123 Fulton Street. Here Ian Frazier’s typewriter repairman worked during the Second World War fixing typewriters for the US Government. A letter misplaced on a typewriter in a workshop in lower Manhattan can have implications far away:

“The implications of the work and its difficulty brought him to near collapse, but he completed it with only one mistake: on the Burmese typewriter he put a letter on upside down. Years later, after he had discovered his error, he told the language professor he had worked with that he would fix that letter on the professor’s Burmese typewriter. The professor said not to bother; in the intervening years, as a result of typewriters copied from Martin’s original, that upside-down letter had been accepted in Burma as proper typewriter style.”
