Truman Henry Safford (1836 – 1901) was an American calculating prodigy. In later life he was an observatory director.
At an early age he attracted public attention by his remarkable calculation powers. At the age of nine, a local priest asked him to multiply 365,365,365,365,365,365 by itself. In less than a minute, Truman gave the correct answer of 133,491,850,208,566,925,01
At around this age he also developed a new rule for calculating the moon's risings and settings, taking one-quarter of the time of the existing method.
