The History of Harvard Mark 1: A Complete Guide

The Harvard Mark 1 was the first computer that could be programmed to solve any number of problems, rather than built to solve one specific thing.

Howard Aiken (see the biography of Howard Aiken) initially designed the Mark 1 in 1937 while still a graduate student at Harvard.

When was the Harvard Mark 1 invented?

It used punched tape and a series of switches and drive shafts to automatically perform calculations and was also known as the IBM Automatic Sequence Controlled Calculator.

What is the Harvard Mark 1?

The Mark 1 was programmed using punched tape and punched cards, a typical method of programming early computers.

How was the Harvard Mark 1 programmed?

It could calculate 3 sets of addition or subtraction per second. Multiplication and division took longer, while more complicated functions required more than a minute.
