Hermann Wilhelm Vogel (March 26 1834 – December 17, 1898) was a German photochemist and photographer who made key contributions to practical color photography. From 1860 he was a professor at Berlin's Technische Hochschule (from 1879, the Technical University of Berlin), where he introduced photography as a field of study.

In 1873 he discovered how to extend the spectral sensitivity of photographic emulsions, (which until then were then only sensitive to blue and UV light) to green light by adding dyes. By 1884 he had discovered how to extend the sensitivity into the orange. However the achievement of a fully panchromatic response, into the red, had to wait until fresh dye-discoveries, in the early 1900s, shortly after his death.

In addition to his work as a photographic technical innovator, Vogel taught Alfred Stieglitz between 1882 and 1886. He participated in at least two photographic expeditions to Egypt as well as others to Italy and possibly Asia.

After finishing school in Frankfurt (Oder) he studied at the University of Berlin earning his phd with Karl Friedrich August Rammelsberg 1863. The thesis, which was published in Poggendorffs Annalen ( [http://gallica.bnf.fr/ark:/12148/bpt6k152049/f509.table 119, pp497] ), had the title: Über das Verhalten von Chlorsilber, Bromsilber und Jodsilber im Licht und die Theorie der Photographie (Reactions of Silverchloride Silverbromide and Silveriodide with light and the theory of photography). This marked the beginning of his research of the photo process.
