Life
Vogel went to school until 1845 in Dobrilugk, where he subsequently 1848-51 intermittently completed a commercial apprenticeship. After that, he studied chemistry and physics at the Commercial Academy in Berlin and was assistant to Karl Friedrich Rammelsberg and Heinrich Wilhelm Dove, and since 1860 assistant at the mineralogical museum since 1858. In 1863 he founded " along with some friends the > Photographic club in Berlin < ", from the 1869 until the end of the 19th century led by him association for the promotion of photography emerged; also he published since 1864, the Photographic messages ( Berlin).

With the photo chemist and inventor Johann Baptist Obernetter bird worked on orthochromatic processes that provide images of colored objects in proper tone.

In his honor, received on 26 August 1965 in a neighborhood where the streets after pioneers of photo technology were named the bird line in Spandau district Staaken her name.

Work, meaning and students
Bird studies span all areas of photography. Of particular note are:
- To the studies of the sensitizers, which led him in 1873 to the discovery can pick up objects in the correct tonal values .
- His work on alkaline Development ( collodion, silver bath, pigment printing )
- Photographic studies of perspective and of the principles of lighting and studio construction ( 1869)
- The experiments on the performance of lenses and
- Be photometer.
From 1873 he worked with special Spektralfotografie and spectral analysis, also he constructed in 1877 Universalspektroskop. Bird was considered a staunch advocate named after Jacob Wothly " Wothlytypie ".
Among the best known and most distinguished pupils bird photography Alfred Stieglitz heard. .
