Edwin McMillan earns his MS in Physics at California Institute of Technology.

McMillan has the idea of "phase stability" which leads to the development of the synchroton and synchro-cyclotron. The synchrocyclotron would adjust the frequency of the accelerating charged particles to adapt to this change in mass and allow for much more energetic particles.

Edwin McMillan dies in El Cierrito of diabetes complications.

McMillan, with P. H. Abelson, discovers neptunium while conducting a fission experiment of uranium-239 with neutrons. Neptunium is the first of many transuranium elements that provide relevant nuclear fuels and contribute significantly to the knowledge of chemistry and nuclear theory. McMillan realizes the underlying principle of the reaction and starts to bombard uranium-239 with deuterium to create the element 94. He moves to MIT and G. T. Seaborg to finish the work of finding plutonium.

Edwin McMillan serves at the Manhattan District, Los Alamos where he conducts implosion research.

Edwin McMillan receives half of the Nobel Prize in Chemistry along with Glenn T. Seaborg "for their discoveries in the chemistry of the transuranium elements".

Edwin McMillan earns his Ph.D. in Physics at Princeton University with a dissertation on the field of molecular beams.

Edwin McMillan serves at the U. S. Navy Radio and Sound Laboratory, San Diego. Here he gets involved in sonar research.

Edwin McMillan is on leave engaged on national defense research at the Radiation Laboratory of the Massachusetts Institute of Technology. Here he gets involved in the radar project.

Edwin McMillan is a member of the General Advisory Committee to the U.S. Atomic Energy Commission.

McMillan is National Research Fellow at University of California. He works on the calculation of the magnetic moment of the proton by a molecular beam method. In 1935 he is Staff Member at Radiation Laboratory under E.O. Lawrence. He helps in the design and construction of cyclotrons. He becomes Instructor in 1935, Assistant Professor in 1936, Associate Professor in 1941 and Professor in 1946. He is Associate Director from 1954-1958, then Deputy Director and finally Director, in the same year.

Edwin McMillan enters the California Institute of Technology where he earns his BS in Physics. Here he is influenced by Linus Pauling, future Nobel laureate in Chemistry for his research into the nature of the chemical bond.

Edwin McMillan is born in Redondo Beach, California to Dr. Edwin Harbaugh McMillan, a physician, and his wife, Anne Marie Mattison. McMillan spends his early years in Pasadena, California.

Edwin McMillan attends Pasadena High School. During high school he spends a lot of time around laboratories and attending public lectures and seminars.
