Conrad Dasypodius

Conrad Dasypodius, born in Frauenfeld in Thurgau in 1532 and dead in 1600, was a Swiss astronomer, mathematician and writer who became professor of mathematics in Strasbourg. The son of the humanist and lexicographer Petrus Dasypodius, he edited parts of Euclid's Elements in 1564, publishing a new edition because his school no longer had copies of the book that every student promoted to public lectures had to learn. In 1568 he published a work on the heliocentric theory of Copernicus, though it is unclear whether he was himself a heliocentrist. He designed the astronomical clock of Strasbourg Cathedral, built in 1572 to 1574, and translated writings of Hero of Alexandria from Greek into Latin.
