Homer Dupre Hagstrum (March 11, 1915 – September 7, 1994) was an American physicist who specialized in surface physics.
He developed a metal multipurpose vacuum chamber in 1961 that is a model for many surface physics scientists today.
In 1942 he and John R Pearce traveled to England to meet with British scientists working on RADAR.
Pearce and Hagstrum also met with Rudy Kompfner during this trip.
Hagstrum was elected a Fellow of the American Physical Society in 1949 [3] and a member of the National Academy of Sciences in 1976.
