Scheiner, Julius

 

Born Nov. 25, 1858, in Cologne; died Dec. 20,1913, in Potsdam. German astronomer.

In 1888, Scheiner and H. Vogel determined the radial velocities of stars by photographing stellar spectra. This enabled them to determine the orbit of the eclipsing variable star Algol and to explain the cause of the variations in its brightness.
