Mount Tasman, and Abel Tasman Monument.
