Which inventor is often credited with the quote 'Genius is one percent inspiration and ninety-nine percent perspiration'?

• A. Nikola Tesla
• B. Thomas Edison
• C. Albert Einstein
• D. Benjamin Franklin

Answer: (B)

Thomas Edison is the figure most closely associated with that line. The idea being tested is that invention relies as much on persistent effort as on bright ideas. Edison built a vast research lab and spent countless hours testing, refining, and rejecting ideas until something worked. That relentless, iterative process is what the quote aims to capture: inspiration may start a project, but ongoing hard work, experiments, and perseverance drive real breakthroughs. While the exact wording isn’t verifiably from a single source, it aligns with Edison’s celebrated approach to invention. The other names are linked to different quotes or notions about genius, imagination, or invention, so they don’t fit this particular saying as clearly.
