Taught at Leyden in 1593; author of the first book on Austrian botany. His works on Austrian and Hungarian flora were considered standard works for more than 100 years. He introduced the horse chestnut (1576), the tulip and the potato (1588) to Vienna and made the town a centre of floriculture. His botanical studies in the Austrian Alps (esp. around the Oetscher and Schneeberg mountains) made C. the first researcher of alpine flora.
