Aiken studied at the University of Wisconsin–Madison and later obtained his PhD in physics at Harvard University in 1939. During this time, he encountered differential equations that he could only solve numerically. He envisioned an electro-mechanical computing device that could do much of the tedious work for him. This computer was originally called the ASCC (Automatic Sequence Controlled Calculator) and later renamed Harvard Mark I. With engineering, construction, and funding from IBM, the machine was completed and installed at Harvard in February, 1944. Grace Hopper joined the project in July of that year. In 1947, Aiken completed his work on the Harvard Mark II computer. He continued his work on the Mark III and the Harvard Mark IV. The Mark III used some electronic components and the Mark IV was all-electronic. The Mark III and Mark IV used magnetic drum memory and the Mark IV also had magnetic core memory.
Aiken accumulated honorary degrees at the University of Wisconsin, Wayne State and Technische Hochschule, Darmstadt. He was elected a Fellow of the American Academy of Arts and Sciences in 1947. He received the University of Wisconsin–Madison College of Engineering Engineers Day Award in 1958, the Harry H. Goode Memorial Award in 1964, the John Price Wetherill Medal in 1964, and IEEE's Edison Medal 'For a meritorious career of pioneering contributions to the development and application of large-scale digital computers and important contributions to education in the digital computer field.' in 1970.
In addition to his work on the Mark series, another important contribution of Aiken's was the introduction of a master's program for computer science at Harvard, nearly a decade before the programs began to appear in other universities. This became a starting ground to future computer scientists, many of whom did doctoral dissertations under Aiken.
Personal life 
Howard Aiken was married three times. First to Lousie Mancill, second to Agnes Montgomery, third to Mary McFarland. He had two children; Rachel Ann by his first wife, Elizabeth (Betsy) by his second.
Howard Aiken was also an Officer in the United States Navy Reserve.
After he retired at age 60 to Fort Lauderdale, Florida, Aiken continued his contributions to technology. He founded Howard Aiken Industries Incorporated, which was a consulting firm that helped failing businesses recover. During his years in Florida, he joined the University of Miami as a Distinguished Professor of Information. In addition, Aiken became a consultant for companies such as Lockheed Martin and Monsanto. On March 14, 1973, Aiken died during a consulting trip to St. Louis, Missouri .
