Cornelis Drebbel (ca. 1572-1633) from Alcmaar in the Netherlands was an engraver, engineer, alchemist and showman - and probably also one among the first European chain-smokers. He built and sold furnaces, microscopes and fountains, published a treatise 'On the nature of the elements', invented a submarine and discovered a dyeing process which made the fortunes of his heirs.
