Two versions of Randall's autobiography: an early ten-page version and a later revised manuscript of 23 pages. In both, Randall describes his childhood and early education in Burr Oak, Dundee, and Ann Arbor, MI, and his undergraduate and graduate education at the University of Michigan, from which he graduated in 1893 with an M.Phil. Randall then describes his teaching experiences in Bay City and Saginaw, MI, where he married, and his return to the the University of Michigan for his Ph.D., which he completed in 1905. Randall discusses his thesis on temperature measurement in some detail; the earlier manuscript ends with his Ph.D. studies. The revised manuscript continues with a detailed discussion of his studies in infrared spectroscopy with Friedrich Paschen at Eberhard-Karls-Universitt̃ T bingen beginning in 1910. He also discusses: University of Michigan summer school sessions and their participants and faculty, theoretical physics between the two World Wars and his position on the University of Michigan faculty, his work in synthesizing penicillin during World War II, and the difficulties involved in being head of an academic department.
