This building where Hotel IX is located was once the home and workshop of Herman Doomer, a furniture maker, ivory carver and frame maker from Germany. One of Herman Doomer’s clients was Rembrandt van Rijn. Rembrandt was a loyal customer who paid many visits to the workshop at Hartenstraat 8.
Along with his wife Baertje Martens he raised nine children, including the Golden Age landscape painter Lambert Doomer. After learning the skill of furniture making from his father, Lambert became a student of Rembrandt in 1640 and worked alongside the master in his studio. In that way he might have worked in one way or another on Rembrandt’s famous Night Watch.
Around 1640 Herman Doomer ordered two portraits, of his wife and himself, to be painted by Rembrandt. These are now located at the Metropolitan Museum of Art in New York and at the Hermitage in St. Petersburg. Several works of Doomer himself are in the permanent collection of the Rijksmuseum in Amsterdam.
