Laurens Janszoon Coster (1370-1440), or Laurens Jansz Koster, purported inventor of a printing press from Haarlem. He discovered printing simultaneously with Johannes Gutenberg and is regarded in the Netherlands as having invented it first. Sometime in the 1420s, Coster was carving letters from bark for the amusement of his grandchildren, and observed that the letters left impressions on the sand. He proceeded to invent a new type of ink that didn't run, and began a printing company based on his invention with a primitive typesetting arrangement using moveable type. Using wooden letters at first, he later used lead and tin. He is said to have printed several books with several assistants including the letter cutter Johann Fus (Faust) who, when Laurens was nearing death, broke his promise of secrecy and stole his presses and type and took them to Mainz where he started his own printing company.
