Most prolific inventors of all time

As famously stated in Plato's Republic: "Necessity is the mother of invention." This 'necessity' to which he is speaking manifests itself in our lives in varying degrees of regularity. For many of us, our day-to-day needs and desires have been experienced so many thousands of times that innumerable individuals throughout history have thought up unique methods of addressing them. However, as we become more deeply entrenched in the technologically-driven age, new problems arise every single day, each one demanding a creative, meticulously-designed solution.

Thomas Edison's name has become so culturally synonymous with the concept of invention that it may surprise you to learn that he is not the most prolific inventor of all time; as it turns out, he just barely cracks the top ten. Instead, the Father of Invention has been superseded by a cohort of contemporary mega-minds in fields ranging from microbiology to computer systems and information technology.

Stacker referenced data from the United States Patent and Trademark Office in order to compose a list of the 25 most prolific inventors ever, sorted according to the number of registered U.S. utility patents held. As our world becomes ever more digitized and new innovative opportunities perpetually arise, this list is subject to change in the future.
