Norman C. Rasmussen was an American physicist
Physicist
A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

. He grew up on a dairy farm as the fifth of six brothers. He attended public school in Hershey, Pennsylvania. His father died when he was in eighth grade, and his family moved to Gettysburg, where his grandparents helped to care for the family. Rasmussen graduated from high school in June, 1945 and enlisted in the Navy. He was sent to Great Lakes Naval Training school, where he became and electronics technician He served on active duty until August, 1946, when he was honorably discharged.

Norm enrolled in Gettysburg College in the fall of 1946, using the GI bill to finance his tuition. He majored in Physics, and studies under Professor George Miller

, who encouraged Norm to go to Graduate School. At Gettysburg he also met his future wife, Thalia Tichenor. They married in 1952.

He graduate from Gettysburg College cum laude in 1950 and enrolled as a graduate student in the Physics Department at MIT. He worked for Professor Robley Evans in the Radioactivity Center, which Evans had created and led. The work was concerned with the field of experimental low-energy nuclear physics, including the determination of nuclear energy levels, radiation dosimetry, and the biological effects of radiation. He worked as a teaching assistant for Professor Evans' two semester undergraduate course "Nuclear Physics" in 1952.

Rasmussen completed his Ph.D. in 1956 with the graduate thesis entitled "Standardization of Electron Capture Isotopes." After graduation, he remained in the Physics Department as an instructor. He also continued his experimental work at The Radioactivity Center. In the 1950s, the tools available for detection and measurement were relatively primitive. Norm was in the forefront of developing coincidence-counting techniques to measure decay schemes.

MIT began construction of their first research reactor, led by Norm's good friend Theos J. Thompson, to be competed in 1958. That same year, Course XXII was upgraded to a full MIT academic department (previously it was a program under Chemical Engineering), Norm as invited by Manson Benedict

A spectrometer is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light's intensity but could also, for instance, be the polarization...

 used for gamma ray spectroscopy studies for many years. He migrated from determination of decay spectra to the use of spectra for measuring nuclear composition. This led him to a major program for the measurement of spent nuclear fuel composition, a matter of significant importance to the nuclear weapons programs where both tritium and plutonium were created in production reactors. the International Atomic Energy Agency

 adopted his techniques for use in proliferation studies.

His initial research concentrated on investigating radiation and gamma rays. He was the head of the nuclear engineering department from 1975 to 1981. He headed the landmark Reactor Safety Study (WASH-1400) in the early 1970s. This study established the formal discipline of Probabilistic Risk Assessment

 (1979), as well as serving a 6-year term on the National Science Board during the Reagan Administration. Professor Rasmussen won the Enrico Fermi Award for excellence in the field of nuclear energy in 1985 for his ‘pioneering contributions to nuclear energy in the development of probabilistic risk assessment techniques that have provided new insights and led to new developments in nuclear power plant safety. Perhaps his most remembered moment was his televised debate with activist Ralph Nader over the safety of nuclear power.
