[1][2] He was a student of Cornelius van Poelenburgh, and though he was quite successful in imitating his master's style of landscape painting, he switched to portraits since he could make a comfortable living making flattering ladies portraits that made their skin look whiter.

[1] According to Houbraken, Haensbergen became an art dealer in The Hague with a man named "De Jode", who was "Drost van 't Haagse Hof".

[2] He may have meant the Baljuw Adriaan Rosa, a wealthy magistrate from The Hague whose brother Johan was consulted in valuing paintings for estate inventories.

Houbraken mentioned this same "De Jode" in his biographical sketch of the landscape painter Jan Both, a collaborator with Poelenburgh who Haensbergen probably knew personally.

Houbraken remarked on the beauty of a large painting 6 feet high of Argus Panoptes and Mercury that he had once seen himself in De Jode's collection.
