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 todays computers Ada lovelace, who wrote demonstration programs for analytica 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 C 2000 McGraw-Hill Introduction to Object-Oriented Programming with Java--Wu Chapter 0-3
