Provenance: Pief Panofsky. Wolfgang Kurt Hermann "Pief" Panofsky (April 24, 1919 – September 24, 2007), was a German-American physicist who won many awards including the National Medal of Science. Panofsky was born in Berlin, Germany to a family of art historians Dorothea and Erwin Panofsky. His ancestors were of Jewish descent. He spent much of his early life in Hamburg, where his father was a professor of art history. From the age of 10, he attended the Johanneum, where he received a classical education involving Latin and Ancient Greek, but little science. At the age of 15, he moved with his family to the United States and entered Princeton University. He graduated with an A.B. in physics from Princeton University, as salutatorian of his class, in 1938 after completing a senior thesis, titled "The construction of a high pressure ionisation chamber", under the supervision of Walker Bleakney. He then received his Ph.D. in physics from the California Institute of Technology in 1942 after completing a doctoral dissertation, titled "A measurement of the value of h/e by the determination of the short wavelength limit of the continuous x-ray spectrum at 20 kV", under the supervision of Jesse W. M. DuMond. In April 1942 he was naturalized as a U.S. citizen.
