Extract, [1837-38] 73-240pp. no binding, Schaab wrote: ‘De geschiedenis der uitvinding van de boekdrukkunst, door Johann Gensfleisch, genaamd Gutenberg te Mentz’. Reaction to the treatise by Schaab on the invention of printing. Treatise on the invention of printing mentioning Laurens Janszoon Coster, Coster also spelled Koster, (born c. 1370, Netherlands-died 1440?, Haarlem?), Dutch rival of Johannes Gutenberg as the alleged inventor of printing.Little is known of this early printer, whose last name means ‘sacristan,’ his title as an official of the Great Church of Haarlem. He is mentioned several times in records between 1417 and 1434 as alderman, tax assessor, and treasurer and is presumed to have died in a plague that struck Haarlem in 1440, when his wife is recorded as a widow.
