Norman Hilberry (March 11, 1899 – March 28, 1986) was an American physicist, best known as the director of the Argonne National Laboratory from 1956 to 1961. In December 1942 he was the man who stood ready with an axe to cut the scram line during the start up of Chicago Pile-1, the world's first nuclear reactor to achieve criticality. Biography Horace van Norman Hilberry was born in Cleveland, Ohio, on March 11, 1899. He received his Bachelor of Arts (A.B.) degree from Oberlin College in 1921, and then became an assistant in physics at the University of Chicago. In 1925 he became an instructor in physics at Washington Square College in New York, where he rose to become an assistant professor in 1928. He earned his Doctor of Philosophy (Ph.D.) from the University of Chicago in 1941, writing his thesis on "Extensive cosmic-ray showers and the energy distribution of the primary cosmic rays". In 1941, Hilberry joined what would become the Manhattan Project, the effort to create ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leo Szilard
Leo Szilard (; hu, Szilárd Leó, pronounced ; born Leó Spitz; February 11, 1898 – May 30, 1964) was a Hungarian-German-American physicist and inventor. He conceived the nuclear chain reaction in 1933, patented the idea of a nuclear fission reactor in 1934, and in late 1939 wrote the letter for Albert Einstein's signature that resulted in the Manhattan Project that built the atomic bomb. According to György Marx, he was one of the Hungarian scientists known as The Martians. Szilard initially attended Palatine Joseph Technical University in Budapest, but his engineering studies were interrupted by service in the Austro-Hungarian Army during World War I. He left Hungary for Germany in 1919, enrolling at Technische Hochschule (Institute of Technology) in Berlin-Charlottenburg, but became bored with engineering and transferred to Friedrich Wilhelm University, where he studied physics. He wrote his doctoral thesis on Maxwell's demon, a long-standing puzzle in the ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Professor Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...

Albert Crewe
Albert Victor Crewe (February 18, 1927 – November 18, 2009) was a British-born American physicist and inventor of the modern scanning transmission electron microscope capable of taking still and motion pictures of atoms, a technology that provided new insights into atomic interaction and enabled significant advances in and had wide-reaching implications for the biomedical, semiconductor, and computing industries. Early life and education Crewe was born in Bradford, England, in 1927 and grew up during World War II in a blue collar community still recovering from the worldwide depression. The family was poor and expectations were limited. He had average grades in school but passed two nationwide examinations, the first of which enabled him to become the first in his family to attend high school and the second of which allowed him to attend college. He attended Carlton Grammar School, in the south-east of Bradford, since 1977 called Carlton Bolling College. He won a military sc ...

Atoms For Peace
"Atoms for Peace" was the title of a speech delivered by U.S. President Dwight D. Eisenhower to the UN General Assembly in New York City on December 8, 1953. The United States then launched an "Atoms for Peace" program that supplied equipment and information to schools, hospitals, and research institutions within the U.S. and throughout the world. The first nuclear reactors in Israel and Pakistan in Islamabad were built under the program by American Machine and Foundry, a company more commonly known as a major manufacturer of bowling equipment. Philosophy The speech was part of a carefully orchestrated media campaign, called " Operation Candor", to enlighten the American public on the risks and hopes of a nuclear future. Both Operation Candor and Atoms for Peace were influenced by the January 1953 report of the State Department Panel of Consultants on Disarmament, which urged that the United States government practice less secrecy and more honesty towards the American people ...

Eisenhower Administration
Dwight D. Eisenhower's tenure as the 34th president of the United States began with his first inauguration on January 20, 1953, and ended on January 20, 1961. Eisenhower, a Republican from Kansas, took office following a landslide victory over Democrat Adlai Stevenson in the 1952 presidential election. John F. Kennedy succeeded him after winning the 1960 presidential election. Eisenhower held office during the Cold War, a period of geopolitical tension between the United States and the Soviet Union. Eisenhower's New Look policy stressed the importance of nuclear weapons as a deterrent to military threats, and the United States built up a stockpile of nuclear weapons and nuclear weapons delivery systems during Eisenhower's presidency. Soon after taking office, Eisenhower negotiated an end to the Korean War, resulting in the partition of Korea. Following the Suez Crisis, Eisenhower promulgated the Eisenhower Doctrine, strengthening U.S. commitments in the Middle East. In re ...

Metallurgical Laboratory
The Metallurgical Laboratory (or Met Lab) was a scientific laboratory at the University of Chicago that was established in February 1942 to study and use the newly discovered chemical element plutonium. It researched plutonium's chemistry and metallurgy, designed the world's first nuclear reactors to produce it, and developed chemical processes to separate it from other elements. In August 1942 the lab's chemical section was the first to chemically separate a weighable sample of plutonium, and on 2 December 1942, the Met Lab produced the first controlled nuclear chain reaction, in the reactor Chicago Pile-1, which was constructed under the stands of the university's old football stadium, Stagg Field. The Metallurgical Laboratory was established as part of the Metallurgical Project, also known as the "Pile" or "X-10" Project, headed by Chicago professor Arthur H. Compton, a Nobel Prize laureate. In turn, this was part of the Manhattan Project – the Allied effort to develop the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanford Engineer Works
The Hanford Engineer Works was a nuclear production complex established by the United States federal government in 1943 as part of the Manhattan Project during World War II. The site, located at the Hanford Site on the Columbia River in Benton County, Washington, was home to the B Reactor, the first full-scale plutonium production reactor. Plutonium manufactured at the site was used in the first atomic bomb in the Trinity test, and in the Fat Man bomb that was used in the atomic bombing of Nagasaki in August 1945. It was commanded by Colonel Franklin T. Matthias until January 1946, and then by Colonel Frederick J. Clarke. Plutonium was a rare element that had only recently been isolated in the laboratory, but it was theorized that it could be produced by the irradiation of uranium in a nuclear reactor and used in an atomic bomb. The director of the Manhattan Project, Brigadier General Leslie R. Groves Jr., engaged DuPont to be the prime contractor for the design, construct ...
