Drawing of cork seen under a microscope; the first picture showing "cells" in a biological specimen, named as such by Robert Hooke. He prepared the specimen by making thin slices with a razor blade, and thus he invented the technique of sectioning; the discovery was described to the Royal Society of London on 13th April 1663. This figure first appeared in his book called "Micrographia"; this contains some of the most beautiful drawings of microscope observations ever made.
