Zacharias Janssen

Zacharias Janssen was a Dutch optician and inventor from the late 16th and early 17th centuries, credited with creating one of the earliest optical devices resembling a microscope. While not definitively proven, he is believed to have developed a simple magnifying instrument by stacking multiple lenses in a tube, which could enlarge tiny objects. This invention laid the groundwork for the development of microscopes, revolutionizing science by allowing humans to see and study microscopic structures. Janssen’s work contributed significantly to optics and scientific discovery, marking a key moment in the history of microscopy and scientific exploration.
