Who had the greater influence on the twentieth century?

Most of his scientific work had little influence on events of the twentieth century.

Of the 100 chosen, Albert Einstein was chosen as the Person of the Century, on the grounds that he was the preeminent scientist in a century dominated by science. The editors of Time believed the 20th century "will be remembered foremost for its science and technology", and Einstein "serves as a symbol of all the scientists—such as Heisenberg, Bohr, Richard Feynman, ...who built upon his work".[1]

By the end of his brilliant and tortured life, the Serbian physicist, engineer and inventor Nikola Tesla was penniless and living in a small New York City hotel room. He spent days in a park surrounded by the creatures that mattered most to him—pigeons—and his sleepless nights working over mathematical equations and scientific problems in his head. That habit would confound scientists and scholars for decades after he died, in 1943. His inventions were designed and perfected in his imagination.

I'm certainly not anti-Serb, but if the dude was so important then why
