Nikola Tesla (1856-1943). Serbian-American inventor whose alternating-current electrical system became the global standard for power distribution and whose patents underlie radio, fluorescent lighting, induction motors, the rotating magnetic field, and several technologies attributed to others during his lifetime. Tesla's cognitive signature is exceptionally well-documented and was apparent to everyone who met him: severe sensory sensitivities (he could not bear the touch of human hair, the sight of pearls produced nausea, the sound of dripping water was physically painful), repetitive counting rituals (he calculated the cubic contents of every soup bowl and coffee cup before he would eat), exact dietary regimens that varied across decades, and what his contemporaries called "eccentricities" but which contemporary clinical literature would identify as a cluster of obsessive-compulsive features alongside what reads as a strong autistic profile. He worked alone, mostly at night, for sixteen-hour stretches in absolute silence. His most original work was conducted with no integration partner — Edison was a rival, not a collaborator, and Westinghouse was a backer rather than a translator — and Tesla died in poverty in a New York hotel room despite having produced foundational discoveries that the twentieth century built on. The pattern: discovery specialty operating without sufficient integration support, with the predictable result that credit and material outcomes accrued to the figures who had the integration apparatus to capture them.
