He is thought to have first started as a cabin boy, then worked his way up to a ship captain.
His first voyage was to find a northern route to find the Pacific Coast of Asia.
In 1609, he sailed for the Dutch East India Company.
On his last voyage, he wanted to further explore the Hudson Bay. However, he and his crew had to stay there for the winter, causing them to mistrust him. They left his and crew members still loyal to Hudson on a boat, and no one knows what happened to them.
Today, he is credited for his explorations of Canada and the US. There are many bodies of water named after him, such as the Hudson River.
