Life

Kaspar Uttenhofer was born in Nuremberg in 1588, the seventh son of the second marriage of Georg Uttenhofer, a tailor. His father died on January 9, 1563, leaving the family in good economic conditions. One of his brothers was Anthoni Uttenhofer (1542-1609), an artist specialized in etching.[3]

His personal life is little known, according to the mathematician Daniel Schwenter,[4] Uttenhofer devoted most of his life to improving his knowledge being self-taught. He wrote various books, the most renowned is probably the Pes mechanicus in which the author explained how to easily build a sundial.

He wrote the Judicium de nupero Cometa astrologico-historicum after spotting comet (C/1618 W1) in the Boötes constellation.[5] He died in his home city of Nuremberg in 1621.
