Life
Leuschner was born in the USA, grew up in Germany and returned to the USA to study. In 1888 he received his degree from the University of Michigan . He then continued his studies at the Lick Observatory , but soon got into an argument with his militant teacher, Director Edward S. Holden , so that he left the observatory without a degree. Leuschner returned to Germany and enrolled at the Friedrich-Wilhelms-Universität Berlin , where he obtained his doctorate in 1897. His doctoral thesis, which outlined theses on the orbits of comets , received the highest praise.
He returned to California and became professor of astronomy at the University of California, Berkeley . Here he spent the next half century. He founded the Leuschner Observatory, which was later named after him. The Lick Observatory now also had a new director. Together with this, James E. Keeler , Leuschner developed programs that enabled students to complete their studies at both observatories.
Leuschner's main field of activity was calculating the orbits of comets and asteroids . As a teacher, he brought more than 60 students to doctoral degrees in this field.
In 1913 he became principal at the Graduate School of Berkeley. In the same year he was elected to the National Academy of Sciences . He was also a founding member of the Pacific Astronomical Association , served as President of the Association of American Professors for one term and chaired the Committee on Comets and Minor Planets of the International Astronomical Union for 20 years .
