Description
This collection contains correspondence, teaching materials, subject files, and research notes of Karl R. Spangenberg relating
to his work as an electircal engineer specilizing in vacuum tubes at Stanford.
Background
Karl Spangenberg (1910-1964) served as a Professor of Electrical Engineering at Stanford. He was a member of the American
Physical Society and became an IRE (now IEEE) Associate in 1934, Senior Member in 1945, and Fellow in 1949. He was an adviser
of numerous scientists at Stanford University, including Willis Harman, Robert Helliwell, and Chih-Tang Sah. During the later
years of World War II, 1944-1945, Spangenberg served as a technical consultant for the United States Office of Scientific
Research and Development. After being awarded a Medal of Freedom from President Truman, he headed the Electronics Division
of the Office of Naval Research from 1948-1949. In 1952 to 1954, he and his family lived in the state of Sao Paulo, Brazil,
where he worked as Head of the Electronic Engineering Department of the Instituto Technologica de Aeronautica, the Brazilian Air Force Institute/Academy. In the early 1960s, Spangenberg was a consultant on engineering management and
education to various companies, primarily in the San Francisco Bay area. During his life, he published two books on the subject
of electrical engineering, Vacuum Tubes(1948) and Fundamentals of Electron Devices. Spangenberg's last book, Electromagnetics in Space: Antenna Considerations as Related to Space Communications(1965), he edited was published posthumously.
