Hooke's microscope and equipment. 17th-century illustration of a compound microscope (bottom, see image H505/0008), as used by English natural philosopher Robert Hooke (1635-1703). Hooke pioneered the new science of microscopy and published detailed drawings of observations made with his microscopes. This illustration appeared in his 'Micrographia' (1665). A lens polishing machine is at upper right (see image H505/0030) and a wheel barometer is at upper left (see image V900/0017). Hooke was one of the founding fellows (1663) of the Royal Society, and served as its Curator of Experiments and Secretary.
