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.

Here, as part of a full-page entry, I found everything I wanted to know: "From 1868 William Huggins in London and Angelo Secchi in Rome attempted to detect Doppler line shifts by the visual observation of stellar spectra, but it was not until Hermann Carl Vogel and Julius Scheiner in Potsdam photographed stellar spectra in 1888-1892 that reliable Doppler shifts, for some fifty stars, were first observed.
