Joseph Marie Jacquard
In France, Joseph Marie Jacquard invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards. -
Charles Babbage
English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. The project, funded by the English government, is a failure. More than a century later, however, the world's first computer was actually built. -
Herman Hollerith
Herman Hollerith designs a punch card system to calculate the 1880 census, accomplishing the task in just three years and saving the government $5 million. He establishes a company that would ultimately become IBM. -
Alan Turing
Alan Turing presents the notion of a universal machine, later called the Turing machine, capable of computing anything that is commutable. The central concept of the modern computer was based on his ideas. -
J.V Atanasoff
J.V. Atanasoff, a professor of physics and mathematics at Iowa State University, attempts to build the first computer without gears, cams, belts or shafts. -
David Packard and Bill Hewlett
Hewlett-Packard is founded by David Packard and Bill Hewlett in a Palo Alto, California, garage, according to the Computer History Museum. -
Clifford Berry
Atanasoff and his graduate student, Clifford Berry, design a computer that can solve 29 equations simultaneously. This marks the first time a computer is able to store information on its main memory. -
John Mauchly and J. Presper Eckert
Two University of Pennsylvania professors, John Mauchly and J. Presper Eckert, build the Electronic Numerical Integrator and Calculator (ENIAC). Considered the grandfather of digital computers, it fills a 20-foot by 40-foot room and has 18,000 vacuum tubes. -
William Shockley, John Bardeen and Walter Brattain
William Shockley, John Bardeen and Walter Brattain of Bell Laboratories invent the transistor. They discovered how to make an electric switch with solid materials and no need for a vacuum. -
Grace Hopper,Thomas Johnson Watson Jr. and Thomas Johnson Watson Sr
Grace Hopper develops the first computer language, which eventually becomes known as COBOL. Thomas Johnson Watson Jr., son of IBM CEO Thomas Johnson Watson Sr., conceives the IBM 701 EDPM to help the United Nations keep tabs on Korea during the war. -
John Backus
The FORTRAN programming language, an acronym for Formula Translation, is developed by a team of programmers at IBM led by John Backus, according to the University of Michigan. -
Jack Kilby and Robert Noyce
Jack Kilby and Robert Noyce unveil the integrated circuit, known as the computer chip. Kilby was awarded the Nobel Prize in Physics in 2000 for his work. -
Douglas Engelbart
Douglas Engelbart shows a prototype of the modern computer, with a mouse and a graphical user interface (GUI). This marks the evolution of the computer from a specialized machine for scientists and mathematicians to technology that is more accessible to the general public. -
Alan Shugart
Alan Shugart leads a team of IBM engineers who invent the "floppy disk," allowing data to be shared among computers. -
Robert Metcalfe
Robert Metcalfe, a member of the research staff for Xerox, develops Ethernet for connecting multiple computers and other hardware.
