Who was the first inventor of nanotechnology?

The concept of Nanotechnology is often attributed to physicist Richard Feynman, who introduced the idea in his 1959 lecture "There's Plenty of Room at the Bottom." However, the term "nanotechnology" was coined later, in 1974, by the Japanese researcher Norio Taniguchi. While Feynman's work laid the foundational ideas, Taniguchi is recognized for formally defining the field. Thus, both played pivotal roles in the development of nanotechnology.
