On This Date In History

On December 2, 1942, Enrico Fermi, the Italian-born Nobel Prize-winning physicist, directs and controls the first nuclear chain reaction in his laboratory beneath the bleachers of Stagg Field at the University of Chicago, ushering in the nuclear age. Upon successful completion of the experiment, a coded message was transmitted to President Roosevelt: “The Italian navigator has landed in the new world.”
Following on England’s Sir James Chadwick’s discovery of the neutron and the Curies’ production of artificial radioactivity, Fermi, a full-time professor of physics at the University of Florence, focused his work on producing radioactivity by manipulating the speed of neutrons derived from radioactive beryllium. Further similar experimentation with other elements, including uranium 92, produced new radioactive substances; Fermi’s colleagues believed he had created a new “transuranic” element with an atomic number of 93, the result of uranium 92 capturing a neuron while under bombardment, thus increasing its atomic weight. Fermi remained skeptical about his discovery, despite the enthusiasm of his fellow physicists. He became a believer in 1938, when he was awarded the Nobel Prize in physics for “his identification of new radioactive elements.” Although travel was restricted for men whose work was deemed vital to national security, Fermi was given permission to leave Italy and go to Sweden to receive his prize. He and his wife, Laura, who was Jewish, never returned; both feared and despised Mussolini’s fascist regime.
Fermi immigrated to New York City, Columbia University, specifically, where he recreated many of his experiments with Niels Bohr, the Danish-born physicist, who suggested the possibility of a nuclear chain reaction. Fermi and others saw the possible military applications of such an explosive power, and quickly composed a letter warning President Roosevelt of the perils of a German atomic bomb. The letter was signed and delivered to the president by Albert Einstein on October 11, 1939. The Manhattan Project, the American program to create its own atomic bomb, was the result.
It fell to Fermi to produce the first nuclear chain reaction, without which such a bomb was impossible. He created a jury-rigged laboratory with the necessary equipment, which he called an “atomic pile,” in a squash court in the basement of Stagg Field at the University of Chicago. With colleagues and other physicists looking on, Fermi produced the first self-sustaining nuclear chain reaction and the “new world” of nuclear power was born.

On December 2, 1823, during his annual address to Congress, President James Monroe proclaims a new U.S. foreign policy initiative that becomes known as the “Monroe Doctrine.” Primarily the work of Secretary of State John Quincy Adams, the Monroe Doctrine forbade European interference in the American hemisphere but also asserted U.S. neutrality in regard to future European conflicts.
The origins of the Monroe Doctrine stem from attempts by several European powers to reassert their influence in the Americas in the early 1820s. In North America, Russia had attempted to expand its influence in the Alaska territory, and in Central and South America the U.S. government feared a Spanish colonial resurgence. Britain too was actively seeking a major role in the political and economic future of the Americas, and Adams feared a subservient role for the United States in an Anglo-American alliance.
The United States invoked the Monroe Doctrine to defend its increasingly imperialistic role in the Americas in the mid-19th century, but it was not until the Spanish-American War in 1898 that the United States declared war against a European power over its interference in the American hemisphere. The isolationist position of the Monroe Doctrine was also a cornerstone of U.S. foreign policy in the 19th century, and it took the two world wars of the 20th century to draw a hesitant America into its new role as a major global power.

On This Date In History

On October 16, 1946, at Nuremberg, Germany, 10 high-ranking Nazi officials are executed by hanging for their crimes against humanity, crimes against peace, and war crimes during World War II.
Two weeks earlier, the 10 were found guilty by the International War Crimes Tribunal and sentenced to death along with two other Nazi officials. Among those condemned to die by hanging were Joachim von Ribbentrop, Nazi minister of foreign affairs; Hermann Göring, founder of the Gestapo and chief of the German air force; Wilhelm Frick, minister of the interior; and Alfred Rosenberg, head of the Reich Ministry for the Occupied Eastern Territories. Others, including Rudolf Hess, Adolf Hitler’s former deputy, were given prison sentences ranging from 10 years to life. Three others were acquitted.
The trial, which had lasted nearly 10 months, was conducted by an international tribunal made up of representatives from the United States, the USSR, France, and Great Britain. It was the first trial of its kind in history, and the defendants faced charges ranging from crimes against peace, to crimes of war and crimes against humanity. On October 16, 10 of the architects of Nazi policy were hanged one by one. Hermann Göring, who at sentencing was called the “leading war aggressor and creator of the oppressive program against the Jews,” died by suicide by poison on the eve of his scheduled execution. Nazi Party leader Martin Bormann was condemned to death in absentia; he is now known to have died in Berlin at the end of the war.

On October 16, 1964, The People’s Republic of China joins the rank of nations with atomic bomb capability, after a successful nuclear test. China is the fifth member of this exclusive club, joining the United States, the Soviet Union, Great Britain and France.
U.S. officials were not terribly surprised by the test; intelligence reports since the 1950s indicated that China was working to develop an atomic bomb, possibly aided by Soviet technicians and scientists. Nevertheless, the successful test did cause concern in the U.S. government. During the early 1960s, China took a particularly radical stance that advocated worldwide revolution against the forces of capitalism, working strenuously to extend its influence in Asia and the new nations of Africa. The test, coming just two months after the Tonkin Gulf Resolution (a congressional resolution giving President Lyndon B. Johnson the power to respond to communist aggression in Vietnam) created a frightening specter of nuclear confrontation and conflict in Southeast Asia.
The test also concerned the Soviet Union; the split between the USSR and communist China over ideological and strategic issues had widened considerably by 1964. The Chinese acquisition of nuclear capabilities only heightened the tensions between the two nations. Indeed, the test might have been a spur to the Soviets to pursue greater efforts to stop the proliferation of nuclear weapons; in 1968, the United States and the Soviet Union signed the Treaty on the Non-Proliferation of Nuclear Weapons. Little wonder that the Soviets would wish to see China’s nuclear force limited, since the first Chinese intermediate-range missiles were pointedly aimed at Russia. The Cold War nuclear arms race had just become a good deal more complicated.

On October 16, 1958, Chevrolet begins to sell a car-truck hybrid that it calls the El Camino. The El Camino was a combination sedan-pickup truck built on the Impala body, with the same “cat’s eye” taillights and dramatic rear fins. It was, ads trilled, “the most beautiful thing that ever shouldered a load!” “It rides and handles like a convertible,” Chevy said, “yet hauls and hustles like the workingest thing on wheels.”
Ford’s Ranchero was the first “car-truck” sold in the United States, it had been on the market for two years already, but it was not a new idea. Since the 1930s, Australian farmers had been driving what they called “utes”, short for “coupé utility”, all around the outback. Legend has it that a farmer’s wife from rural Victoria had written a letter to Ford Australia, asking the company to build a car that could carry her to church on Sundays and her husband’s pigs to market on Mondays. In response, Ford engineer Lewis Brandt designed a low-slung sedan-based vehicle that was a ritzy passenger car in the front, with wind-up windows and comfortable seats and a rough-and-tumble pickup in back. The ute was a huge hit; eventually, virtually every company that sold cars Down Under made its own version.
In the United States, however, ute-type vehicles were slower to catch on. Though the Ranchero was a steady seller, the first incarnation of the El Camino was not and Chevy discontinued it after just two years. In 1964, the company introduced a new version, this one built on the brawnier Chevelle platform. In 1968, the more powerful SS engine made the El Camino into one of the iconic muscle cars of the late 1960s and 1970s.
In 1987, Chevrolet dropped the El Camino from its lineup for good. Today, the car is a cult classic.
