John Mauchly
and Presper Eckert
In 1945, Mauchly and Eckert built the ENIAC (Electronic Numerical Integrator and Computer).
The ENIAC was built with 18,000 vacuum tubes that failed on an average of once every seven minutes.
After the war, they created the Univac I - the first general-purpose commercial computer.
