Joseph Rheden
Joseph Rheden (born April 5, 1873 in Amlach , East Tyrol, † August 6, 1946 in Lienz ) was an Austrian astronomer .
Live and act
The son-in-law of the astronomer Johann Palisa studied astronomy, mathematics and physics at the University of Vienna from 1897 to 1901. From 1901 Rheden was an assistant at the Vienna University Observatory , and in 1906 he became an adjunct. In 1935 Rheden retired as a councilor . But he stayed as a volunteer at the observatory.
Mainly Rheden dealt with astrophotography and planet and comet observation. He also devoted himself to the astronomical time service. He equipped the observatory with a self-made receiver with which the institute's clocks were one of the first to be able to synchronize their own time displays with those of the international radio clock using radio time signals.
As early as 1898 he developed an instrument with which the meteor orbits could be recorded. From 1908 the photo laboratory with a normal astrograph was set up in the observatory according to Rheden's instructions. This astrograph made a large number of recordings, mostly of asteroids, to supplement the visual recordings of Palisa.
