John Wrench was born in Westfield, New York back in 1911 however, he grew up in Hamburg, New York. In 1933, he received a BA summa cum laude I mathematics and a MA in 1935. In 1938, he got his PhD in mathematics from Yale University.
He started out his career teaching at George Washington University however, he joined the United States Navy during WWII developing high-speed computational methods. Working on projects such as underwater sound waves, underwater explosions, structural design, hydrodynamics and aerodynamics to name a few.
His focus was however, was to compute the decimal digits of π(pi). In 1960, using an IBM 7090 he ran the formula out to an astronomical 100,000 digits. He printed out the results, had it bound and the printout can be found at the Smithsonian Institute. He published over 150 scientific papers on math. One last thing is also calculated many other mathematical constants to a high precision. Until tomorrow keep a smile on your face and a penny in your pocket
