J. Ernest Wilkins Jr.

Wilkins died on May 1, 2011 in Fountain Hills, Arizona. He was buried at the National Memorial Cemetery, Cave Creek, Arizona on May 5.

Wilkins is the uncle of two notable attorneys: David B. Wilkins, a professor at the Harvard Law School, and Timothy A. Wilkins, a partner with Freshfields Bruckhaus Deringer. In 2010 a niece of Wilkins, Carolyn Marie Wilkins, Professor of Music at the Berklee College of Music in Boston, wrote of Wilkins' father and her family more generally in her biography Damn Near White: An African American Family's Rise from Slavery to Bittersweet Success.

From 1990 Wilkins lived and worked in Atlanta, Georgia as a distinguished professor of applied mathematics and mathematical physics at Clark Atlanta University, and retired again for his last time in 2003.

Wilkins had two children with his first wife Gloria Louise Steward (d.1980) whom he married in June 1947, married Maxine G. Malone in 1984. He was married a third time to Vera Wood Anderson in Chicago in September 2003. He had a daughter, Sharon, and a son, J. Ernest III, during his first marriage.

Wilkins and Eugene Wigner co-developed the Wigner-Wilkins approach for estimating the distribution of neutron energies within nuclear reactors, which is the basis for how all nuclear reactors are designed. Wilkins later went on to become the President of the American Nuclear Society in 1974.

From 1974 to 1975 Wilkins served as president of the American Nuclear Society and in 1976 became the second African American to be elected to the National Academy of Engineering.

In 1970 Wilkins went on to serve Howard University as its distinguished professor of applied mathematical physics and also to help found the university's PhD program in mathematics. During his tenure at Howard he undertook a sabbatical position as a visiting scientist at Argonne National Laboratory from 1976 to 1977.

To improve communication between mathematicians and nuclear engineers on a project, Wilkins earned bachelor's (1957) and master's degrees (1960) in mechanical engineering from New York University, thus earning five science degrees during his life. It also qualified him to design and build nuclear facilities.

In 1944 he returned to the University of Chicago where he served first as an associate mathematical physicist and then as a physicist in its Metallurgical Laboratory, as part of the Manhattan Project. Working under the direction of Arthur Holly Compton and Enrico Fermi, Wilkins researched the extraction of fissionable nuclear materials, but was not told of the research group's ultimate goal until after the atomic bomb was dropped on Hiroshima. Wilkins was the co-discoverer or discoverer of a number of phenomena in physics such as the Wilkins effect and the Wigner–Wilkins spectra.

When Wilkins's team was about to be transferred to the Oak Ridge National Laboratory in Oak Ridge, Tennessee (known at the time as site "X"), due to the Jim Crow laws of the Southern United States, Wilkins would have been prevented from working there. When Edward Teller was informed about this, he wrote a letter on September 18, 1944, to Harold Urey (who was the director of war research at Columbia at the time) of Wilkins's abilities, informing him about the issue caused by local reactions to Wilkins's race, and recommending his services for a new position.

Having initially been unable to secure a research position, Wilkins taught mathematics from 1943 to 1944 at the Tuskegee Institute (now Tuskegee University) in Tuskegee, Alabama.

In 1940, Wilkins completed his AB in mathematics at the University of Chicago. He went on to an MS and PhD in mathematics at the same institution, which he completed in 1941 and 1942.

Jesse Ernest Wilkins Jr. (November 27, 1923 – May 1, 2011) was an African American nuclear scientist, mechanical engineer and mathematician. A child prodigy, he attended the University of Chicago at the age of 13, becoming its youngest ever student. His graduation at a young age resulted in him being hailed as "the Negro Genius" in the national media.
