It's not clear who first invented microscopes, but they emerged around the 1590s with few of the bells and whistles they have today.
Two different sources are credited with the invention of the microscope: Hans Lippershey, who filed the first patent for a telescope in 1608, and Hans and Zacharias Janssen, a father-son team who wrote about microscopes in the 1590s.

#10 An old choir director of mine lived next door to one of the guys who developed the earliest patents for home microwave ovens. They were approved and being marketed by the 70s, but he wouldn't have one in his house until the 90s because they still leaked too much radiation of some sort.

Edison gets way too much credit as usual. He didn't invent the light bulb he perfected it. What took him so long was that he didn't read through any of the work of previous scientists instead making their same mistakes over and over. I believe it was after Eastman came along that he got things organized and started making some actual progress.
