KOSTER'(or [[Coster), Laurens]] (c. 1370-1440) Dutch printer,, whose claims to be considered at least one of the inventors of the art (see Typography) have been recognized by many investigators.
His real name was Laurens Janssoen-Koster (i.e.
Koster (Haarlem, 1834); Van der Linde, De Haarlemsche Costerlegende (Hague, 1870).
In the great market place in the centre of the city are gathered together the larger number of the most interesting buildings, including the quaint old Fleshers' Hall, built by Lieven de Key in 1603, and now containing the archives; the town hall; the old Stadsdoelen, where the burgesses met in arms; the Groote Kerk, or Great Church; and the statue erected in 1856 to Laurenz Janszoon Koster, the printer.
It was in the days of Duke Philip that Lorenz Koster of Haarlem contributed his share to the discovery of printing.
