The first compound microscope was made in 1590 in The Netherlands. Hans Lippershey, Sacharias Jansen, and Hans Jenssen, all eyeglass makers, have each been given credit for the invention. Apparently working independently but at the same time, they developed almost identical concepts. See the related link for more information.
If a microscope is any instrument that allows the inspection of objects that the unaided eye can't see, then reading stones were the first microscopes, Egypt, ca 7,000+ BC .These were probably very similar to what Leeuwenhoek found being used by cloth merchants (ca. 1648) to count the threads in cloth. The next candidate would be spectacles. There is little controversy over the date: ca. 1285 CE. There is more contention concerning the inventor, but Salvino D'Armate is most often credited with the first wearable eyeglasses.
If the definition of microscope requires the use of an instrument, in or upon which, to mount the lenses, then eyeglasses fit this definition too. If multiple lenses are the criteria, then the compound microscope, mentioned above, is the choice.
Antonie Philips van Leeuwenhoek (ca. 1668) and Galileo Galilei (ca. 1624), are sometimes credited with the invention of the microscope, but they were actually the authors of its improvement, not its inventors. Interestingly, it was a friend of Galileo's, Johannes Faber, that gave the name, microscope, to Galileo's instrument. (So, in this left-handed way, perhaps Galileo actually did 'invent' the microscope
