[1] Jan Wils' daughter married Berchem, and when she heard nothing from his studio upstairs, she would bang on the ceiling with a mop to wake him up, assuming he had fallen asleep at his easel.
[1] According to the RKD he was baptized on June 15, 1603 in the Nieuwe Kerk and was buried there 22 October 1666.
