Description
In November 1944, R.S. Whipple’s donation to the University of Cambridge was put on show in the East Rooms of the Old Schools. The University accepted the donation on the condition that they found a new institution within which to house the collection.

Whipple himself wrote a guidebook to this exhibition, describing some of the more important objects and books on show. The front cover includes the following declaration: “The Exhibits are drawn from the Collection which Mr R.S. Whipple is presenting to the University and will form a nucleus for a History of Science Museum and Library in Cambridge.”

Whipple’s own explanatory text for this object is:

"Armillary sphere. On brass stand, 8 1/2 in. diam. Marked "Fenig fecit". The sphere is supported by a figure of Atlas. c. 1700."
