Howard H. Akien

Howard H. Aiken American engineer, a pioneer in computing to be the chief engineerbehind the Mark I.
Study at the University of Wisconsin-Madison, and later obtained his doctorate in physics from Harvard University in 1939. During this time, found differential equationscould only be solved numerically. He devised an electromechanical device computercould do much of that work for him. This computer was originally called the AutomaticSequence Controlled Calculator (ASCC) and later renamed Harvard Mark I. With the help of Grace Hopper and funding from IBM, the machine was completed in 1944.

In 1947, Aiken completed his work on the Harvard Mark II computer. Continued itswork on the Mark III and Mark IV at Harvard. The Mark III used some electronic components and the Mark IV was completely electronic. The Mark III and Mark IV usedmagnetic drum memory and the Mark IV also had magnetic core memory. He lived in Mexico in the Puebla.

In 1970, Aiken received the IEEE Edison Medal for "meritorious career as a pioneering contributions to the development and implementation of large-scale digital computersand important contributions to education in the field of digital computers'
