Albert Ghiorso (b. 15 July 1915) is an American nuclear scientist who helped discover several chemical elements on the periodic table. July 15 is the 196th day (197th in leap years) of the year in the Gregorian Calendar, with 169 days remaining. ... 1915 (MCMXV) was a common year starting on Friday (see link for calendar). ... A chemical element, often called simply element, is a chemical substance that cannot be divided or changed into other chemical substances by any ordinary chemical technique. ... The periodic table of the chemical elements is a tabular method of displaying the chemical elements, first devised in 1869 by the Russian chemist Dmitri Mendeleev. ...

He was born in Vallejo, California and grew up in Alameda, California. As a teenager, he built radio circuitry and earned a reputation for reaching radio frequency distances that outdid the military. Vallejo is a city located in Solano County, California. ... The city of Alameda highlighted within Alameda County Alameda is a city located in Alameda County, California. ...

He received his bachelor's degree in electrical engineering from the University of California, Berkeley in 1937. After graduation, he worked for a company that produced emergency communication devices, and invented the world's first commercial Geiger counter, which evolved into his participation in the Manhattan Project.

He was introduced to Glenn T. Seaborg through a mutual friendship between their wives who also worked as secretaries at the Berkeley Radiation Laboratory. (Likewise, Helen Griggs-Seaborg was Ernest Orlando Lawrence's secretary when she met Glenn Seaborg. ) Glenn T. Seaborg Glenn Theodore Seaborg (April 19, 1912 – February 25, 1999) was an American chemist, who was prominent in the discovery and isolation of many transuranic elements (including plutonium, during the Manhattan Project), for which he won the Nobel Prize in Chemistry in 1951. ... The Berkeley Lab is perched on a hill overlooking the Berkeley central campus and San Francisco Bay. ... Ernest Orlando Lawrence (August 8, 1901 - August 27, 1958) was an American physicist and Nobel laureate best known for his invention of the cyclotron. ... Glenn Theodore Seaborg (April 19, 1912 – February 25, 1999) was an American atomic scientist. ...

Seaborg and Ghiorso's collaboration was most fruitful in the early days of the cyclotron, when its reuslts were hard to identify and detect. Their work resulted in many elements being discovered at UC Berkeley, and Ghiorso is credited with having co-discovered the following elements: 60-inch cyclotron, circa 1939, showing beam of accelerated ions (perhaps protons or deuterons) escaping the accelerator and ionizing the surrounding air causing a blue glow. ...
