1835–1897
A 19th-century German astronomer remembered for his sharp eye at the telescope, he discovered comets, studied nebulae, and gave his name to the famous double star cluster h Persei and Chi Persei pairing often called Winnecke 4. His career took him from major observatories in Germany and Russia to a professorship in Strasbourg before illness cut his work short.

by Friedrich August Theodor Winnecke
Born on February 5, 1835, near Hannover, Friedrich August Theodor Winnecke studied astronomy in Göttingen, Berlin, and Bonn, working with some of the leading astronomers of his day. He built his reputation as a careful observer and spent key years at Pulkovo Observatory near Saint Petersburg, one of the great research centers of 19th-century astronomy.
Winnecke is best known for discovering several comets and for his observations of nebulae, star clusters, and double stars. His name remains attached to objects such as Comet 7P/Pons-Winnecke and the visual double cluster sometimes called Winnecke 4, reflecting the kind of practical, sky-mapping astronomy that defined his career.
After returning to Germany, he became professor of astronomy in Strasbourg from 1872 to 1881. Later in life his health declined, and he died in Bonn on December 3, 1897, but his work left a lasting mark on observational astronomy.
