Description
An entry on Christopher Scheiner, a German Jesuit astronomer born near Mindelheim in July 1575, he died in Silesia in July 1650. He joined the Society of Jesus in 1595, studied mathematics at Ingolstadt, and taught at Dillingen, then at Ingolstadt, where he taught Hebrew and mathematics and took up research. He had invented the pantograph, a copying instrument, and now built a telescope to study the sun.
With a student helper, Scheiner projected the sun's image on a screen. In March 1611 he found sunspots, a sight so against the philosophy of the day that his superiors barred his name from print. His letters, issued by Welser at Augsburg in 1612 under a false name, described the spots' rotation and the bright faculae. Galileo claimed priority, and Fabricius had seen the spots earlier still, but Scheiner's continuous observations stand undisputed. His Rosa Ursina of 1626 to 1630 remains a standard treatise on the sun.
