Micrographia: or Some physiological descriptions of minute bodies made by magnifying glasses; with observations and inquiries thereupon. London, Printed for Ho. Martyn and Ja. Allestry, printers to the Royal Society, 1665.
Hooke, at one time research assistant to Robert Boyle, was one of the greatest inventive geniuses of all time. He constructed one of the most famous of the early compound microscopes. His Micrographia is the earliest work devoted entirely to an account of microscopical observations and is probably the most influential book on the subject in English. Containing 38 copperplate engravings mostly after drawings by Hooke, with some probably after drawings by the architect and occasional scientist, Sir Christopher Wren. Micrographia is one of the most dramatically illustrated books of the 17th century. Among its many innovations, it includes the coinage of the modern biological usage of the word "cell" to describe the microscopic structure of tissue.
