Otto Hahn, Fritz Strassmann and Lise Meitner in 1939; I consider that the expression father of the atomic bomb is not adequate.
Martin Heinrich Klaproth, a German apothecary, considered in 1789 that a mineral from Joachmow is a new metal. In fact it was only an oxide.In 1842 Eugene Melchior Peligot, French chemist, separated uranium as a pure metal.
In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties. His rule states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic.
The name of the SI unit Hertz is derived from the name of German physicist Heinrich Rudolf Hertz.
Heinrich Rudolf Hertz was a very known German physicist
it is silver white. it is discovered by a German chemist. it was discovered in 1989.
Robert Julius Oppenheimer is credited with being the Father of the Atom bomb, but he was American.

Martin Heinrich Klaproth, a German chemist, discovered uranium (as an oxide) in 1789, in minerals from Johanngeorgenstadt (Germany) and Jachimov (Czech Republic).
Martin Heinrich Klaproth, a German chemist, discovered uranium (as an oxide) in 1789, in minerals from Johanngeorgenstadt (Germany) and Jachimov (Czech Republic).
Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (a mix of uranium oxides) in 1789. Klaproth confused the oxide with the metal. In 1841 the French chemist Peligot isolated uranium as a pure metal element. Henry Becquerel (also a Frenchman) discovered the natural radioactivity of uranium in 1896.
Uranium has discovered as an oxide by the German chemist Martin Heinrich Klaproth in 1789 studying a mineral from Joachimov (now in Cech Republic). As a pure metal uranium was prepared by Peligot in 1841.
Uranium was discovered as an oxide in 1789 by the German chemist Martin Heinrich Klaproth in a mineral (probable pitchblende) from Joachimov (now in Czech Republic); the pure metal was obtained in 1841 by Eugene Peligot in France.
The first isotope of protactinium (234mPa) was discovered by Kasimir Fajans and Otto Gohring in 1913 (Germany). The isotope 231Pa of protactinium was discovered by Austrian/Jewish physicist Lise Meitner and by Otto Hahn, a German physical chemist in 1918 and simultaneously by Frederick Soddy and John Cranston (England). Protactinium exist in extremely low concentrations in uranium ores (approx. 3 mg/kg).

This is the German-born physicist Albert Einstein, Nobel Prize laureate.

In 1789 Martin Heinrich Klaproth, a German chemist, analyzed a new mineral and has confused this mineral (an oxide) with a new metal. The name uranium was proposed also by Klaproth, derived from the name of the planet Uranus discovered by Herschel in 1781. In 1841 a French scientist, Eugene Péligot isolated the pure metallic element uranium.
