Witness at the wedding of his pupil Meindert Hobbema
In 1668 Ruisdael witnesses the marriage of Meindert Hobbema, his only registered pupil. He himself never married — according to Houbraken, to reserve time to serve his old father.
1672
Still comfortable after the Disaster Year
There is no record of Ruisdael owning land or shares, yet he appears to have lived comfortably even after the downturn of the disaster year 1672: in inventories of 1650–1679 his paintings averaged 40 guilders against 19 for attributed paintings generally. The legend that he died poor in a Haarlem almshouse confuses him with his cousin Jacob Salomonszoon.
15 October 1676

Art historians consider it most likely a case of mistaken identity (Pieter Scheltema suggested the artist's cousin), but the evidence is inconclusive.
