Charles Babbage
• The analytical engine
• First described in 1837
• Worked on until his death in 1871
• Never really built
• Mechanical
• Essentially a “modern design” in that it used algorithms

Herman Hollerith
• Statistical tabulator• Electrical device for completing
calculations• 1889• Hollerith combined his company with three
others to form a company called the Computing Tabulating Recording Company
• Became IBM

• Electronic Numerator Integrator and Comparator
• Electronic computer using vacuum tubes
• Designed to calculate artillery trajectories
• 1946

ALTAIR 8800
• Introduced in 1975
• A kit computer designed to be assembled by hobbyists
• Used BASIC computer language
• ALTAIR BASIC was designed by Bill Gates and included with the machine

MICROSOFT
• Gates left Harvard to found Microsoft based on the success of BASIC
• Personal Computer Disk Operating System (PC-DOS) brought real success to Microsoft
• DOS allowed average users to operate the computer without knowing programming language

APPLE
• Steve Jobs, Steve Wozniak and Ronald Wayne
• Founded in 1976
