A History of Computers Charles Babbage is credited as the father of computer. Although never actually built, he proposed the computing machines called Difference Engine and Analytical Engine that possessed the core characteristics of today’s computers. Ada Lovelace, who wrote demonstration programs for Analytical Engine, is credited as the first programmer. The first modern computer was built by Atanasoff of Iowa State University in the late 1930s. An electromechanical computer MARK I was built by Howard Aiken of Harvard. The first completely electronic computer ENIAC I was built by Mauchly and Eckert of the University of Pennsylvania. 4th Ed Chapter 0 - ©The McGraw-Hill Companies, Inc.

In 1823 he received a grant from the British government to build a mechanical device he called the Difference Engine. The machine was not completed. Babbage worked on even more ambitious machine he called Analytical Engine. One unique feature of Analytical Engine is its programmability. Although the Analytical Engine was never built, its demonstration program was written by Ada Lovelace, a daughter of the poet Lord Byron. In the late 1930s John Atanasoff of Iowa State University, with his graduate student . | Chapter 0 Introduction to Computers and Programming Languages 4th Ed Chapter 0 - ©The McGraw-Hill Companies, Inc.
