German physicist who specialized in electric discharges in gases and plasma physics.

In 1918, he was called by Johannes Stark, Director of the Institute of Physics at the University of Greifswald, to be extraordinarius professor there. In 1921, Seeliger took the position of ordinarius professor for theoretical physics at the University. He became Director of the Institute of Physics in 1940.

In collaboration with Ernst Gehrcke at the PTR, Seeliger continued his research on electrical discharges in gases. In the spring of 1912, Gehrcke and Seeliger determined that light from cathode rays (electron beams) passing through gases, such as nitrogen and mercury vapor, became longer in wavelength, as the velocity of the cathode rays were slowed, i.e., becoming lower in energy. These results, through experiments in 1912 and 1913, were clarified and interpreted, by James Franck and Gustav Hertz, nephew of Heinrich Hertz; for their discovery of the laws governing the impact of an electron upon an atom, Franck and Hertz were awarded the Nobel Prize in 1925.

He died 20 January 1965.
