The Compound Microscope. In 1623 Galileo Galilei mentioned an invention that would still be used to this day. He wanted a telescope that “modified to see objects very close". Before the name the "microscope was made original scientists would call it an "occhialino", a "cannoncino", a "perspicillo", and an "occhiale". The first microscopes of the "Galilean" type had, like the telescope, a concave lens and a convex one mounted in a rigid tube.
