Victor Schumann (21 December 1841 – 1 September 1913) was a
spectroscopist who in 1893 discovered the vacuum ultraviolet
.
Schumann wished to study the "
allowing himself to be the first to measure spectra below 200 nm. Oxygen gas would absorb the radiation with a wavelength below 195 nm, but Schumann placed the entire apparatus under vacuum. He prepared his own photographic plates with a reduced layer of gelatin.He published on the
vacuum tubes.[2]
His work opened the way to atomic emission spectroscopy, leading eventually to the discovery of the hydrogen spectral lines series (Lyman series) by Theodore Lyman in 1914.[1]
