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 contained 60% ...
Finely divided uranium metal presents a fire hazard because uranium is pyrophoric; small grains will ignite spontaneously in air at room temperature. [12] Uranium metal is commonly handled with gloves as a sufficient precaution. [143] Uranium concentrate is handled and contained so as to ensure that people do not inhale or ingest it. [143]
Charlie Steen was born in 1919 in Caddo, Stephens County, Texas, the son of Charles A. and Rosalie Wilson Steen, and attended high school in Houston.As a teen Steen worked summers for a construction company that helped finance his education; this is the same company that his first stepfather Lisle had died working at.

Obtained by irradiating uranium with neutrons, it was the first transuranium element discovered. [179] Shortly before that, Yoshio Nishina and Kenjiro Kimura discovered the uranium isotope 237 U and found that it beta decays into 237 93, but were unable to measure the activity of the element 93 product because its half-life was too long.
The discovery of the neutron by James Chadwick in 1932 created a new means of nuclear transmutation. Enrico Fermi and his colleagues in Rome studied the results of bombarding uranium with neutrons, and Fermi concluded that his experiments had created new elements with 93 and 94 protons, which his group dubbed ausenium and hesperium.
Did a Tri-Cities scientist eat radioactive uranium in the ‘80s to prove that it is harmless?. Maybe, says a recent new fact check by Snopes.com. Galen Winsor was a Richland nuclear chemist who ...
By July 1943, the Ames Project was producing 130,000 pounds (59,000 kg) of uranium metal per month. [46] The cost of a pound of uranium metal fell from $1,000 to around one dollar. [47] Starting in July 1943, Mallinckrodt, Electromet, and DuPont began producing uranium by the Ames process, [46] and Ames phased out its own production by early ...
