Władysław Dziewulski

Władysław Dziewulski (1878 – February 6, 1962) was a Polish astronomer and mathematician.

He studied mathematics and astronomy in his native Warsaw. He then went to the University of Göttingen in Germany to complete his education. In 1903, he was named as an assistant at the astronomical observatory in Kraków that belonged to the Jagiellonian University. In 1906, he gained his Ph.D. In 1919, he became a professor of the Batory University in Vilna, then at the Nicolaus Copernicus University in Toruń. He spent the last part of his life in Vilnius.

He spent most his life performing astronomical research, and published over 200 papers. He focussed on the gravitational perturbations of minor planets, movements of stellar groupings, and photographic photometry.

Dziewulski crater on the Moon is named after him, as is the Wladyslaw Dziewulski Planetarium in Toruń.
