Description

An undated photographic negative of the spectra of aluminium and hydrogen mounted on a glas microscope slide. Taken by Victor Schumann (1841-1913), the German physicist, they are early examples of photographic spectra made in ultra-violet, at wavelengths beyond the blue end of the visible spectrum. In this instance, Schumann presented the mounted spectra to Sir William Huggins and Lady Huggins, important pioneers in the new discipline of astrophysics that emerged during the latter stages of the 19th century.
