Bernard Gottschalk

Bernard.(Bernie) Gottschalk started the nuclear physics research program at the Harvard Cyclotron Laboratory (HCL) in 1955, obtained his Ph.D. in 1962, and remained as a postdoctoral fellow until 1965. He joined groups working at Fermilab and Cern. In 1965 he became a professor at Northeastern University, where he stayed until 1981.

He returned to the HCL (then a medical facility) in 1981 to join the proton therapy group under the direction of Andreas (Andy) Koehler. He remained there to work on the physics of proton radiotherapy, electronics and instrumentation, until HCL closed in 2002.

Bernie was born in 1935 in Germany and at the age of three, his family escaped Nazi Germany and immigrated to New York City.

He is credited with being the first to observe proton-proton Bremsstrahlung.
