American mathematician working mainly in numerical analysis.
Pioneer of the use of computers for mathematical calculations
Best known now for his work with Daniel Shanks to calculate $\pi$ to $100 \, 000$ decimal places.

- In order to assure the preservation of this document, I arranged for two clear copies of the output to be printed and specially bound (inscribed in gold letters) -- one of which I donated to the Smithsonian Institution in Washington, D.C.; the other I kept. The transfer to the Smithsonian took place at a small ceremony, attended by about 25 invited guests.
