Owen Chamberlain

In 1943, he tied nuptial knot with Beatrice Babette Copper. They were the parents of three daughters and a son whose names were Karen Chamberlain, Lynne Guenther, Pia Chamberlain and Darol. They got divorced in 1978.

In 1980, he got married to June Steingart Greenfield . His third wife was Senta Pugh Gaiser. He had two step-daughters namely Mary Pugh and Anne Pugh. In 1985, he was under medical treatment as he was suffering from Parkinson’s disease.

He retired from teaching in 1989. He was one of 21 Nobel Laureates who signed the Humanist Manifesto in 2003.

Owen Chamberlain was born on July 10, 1920, in San Francisco, California, to W. Edward Chamberlain and Genevieve Lucinda Chamberlain. His father was a radiologist at Stanford University Hospital.

After shifting with his family to Philadelphia, Pennsylvania, he studied at Germantown Friends School. He received his bachelor degree in science from Dartmouth College, New Hampshire in 1941.

Later, he attended the University of California at Berkley. During this time, he came in contact with famous physicist Emilio Segre. When the US joined the World War II in 1942, his studies were interrupted.

In the same year, he became a part of the Manhattan Project, the secret program of the United States to build an atom bomb. At that time, he started working with Segre as part of this project.

His works in this project included to pursue research on uranium isotopes, nuclear cross sections for intermediate energy neutrons and spontaneous fission of heavy elements.

In 1955, he took part in a research project to discover antiproton with Dr. Wiegand, Professor Segre and Dr. Ypsilantis. For this purpose, they utilized bevatron as a powerful particle accelerator.

As part of the project, he studied the interactions of anti-protons with hydrogen, deuterium and other elements. His research work also included the production of antineutrons with the help of antiprotons.

In 1957, he received Guggenheim Fellowship for his research on the physics of antinucleons at the University of Rome. In the next year, he took responsibility of the Professor of Physics at the University of California, Berkeley. In 1959, he acted as Loeb Lecturer at Harvard University.

In association with Professors Carson Jeffries and Gilbert Shapiro, he successfully developed polarized proton targets in 1960. This discovery helped in the study of the spin dependence of a number of high energy processes.

In the later part of 1970s, he took part in the study of the interactions of energetic light nuclei with nuclear targets at the Berkeley Bevalac accelerator for a short period.

In 1959, he received the prestigious Nobel Prize in Physics for his discovery of antiprotons. These antiprotons are the antiparticles of the protons and are also known as negatrons. He shared this award with Emilio Segre.
