J. Barton Hoag was born in Colorado Springs, Colorado on September 22, 1898. He received his A.B. from Colorado College in 1920. Hoag was an instructor of physics at Colorado College from 1920 until 1921. He earned his Ph.D. from the University of Chicago in 1927. Hoag was on the physics faculty at the University of Chicago from 1922 to 1940. He went on to be part of the science faculty and the head of the Science Department at the United States Coast Guard Academy from 1940 until 1960. After he retired from the Academy, he spent two years teaching at the University of Florida. Throughout his career, Hoag studied extreme ultraviolet spectroscopy and electron and nuclear physics. He was also a prolific creator of demonstration lectures in physics. Hoag died in 1962.

 Scope and Contents of Collection

The papers of J. Barton Hoag span from 1914-1962, with the bulk of the collection between 1917 and 1962. The collection contains student notebooks (1917-1924) from his years at Colorado College and the University of Chicago. Some of the courses were taught by Arthur J. Dempster, Albert A Michelson and Robert A. Millikan. Hoag's undergraduate and Ph.D. theses are also included. The lecture notes (1926-1962) are from courses Hoag taught at the University of Chicago, University of Florida and the Coast Guard Academy. There are copies of the theses Hoag directed while teaching at the University of Chicago. The manuscript materials consist of drafts of books and articles. The subject files consist of notes, reference notes and typescripts of various topics. The reprints (1927-1948) are of articles by Hoag. The other reprints (1914-1963) are by colleagues. The correspondence (1929-1962) concerns apparatus, the Michelson Museum at China Lake, and two books by Hoag: Electron Physics and Basic Radio. According to Mrs. Patricia Hoag, many of the notes and data that originally accompanied these papers were destroyed in 1963. Mrs. Hoag went through the papers with two physicists and was told that "no one could read, much less use another man's notes." What remained after this process is what is contained in this collection. Correspondents include: Adrian N. Clark, Edward M. Crane, Glenn M. Hobbs, Julian E. Mack, Robert A. Millikan, Thomas C. Poulter, and Morton H. Teller.

 Organization of Collection

The collection is organized into 13 series: I. Correspondence, 1929-1962; II. Student Notebooks, 1917-1924; III. Theses, 1921-1927; IV. Lecture Notes, 1926-1962; V. Theses Directed by Hoag, 1929-1939; VI. Manuscripts of books, articles, essays and addresses; VII. Hoag reprints, 1927-1948; VIII. Reprints, magazines, etc., 1914-1963; IX.
