museum is specialized in restoration and research on the works of Haarlem painters in the 17th century and of the painters of the 16th century who taught them to paint, most notably Jan van Scorel, Maerten van Heemskerck, Hendrick Goltzius and Cornelis van Haarlem. In the late 19th century the museum became something of a pilgrimage site for young impressionists, who were fascinated by the loose brushwork visible in the two group portraits of regents by Hals that he painted when he was in his eighties. This is the reason that after the move to the present location in 1913, the museum took on the name of Frans Hals as these were considered the most prominent paintings of the collection at the time. The museum is still famous for group portraits by Hals, but since the group portraits from the military guilds were cleaned in the early 20th century, it is these which most visitors come to see today. Most of the objects and paintings can not be displayed for lack of space, and the museum rotates its collection through exhibitions at various locations in Haarlem, though works by some prominent painters cannot be lent out and remain in storage. Installed art from other Haarlem locations Several stately rooms saved from torn-down Haarlem houses have been partially reconstructed and a collection of Haarlem silver saved from various local churches can be seen in the former regent rooms of the almshouse, which now seem much grander than they were originally. The windows have been decorated with art by anonymous Haarlem glass artists, most of which has been acquired through municipal demolitions work. Spread along the corridors are beautiful Dutch tiles from local salvage operations that have been installed along the walls, accompanied by 17th century furniture including clocks, chairs, and chests. The museum as an institution is only responsible for its collection, which is mostly oil paintings. Other applied art that has been installed is the responsibility of the municipal culture department, and the museum rents the premises from them. This is the reason that visitors are offered much more information about the paintings than about other aspects of the building, including the objects in the courtyard. List of painters Between 1605 and 1635 over 100,000 paintings were produced in Haarlem. Not all of these have survived, and most have left town, but this does say something about the artistic climate
