The isolation of methyl jasmonate from jasmine oil derived from Jasminum grandiflorum led to the discovery of the molecular structure of jasmonates and their name.

Analytical problems, such as the isolation of certain organic radicals, attracted his attention at first, but he soon turned to chemical syntheses, and he was only about twenty-five years of age when an investigation, doubtless suggested by the work of his master, Robert Bunsen and Hermann Kolbe, on cacodyl, yielded the interesting discovery of organometallic compounds.

The formal discovery of the element was made in 1895 by two Swedish chemists, Per Teodor Cleve and Nils Abraham Langlet, who found helium emanating from the uranium ore cleveite.

Chemical separation of the new formed elements from the uranium yielded material with low half-life, and, therefore, Fermi announced the discovery of a new element in 1934, though this was soon found to be mistaken.

The history of nuclear physics as a discipline distinct from atomic physics starts with the discovery of radioactivity by Henri Becquerel in 1896, while investigating phosphorescence in uranium salts.

The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus.

Before the discovery of radioactivity, uranium was primarily used in small amounts for yellow glass and pottery glazes, such as uranium glass and in Fiestaware.

The discovery of the radioactivity of uranium ushered in additional scientific and practical uses of the element.

In early 1896, in the wave of excitement following Wilhelm Conrad Röntgen's discovery of X-rays the previous fall, Becquerel thought that phosphorescent materials, such as some uranium salts, might emit penetrating X-ray-like radiation when illuminated by bright sunlight.

After the discovery of uranium in 1958 near Tordilla Hill, ten miles west of Falls City, uranium mining and milling developed.

The city was established as a planned community for the mining industry in 1955 after the discovery of uranium in the area, and named after the small lake on its northern edge.

She was launched in 1964 and named in honour of Otto Hahn, the German chemist and Nobel prizewinner, who was credited with the discovery of nuclear fission of uranium in 1938.
