<h1>Joseph Henry Collection</h1>
<p>
Joseph Henry served as the first chair of Natural History at Princeton
University (then known as the College of New Jersey). He developed a
laboratory that was used to conduct experiments in electricity and
magnetism. He subsequently served as the first secretary of the
Smithsonian Institution.
</p>
<p>
Many of the mechanisms and apparatus that Henry developed for his
research and teaching are still preserved in the Joseph Henry
collection at Princeton. Michael Littman, a Professor of Mechanical
and Aerospace Engineering, is the founder of the Joseph Henry
Apparatus project at Princeton, University. This project is focused on
reconstruction of historic electromechanical devices such as early
models of electric motors, solenoids, relays, and related scientific
instruments.

A reconstruction (right) of an early electric motor based on an 1835
sketch by Joseph Henry (left) is an example of a device developed
through this project.
