Leon Pape (February 8, 1925 – January 2, 1984) was a medical physicist who received his BSc, MSc (1953) and PhD (1965) in Physics from the University of Southern California.^[1][2][3] He became certified in radiological physics by the American Board of Radiology and from 1955 to 1962 he worked as a radiological physicist at the Cedars of Lebanon Hospital in Los Angeles. He served at the California State University Los Angeles as radiation safety officer and as professor of physics until 1971, and worked on the development of studies in biophysics, radiological health physics, and electron microscopy. He was elevated to departmental head of physics at Cal State Los Angeles, and advocated with the California legislature to secure adequate funding for the 4-MeV Van de Graaf Laboratory, unique to CSU system. From 1971 until his death he worked at the August Krogh Institute at the University of Copenhagen, Denmark, in the zoophysiological laboratory. His central research area was membrane biophysics.^[4]

The Leon Pape Memorial Lecture Series was inaugurated by CSU after his "untimely death in January 1984 prompted the establishment of this lecture series in his memory, encompassing his many interests."^[8] The award of this Lectureship is highly prestigious,^{[citation needed]} with many Nobel Laureates and prominent academics having delivered it since its inception.
