## Education

He conducted early research in the Manhattan Project. George served 39 years at Los Alamos National Laboratory as director of chemistry, associate director of research and senior laboratory fellow. He participated in founding the Santa Fe Opera in 1953. He founded the Los Alamos National Bank in 1963 to provide a means to obtain housing for Los Alamos employees and served for 30 years as its chair. He was also the driving influence in founding the Santa Fe Institute together with Nobel Prize winner Murray Gell-Mann and others in 1984, based upon his recognition of the need for a place where scientists could be offered a broader curriculum for the development of "a kind of twenty-first century Renaissance man" and associated research. A graduate of Worcester Polytechnic Institute (bachelor of science in Chemistry) and Carnegie Institute of Technology (doctorate of science), Princeton University, and the University of Chicago, he worked on the top secret Manhattan Project at Los Alamos during World War II. He received the Enrico Fermi Award for "a lifetime of exceptional achievement in the development and use of energy," the New Mexico Academy of Science Distinguished Scientist Award, the Robert H. Goddard Award, the E.O. Lawrence Award, and the Los Alamos National Laboratory Medal, which is the highest honor the Laboratory bestows upon an individual or small group.

## Biography

Cowan was born in Worcester, Massachusetts. In 1941, at the age of twenty one, after graduating from Worcester Polytechnic Institute in chemistry, he worked on the cyclotron project at Princeton University with the intention of taking graduate courses in physics. He worked there with future Nobel Prize Laureate Eugene Wigner, who would design the first uranium chain reactor. In 1941, George participated in taking measurements essential to determining whether the chain reaction in uranium could be achieved. His knowledge of chemistry and nuclear physics experience provided expertise on a number of things necessary to the Manhattan Project. In 1942, Wigner, Cowan, and several others transferred to the Metallurgy Lab at the University of Chicago where the first atomic pile was being developed under Enrico Fermi. Starting as a junior member, Cowan became a jack-of-all-trades, capable of such skills as machining graphite blocks used for control of the pile's reaction rate and in casting uranium metal. In 1942, the Chicago Pile 1 (CP-1) generated the first controlled nuclear reaction. This controlled release of energy from the nucleus of the atom enabled development of a method to obtain nuclear fuel for the first atomic weapons. His experience made him one of the experts on the chemistry of radioactive elements in the field of applied nuclear fission. Since he was single and in possession of high expertise, project managers transferred him around the nation to help resolve bottlenecks. He was one of the select group with knowledge of the separate components of the project, kept separate for security reasons. He received a draft deferment from the president of the United States for possessing skills uniquely useful to the war effort.

## Career

Following the end of the war and obtaining his PhD in physical chemistry from Carnegie Tech, Cowan returned to work for Los Alamos in 1950. Only weeks after his arrival, he directed the detection of radioactive fallout from samples collected near the Russian border indicating the Soviets were in possession of a nuclear bomb. He also participated for some years in the Bethe Panel, whose first chairman was Hans Bethe. One of his early participatory functions on the panel was to convince U.S. government officials that the radiochemistry of the samples proved that it was not the result of a peaceful nuclear reactor problem, but a Soviet bomb, which was dubbed "Joe-1" after Joseph Stalin .

In 1953, Cowan was a member of the group which founded the Santa Fe Opera. Another member of this group was Arthur Spiegel, of the Spiegel Catalog fortune.[citation needed] Art was later to help Cowan in his initial fund raising efforts to finance the Santa Fe Institute.

In 1982, Cowan accepted a seat on the White House Service Council. While serving in this capacity and facing problems involving interlinked aspects of science, policy, economics, environment and more, he realized that this demanded a broad range expertise above the current reductionist approach and fragmentation of the sciences. He believed that our educational culture was enforcing intellectual fragmentation through conservative university programs that depended on specialized grants and funded work. It seemed that cross-disciplinary team efforts were discouraged by membership in traditional, isolated science and social science disciplines. He knew that beginning in the 1980s numerical experiments through computer simulations were capable of providing the tools to think about very complex problems in a more holistic fashion. He began to imagine a new and independent type of institute that would combine the charter of a university while sharing some of Los Alamos' personnel and computer power. This could be a place where senior researchers would have a place to work on very speculative ideas. Where one could educate a man starting in science, but that could deal with the real messy world, which is not elegant, which science doesn't really deal with. In 1983, Cowan assembled a group of senior scientists interested in researching complex, adaptive systems. One year later, this assembly became the Santa Fe Institute. Initial funding came from the National Science Foundation, the Department of Energy, Citicorp and others. George was enthusiastic about complex systems, which he declared to be the next major thrust in science. The Santa Fe Institute fosters interdisciplinary research between physicists, mathematicians, economists, computer scientists, and others. Although most of his duties as president did not allow time for research, as Distinguished Fellow of the Institute, Cowan applied neuroscience principles to investigate relationships between children's brain physiological changes and behavioral development.

## Later life

In 1988, Cowan became a senior fellow emeritus at Los Alamos, a member of a group of six longtime Los Alamos employees rewarded with research positions free from administrative chores that would also advise the laboratory director on policy issues. Cowan served as president of the Santa Fe Institute until his retirement in 1991.

## Death

Cowan died on April 20, 2012, from complications of pneumonia in his Los Alamos home.
