David Fabricius

Born 9 Mar 1564; died 7 May 1617 at age 53. A German astronomer, friend of Tycho Brahe and Kepler, and one of the first to follow Galileo in telescope observation of the skies. He is best known for a naked-eye observation of a star in Aug 1596, subsequently named Omicron Ceti, the first variable star to be discovered, and now known as Mira. Its existence with variable brightness contradicted the Aristotelian dogma that the heavens were both perfect and constant. With his son, Johannes Fabricius, he observed the sun and noted sunspots. For further observations they invented the use of a camera obscura and recorded sun-spot motion indicating the rotation of the Sun. David Fabricius, a Protestant minister, was killed by a parishioner angered upon being accused by him as a thief.
