William Shanks (25 January 1812 – June 1882)[1] was an English amateur mathematician. He is famous for his calculation of π to 707 places in 1873, which was correct up to the first 527 places.[2] The error was discovered in 1944 by D. F. Ferguson (using a mechanical desk calculator).[2] Nevertheless, Shanks's approximation was the longest expansion of π until the advent of the digital electronic computer in the 1940s.
