⏹ as a cupola von Stradunitz Friedrich August
Kekulé von Stradonitz, Friedrich August

German chemist ( 1829 - 1896 )
Kekule began studying architecture in Giessen, then turned to the study of chemistry at the hands of the scientist (Dumas), so he worked as a professor of chemistry in Ghent and in Bonn. chemical equivalence.
Kekule managed to manufacture acetylene. He also discovered the quaternary valency of coal (carbon), and Kekuleh's concept of the ring structure of benzene remains a remarkable achievement in the field of organic chemistry. He states that he came up with the idea of ​​the ring after he saw in his dream a snake biting its tail.

⏹ Keeler, James Edward
James Edward Keeler,

American astronomer (1857 - 1900)
Keeler received his education at Johns Hopkins University, Heidelberg and Berlin, and finally worked as director of the Lick Observatory • Keeler used “Doppler displacement” in the spectral lines to prove that the rings surrounding Saturn are composed of small fragments, and Maxwell had previously proposed For this interpretation, Keller measured the wavelength of green light for the nebula spectrum, and discovered by imaging 120,000 nebulae and concluded that spiral nebulae are a dominant type. Keller wrote a book entitled: Spectroscopic Observations of Nebulae (1894).

⏹ Keller, Wolfgang Kohler Wolfgang

⏹ Kilker, Rudolf Albert von

⏹ Keilin, David Keilin,

English biologist (contemporary?)
Killen learned in Cambridge and worked there as a teacher of biology, and Killen was chosen as a Fellow of the Royal Society. · Killen discovered, while studying cells, the respiratory (iron-containing) cellular pigment (Cytochrome). Kellen conducted a series of distinguished research in biochemistry as well as on dipterous insects.
