Illustration from Robert Hooke's 'Micrographia'. Hooke (1635-1703) studied at Oxford University, and whilst he was there he met Robert Boyle, and assisted him in the construction of an air pump. In 1660 he moved to London and became one of the founder members of the Royal Society, at which he held the post of 'Curator of Experiments'. 'Micrographia', the first important work on microscopy, was published in 1664 and contains illustrations of some of the specimens Hooke viewed under the compound microscope that he designed, as well as the microscope itself. Specimens were illuminated by focussing the light reflected off an oil-filled glass globe onto the base of the instrument.
