This dissertation reveals how Joseph Henry's teaching related to his research, and how it reflected his overall scientific outlook and affected developments in physics.

In this dissertation Saunders shows that Einstein's "1905 theory" restricts the number of permissible models of an ether.

The bulk of the material in this collection pertains to the years Bazzoni spent at the University of Pennsylvania (BA 1911, PhD 1914). There are three notebooks filled with student lecture notes from the years 1913-1914. Also, a collection of articles Bazzoni wrote while teaching at Pennsylvania, including several memos to the Educational Survey Committee. There is a notebook tracking his experiments while in London at King's College, and copies of two dissertations by students, presumably from the years Bazzoni was at Pennsylvania. Materials from the post-Pennsylvania years is limited to a notebook of Potential Center Displacement of Logger Tests.
