Beginnings and the "Tale of VisiCalc"
In 1961, Professor Richard Mattessich pioneered the development of computerized speadsheets for use in business accounting. Some historical information on the computerization of accounting spread sheets using mainframe computers is discussed on Mattessich's web page "Spreadsheet: Its First Computerization (1961-1964)". Rene Pardo and Remy Landau co-invented "LANPAR" LANguage for Programming Arrays at Random in 1969. This electronic spreadsheet type application was used for budgeting at Bell...
