1927 – Following 19 years of Ford Model T production, the Ford Motor Company unveils the Ford Model A as its new automobile.
The Ford Model A of 1928–1931 (also colloquially called the A-Model Ford or the A, and A-bone among rodders and customizers) was the second huge success for the Ford Motor Company, after its predecessor, the Model T. First produced on October 20, 1927, but not sold until December 2, it replaced the venerable Model T, which had been produced for 18 years. This new Model A (a previous model had used the name in 1903–1904) was designated as a 1928 model and was available in four standard colors.
By 4 February 1929, one million Model As had been sold, and by 24 July, two million. The range of body styles ran from the Tudor at US$500 (in grey, green, or black) to the Town Car with a dual cowl at US$1200. In March 1930, Model A sales hit three million, and there were nine body styles available.
The Model A was produced through 1931. When production ended in March, 1932, there were 4,849,340 Model As made in all styles. Its successor was the Model B, which featured an updated 4-cylinder engine, as well as the Model 18 which introduced Ford’s new flathead (sidevalve) V8 engine.
1942 – World War II: During the Manhattan Project, a team led by Enrico Fermi initiates the first self-sustaining nuclear chain reaction.
On 2 December 1942, CP-1 was ready for a demonstration. Before a group of dignitaries, George Weil worked the final control rod while Fermi carefully monitored the neutron activity. The pile “went critical” (reached a self-sustaining reaction) at 15:25. Fermi shut it down 28 minutes later.
After the chain reaction was observed, Arthur Compton, head of the Metallurgical Laboratory, notified James Conant, chairman of the National Defense Research Committee, by telephone. The conversation was in an impromptu code:
Compton: The Italian navigator has landed in the New World.
Conant: How were the natives?
Compton: Very friendly.
Unlike most reactors that have been built since, CP-1 had no radiation shielding and no cooling system of any kind. Fermi had convinced Arthur Compton that his calculations were reliable enough to rule out a runaway chain reaction or an explosion. But, as the official historians of the Atomic Energy Commission later noted, the “gamble” remained in conducting “a possibly catastrophic experiment in one of the most densely populated areas of the nation!”
1970 – The United States Environmental Protection Agency begins operations.
The United States Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the U.S. federal government which was created for the purpose of protecting human health and the environment by writing and enforcing regulations based on laws passed by Congress. The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its Administrator, who is appointed by the president and approved by Congress. The current administrator is Gina McCarthy. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank.
The EPA has its headquarters in Washington, D.C., regional offices for each of the agency’s ten regions, and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tribal, and local governments. It delegates some permitting, monitoring, and enforcement responsibility to U.S. states and the federal recognized tribes. EPA enforcement powers include fines, sanctions, and other measures. The agency also works with industries and all levels of government in a wide variety of voluntary pollution prevention programs and energy conservation efforts.
1982 – At the University of Utah, Barney Clark becomes the first person to receive a permanent artificial heart.
In 1981, William DeVries submitted a request to the FDA for permission to implant the Jarvik 7 into a human being. On December 2, 1982, Kolff implanted the Jarvik 7 artificial heart into Barney Clark, a dentist from Seattle who was suffering from severe congestive heart failure. While Clark lived for 112 days tethered to an external pneumatic compressor, a device weighing some 400 pounds (180 kg), during that time he suffered prolonged periods of confusion and a number of instances of bleeding, and asked several times to be allowed to die.
