In 1929, Feenberg graduated from the University of Texas at Austin in three years, first in his class; he majored in physics and mathematics. Upon the urging of one of his professors, C. P. Boner, Feenberg then went to Harvard University to study with Edwin C. Kemble for a doctorate in physics. While at Harvard, during 1930 and 1931, he also worked part-time at a Raytheon laboratory, as the Great Depression was in full swing. In 1931, Harvard awarded him a Parker Traveling Fellowship; he left for Europe in the fall of that year. During his stay in Europe, he studied with Arnold Sommerfeld at the Ludwig Maximilians University of Munich, Wolfgang Pauli at the Eidgenössische Technische Hochschule Zürich, and Enrico Fermi at the University of Rome.
Adolf Hitler had been appointed Chancellor in January 1933 and Feenberg was in Leipzig in the spring of that year. He wrote to Kemble of the persecution taking place and the violence in the streets. Harvard called Feenberg back to the Harvard campus, where he finished his doctorate under Kemble in 1933; his thesis was on quantum scattering of slow electrons by neutral atoms. For the next two years at Harvard, he took a position as an instructor and worked on the theory of nuclear forces and structure. During this time at Harvard, he also contributed to advancing quantum theory, as Kemble, in the original 1937 edition of his book on the subject, thanked his former colleague Feenberg, along with others for suggestions and assistance.
In 1935, Feenberg went to the University of Wisconsin–Madison for a year, where he continued his work on nuclear structure and energy levels. In 1936, he collaborated with Gregory Breit and published a paper on the charge independence of nuclear forces. There, he also met Eugene Wigner and they collaborated on work which resulted in a paper published in 1937 on the structure of nuclei from helium to oxygen, showing the importance of the symmetry of the wave function in binding p-shell nuclei.
From 1936 to 1938, Feenberg was at the Institute for Advanced Study in Princeton, New Jersey. There he continued his work on the nuclear p-shell, some of it in collaboration with Melba Phillips; their work was published in 1937.
On recommendations from Wigner, Kemble, and I. I. Rabi, New York University hired Feenberg for its Washington Square College, where he would eventually rise to the rank of associate professor. During World War II, while he was sought to work at Los Alamos, he took leave of absence to work on radar at the Sperry Gyroscope Company where he advance the theory of klystron tubes.
After the War, in 1946, Feenberg was hired by Washington University in St. Louis as associate professor, eventually rising to full professor. There, he drew on his studies of isomerism and nuclear structure and the nature of beta-decay transitions to provide the foundations for building a modern shell theory of the nucleus. This work resulted in his second book published in 1955. His first book had been published two year earlier, 1953, with George Pake, who had just become head of the physics department the year before at age 28. His third book, on quantum fluids, was published in 1967, and his collected papers were published in 1975. Feenberg became the Wayman Crow Professor of Physics in 1964, a position he held until becoming professor emeritus in 1975.
While at Washington University, Feenberg was Visiting Higgins Professor of Physics at Princeton University (1953-1954), visiting professor of physics at the State University of New York at Stony Brook (spring semester 1969), and lecturer at Escuela Latino Americana de Fisica, Universidad Nacional Autonoma de Mexico (July 1–19, 1974).
Feenberg died on November 7, 1977.
