Historical Scientific Instruments continues to teach and amaze

Since 1672, Harvard University has been acquiring scientific instruments for teaching and research. In 1948, the Collection of Historical Scientific Instruments was established to preserve the objects as a resource for teaching and research in the history of science and technology. It has since grown to more than 20,000 objects making it 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. Whether it’s the handmade globe electrical machine (circa 1750) Harvard President Edward Holyoke created using recycled materials to perform experiments with Professor John Winthrop or the camera obscura given to the College by Benjamin Franklin, these astonishing collections never cease to amaze.
Within their stately pyramidal cases, these Culpeper-type microscopes made in London (circa 1730) focus using a mechanism that is similar to early telescopes with draw tubes.
These 17th-century sand glasses measure time in 30- and 60-minute increments.
A drawer full of microscope slides contain animal tissue, plants, and insects along with a binocular microscope made by H. & W. Crouch, London, 1862‒1867. This thick glass tube is a treasured relic of the great English chemist Joseph Priestley, who invented carbonated water in 1767 and discovered oxygen in 1774. Despite his scientific fame, Priestley was forced to emigrate to the U.S. in 1794 because of his radical political and religious views. His contemporary, chemist Robert Hare of the University of Pennsylvania, gave it to Harvard. Harvard President Edward Holyoke used recycled materials to assemble this globe electrical machine (circa 1750). Parts include an egg cup, broken goblet, and cookie press. He performed experiments with Professor John Winthrop.
Benjamin Franklin selected this huge, book-shaped camera obscura (left) for Harvard College in 1765. It was among apparatus shipped from London to replace items lost in the Harvard Hall fire of 1764. This mahogany octant with an ivory scale and its original keystone case was made by John Bleuler, London (circa 1775‒1790), and later repaired in Salem, Mass., by Gedney King. After being used during nautical explorations, the instrument was used to teach Harvard College students the principles of navigation. In 1953, it was transferred to the collection from the Students’ Astronomical Laboratory.
This Nobel Prize medal was awarded in 1965 to Harvard physicist Julian Schwinger, who shared the prize with Richard Feynman and Sin-Itiro Tomonaga “for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles.” Harvard students learned mechanics from this wooden model of interlocking gears deployed in mills. It was made in London by Watkins & Hill between 1830 and 1850.
