"Incidently, π is now know, by computation in the ENIAC computer at Aberdeen Proving Ground, to 2035 digits; the result of the voluntary week-end work of four operators of the machine!"

— Raymond L. Wilder, Introduction to the Foundations of Mathematics (Wiley, 1952), p. 235

(According to the Wikipedia entry on π, it was 2037 digits, the year was 1949, 70 hours were required, and John von Neumann was in charge.)
