Lambert Doomer (11 February 1624 – 2 July 1700) was a Dutch Golden Age landscape painter.

[1] Lambert was trained as a furniture maker like his father, but seemed to enjoy drawing more than woodworking and he became an artist.

Rembrandt painted portraits of his parents for their 25th wedding anniversary, which was unusual at the time, in 1638.

[2] To finish his education, Lambert traveled to France with Willem Schellinks who was three years younger than he was, in 1646.

He was able to buy at auction a large amount of Rembrandt drawings and sketchbooks after that artist's bankruptcy in 1657.
