Bartik converted the ENIAC into a stored program computer by March 1948. As head of this process, Bartik was charged with the conversion that allowed the ENIAC to be turned into rudimentary stored program computer to assist with Clippinger's wind tunnel programs, which allowed the ENIAC to operate more quickly, efficiently, and accurately. Letters between Bartik and Adele Goldstine were discovered by authors Thomas Haigh and Mark Priestley during the time of the project, as well as, the fact that much of the 60-order Code was in Bartik's handwriting.
