J. Bartsch

Jacob Bartsch (* 1600 in Lauban ; † December 26, 1632 there ) was a German astronomer .

Bartsch wrote several astronomical writings, including Planisphaerium Stellatum . He was the son-in-law of Johannes Kepler and partially supported him with his calculations. After his death he edited the utopian work Kepler's Somnium ("The Dream").

He studied astronomy and medicine at the University of Strasbourg .

In 1624 Bartsch published star maps under the title Usus astronomicus planisphaerii stellati. Bartsch took over the following constellations described by Petrus Plancius in 1613 , which were depicted on celestial globes by Pieter van den Keere , and made them known to a wider audience: giraffe , southern cross , unicorn , net .

Bartsch married Johannes Kepler's daughter Susanna on March 12, 1630 and had already helped him as an assistant in his scientific work. After Kepler's death in 1630, Bartsch raised money for Kepler's widow and tried to posthumously publish Kepler's book Somnium ; however, he previously died of the plague. The work was published in 1634 by Kepler's son Ludwig (1607–1663).
