Posts claim these were inventor Nikola Tesla's last words: "All these years that I had spent in the service of mankind brought me nothing but insults and humiliation." But there's no evidence that's true.

Snopes.com investigated claims that a post on social media showed Nikola Tesla's last words before his death in 1943. The posts claimed Tesla's final message to his mother was that his years of serving mankind brought him 'nothing but insults and humiliation.' However, no evidence supports the authenticity of Tesla's alleged last words. The claim originated from a letter that Tesla allegedly wrote to his mother, but the quote did not appear online before 2015. A Serbian fact-checking organization concluded that the letter was not authentic due to numerous illogicalities and inconsistencies.
