Nikola Tesla (1856-1943)
As a young apprentice in Thomas Edison’s New York office, Tesla regularly worked from 10:30 in the morning until 5:00 the following morning. (“I’ve had many hardworking assistants, but you take the cake,” Edison told him.) Later, after he had started his own company, Tesla arrived at the office at noon. Immediately, his secretary would draw the blinds; Tesla worked best in the dark and would raise the blinds again only in the event of a lightning storm, which he liked to watch flashing above the cityscape from his black mohair sofa. He typically worked at the office until midnight, with a break at 8:00 for dinner in the Palm Room of the Waldorf-Astoria hotel.
These dinners were carefully scripted affairs. Tesla ate alone, and phoned in his instructions for the meal in advance. Upon arriving, he was shown to his regular table, where eighteen clean linen napkins would be stacked at his place. As he waited for his meal, he would polish the already gleaming silver and crystal with these squares of linen, gradually amassing a heap of discarded napkins on the table. And when his dishes arrived–served to him not by a waiter but by the maitre d’hotel himself–Tesla would mentally calculate their cubic contents before eating, a strange compulsion he had developed in his childhood and without which he could never enjoy his food.
