The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the recently discovered planet Uranus. Eugène-Melchior Péligot was the first person to isolate the metal, and its radioactive properties were discovered in 1896 by Henri Becquerel.
Klaproth discovered uranium (1789) [6] and zirconium (1789). He was also involved in the discovery or co-discovery of titanium (1795), strontium (1793), cerium (1803), and chromium (1797) and confirmed the previous discoveries of tellurium (1798) and beryllium (1798). [7] [8] Klaproth was a member and director of the Berlin Academy of Sciences. [2]
Patricio "Paddy" Martinez (1881– August 26, 1969) [1] was an American prospector and shepherd who discovered uranium at Haystack Mesa in the San Juan Basin near Grants, New Mexico, in 1950. [2] This was the first discovery in the Grants Uranium District, and led to a uranium boom that lasted almost 30 years. The San Juan Basin yielded 60% of ...
In 1789, Martin Klaproth discovered uranium. He later experimented with the use of the element as a glass colourant. Uranium glass became popular in the mid-19th century, with its period of greatest popularity being from the 1880s to the 1920s.
The chemical element uranium, discovered in 1789 by the German chemist Martin Heinrich Klaproth, was named after the then-newly discovered Uranus. [172] Lydia Sigourney included her poem The Georgian Planet in her 1827 collection of poetry.

On February 24, Glenn T. Seaborg, Edwin McMillan, Emilio Segrè, Joseph W. Kennedy, and Arthur Wahl make the discovery of plutonium at the Berkeley Radiation Laboratory. They identify plutonium-238 from oxidation of a sample of beta-decaying neptunium-238, produced via deuteron bombardment of uranium in the 60-inch cyclotron. [26]
