The Collection of Historical Scientific Instruments
at Harvard University
Harvard University has been acquiring scientific instruments on a continuous basis for teaching and research since 1672. The Collection of Historical Scientific Instruments, which was established in 1948 to preserve this apparatus as a resource for teaching and research in the history of science and technology, has become one of the three largest university collections of its kind in the world. Originally associated with the Harvard library system, the Collection was placed under the stewardship of the Department of History of Science in 1987.
