who created the compound microscope
Optical microscope invention and the first microscopes. It is widely believed that Dutch spectacle makers, Zacharias Jansen and his father Hans were responsible for making the first compound microscope in the late 16th century (Z Janssen c. 1580 - 1638). The microscope consisted of three draw tubes with lenses inserted into the ends of the flanking tubes. The eyepiece lens was bi-convex and the objective lens was plano-convex, a very advanced compound design for this time period.
