The RAND Corporation’s JOHNNIAC runs-1954

 

The JOHNNIAC computer is one of 17 computers that followed the basic design of Princeton's INstitute of Advanced Study (IAS) computer. It was named after John von Neumann, a world famous mathematician and computer pioneer of the day. Completed in 1954, JOHNNIAC was used for scientific and engineering calculations. It was also repeatedly expanded and improved throughout its 13-year lifespan. Many innovative programs were created for JOHNNIAC, including the time-sharing system JOSS that allowed many users to simultaneously access the machine.
