The story of the first "compound" (more than 1 lens) microscope is an interesting one. Much is unknown, yet many things are known.
• Credit for the first microscope is usually given to Zacharias Jansen, in Middleburg, Holland, around the year 1595. Since Zacharias was very young at that time, it's possible that his father Hans made the first one, but young Zach took over the production.
• Details about these first Jansen microscopes are not clear, but there is some evidence which allows us to make some good guesses about them.
• The above early microscope found in Middleburg, Holland, corresponds to our expectations of the Jansen microscopes.
