Jacob J. Hinlopen (1582 – 1629 in Amsterdam) lived in a house with Hinlopen in the gable, now at 155 Nieuwendijk. He traded in cloth and Indian wares. In 1602 he was co-founder of the Dutch East India Company in Enkhuizen, his descendants inherited very old stocks. He also was the first person of Flemish origin, that in 1617 obtained a seat in the City Council.
Jacob J. Hinlopen became a friend of Joost van den Vondel, at that time also an Arminian. His wife was Sara the Wael (1591–1652), the daughter of a Haarlem burgomaster, beerbrewer and investor in the new development, the Lastage. The couple inhabited Herengracht 130, a double wide mansion.
His brother Tijmen, to whom the Hinlopen Street on Svalbard has been named was the director of the Noordsche Company and traded on Russia. Her brother Jan the Wael, just like their father burgomaster of Haarlem, was locked up in 1650 some weeks in the castle Loevestein with Jacob de Witt, before the raid on Amsterdam by stadholder William II of Orange.
After the death of their mother the two sons inherited the mansion, designed by Philips Vingboons. Today Pijnenburg in the surroundings of Soest is still the largest domain in private possession. The ancestral house near the harbour was sold. The brothers bought lots in the Jordaan, hired a carpenter, and speculated with the building of cheap houses.
Jacob became commissioner of the Desolate Boedelkamer (Chamber of Insolvent Estates) and was involved in the selling of Rembrandt possessions and the inheritance of Titus van Rijn, the son of Rembrandt.
Just like its brother Jan also Jacob J. Hinlopen (1621–1679) is known as a collectioneur of paintings, among other paintings: a Samson and Christ and the adulterous woman, both by Rembrandt. That last work he had bought in 1657 for 1500 guilders on an auction from Joannes the Renialme, an art trader. That painting was then regarded higher than any other work by Rembrandt.
