The Whipple Museum's collection includes scientific instruments, apparatus, models, pictures, prints, photographs, books and other material related to the history of science. The museum's holdings are particularly strong in material dating from the seventeenth to the nineteenth centuries, especially objects produced by English instrument makers, although the collection contains objects dating from the medieval period to the present day. Instruments of astronomy, navigation, surveying, drawing and calculating are well represented, as are sundials, mathematical instruments and early electrical apparatus. The Whipple Museum was founded in 1944 when Robert Stewart Whipple presented his collection of scientific instruments to the University of Cambridge. Since Robert Whipple's initial gift of the collection, the Museum has come to house many instruments formerly used in the Colleges and Departments of the University of Cambridge.
