Charles Babbage, an English mathematician and inventor, is widely recognized as the father of the computer for his work on the Analytical Engine, a mechanical general-purpose computer.

ENIAC (Electronic Numerical Integrator and Computer) was the first electronic computer, developed by John Atanasoff and Clifford Berry at the University of Pennsylvania.

John von Neumann, a Hungarian-American mathematician and physicist, is often referred to as the 'father of the modern computer' for his contributions to computer architecture and the development of the stored-program concept.

Grace Hopper, an American computer scientist and US Navy rear admiral, was the lead developer of COBOL (Common Business-Oriented Language), a widely used programming language designed for business applications.

The Apple I, designed and hand-built by Steve Jobs and Steve Wozniak, is considered to be the first personal computer.

Xerox PARC (Palo Alto Research Center) developed the first graphical user interface (GUI) in the early 1970s, which later influenced the development of GUIs in popular operating systems like Apple's macOS and Microsoft Windows.
