Career

Shockley was one of the first recruits to Bell Labs by Mervin Kelly, who became director of research at the company in 1936 and focused on hiring solid-state physicists. Shockley joined a group headed by Clinton Davisson in Murray Hill, New Jersey. Executives at Bell Labs had theorized that semiconductors may offer solid-state alternatives to the vacuum tubes used throughout Bell's nationwide telephone system. Shockley conceived a number of designs based on copper-oxide semiconductor materials, and with Walter Brattain unsuccessfully attempted to create a prototype in 1939.

Shockley published a number of fundamental papers on solid state physics in Physical Review. In 1938, he received his first patent, "Electron Discharge Device", on electron multipliers.

When World War II broke out, Shockley's prior research was interrupted and he became involved in radar research in Manhattan (New York City). In May 1942, he took leave from Bell Labs to become a research director at Columbia University 's Anti-Submarine Warfare Operations Group. This involved devising methods for countering the tactics of submarines with improved convoying techniques, optimizing depth charge patterns, and so on. Shockley traveled frequently to the Pentagon and Washington to meet high-ranking officers and government officials.

In 1944, he organized a training program for B-29 bomber pilots to use new radar bomb sights. In late 1944 he took a three-month tour to bases around the world to assess the results. For this project, Secretary of War Robert Patterson awarded Shockley the Medal for Merit on October 17, 1946.

In July 1945, the War Department asked Shockley to prepare a report on the question of probable casualties from an invasion of the Japanese mainland. Shockley concluded:

If the study shows that the behavior of nations in all historical cases comparable to Japan's has in fact been invariably consistent with the behavior of the troops in battle, then it means that the Japanese dead and ineffectives at the time of the defeat will exceed the corresponding number for the Germans. In other words, we shall probably have to kill at least 5 to 10 million Japanese. This might cost us between 1.7 and 4 million casualties including 400,000 to 800,000 killed.

This report influenced the decision of the United States to drop atomic bombs on Hiroshima and Nagasaki, which preceded the surrender of Japan.

Shockley was the first physicist to propose a log-normal distribution to model the creation process for scientific research papers.
