Dutch maker of spectacles who invented the first compound microscope in 1590 (a compound microscope is one which has more than one lens). The lens in the eyepiece was bi-convex (bulging outwards on both sides), and the lens of the far end (the objective lens) was plano-convex (flat on one side and bulging outwards on the other side). This advanced microscope had a 3 to 9 times power of magnification. In 1608 he made the first telescope together with Hans Lippershey.
