Nicolaas Heinsius the Younger

Nicolaas Heinsius the Younger (1656, in The Hague – buried 12 January 1718, in Culemborg) was a Dutch physician and writer.

With little help of his father, he became a medical doctor at the age of 20, but had to flee the country in 1677 after he and several drunk friends had committed manslaughter in the streets of The Hague.

In 1695 he returned to the Netherlands, settling in Culemborg, at the time a free city and exempt from the Dutch ban imposed on him.

That same year he published Den vermakelyken avanturier, ofte De Wispelturige, en niet min Wonderlyke Levens-Loop van Mirandor (The Jolly Adventurer or the Unpredictable and not less Wonderful Life of Mirandor) (1695).

He further wrote five works on medicine, which were published in Cleves, and one other novel, Don Clarazel de Contarnos (1697).
