VisiCalc publicly demonstrated for the first time
11th May 1979
Dan Bricklin came up with the idea of a computerised spreadsheet program while preparing a report for his Harvard Business School course. He wanted to create a program where people could visualize a spreadsheet as they created it.
During 1978, Bricklin together with colleagues Bob Frankston and Daniel Fylstra created the software to realise his vision. They called their program VisiCalc, short for "visible calculator". VisiCalc was the first computerized spreadsheet program.
On 11th May 1979 Bricklin and Frankston give the first public demonstration of VisiCalc at the 4th West Coast Computer Faire, held in San Francisco.
