Nikola Tesla's alleged obsession with the number three is often cited but lacks substantial evidence in his autobiographies and biographies. Some sources suggest he exhibited obsessive-compulsive behaviors, such as needing to walk around a block three times, but these claims are not consistently referenced. A popular quote attributed to Tesla about the significance of the numbers 3, 6, and 9 remains unverified, adding to the ambiguity surrounding his beliefs. Discussions also highlight that while Tesla's eccentricities contribute to his fame, many other inventors have made significant contributions without the same level of notoriety. The fascination with Tesla often intertwines with myths and interpretations that may not accurately reflect his true views or experiences.
