History of Microsoft Excel

History of Microsoft Excel
The first spreadsheet on a personal computer was called VisiCalc (short for visible calculator) and was created by Daniel Bricklin and Bob Frankston in 1978. Bricklin, a Harvard Business School student, was looking for an easier way to conduct a case study. He envisioned “an electronic blackboard and electronic chalk in a classroom”. He recruited Frankston to help him write the code. VisiCalc was an instant success and was one of the first “killer apps”.

By early 1980s, Lotus 1-2-3 was the leading spreadsheet. Lotus had bought and then discontinued VisiCalc. Borland’s Quattro Pro was another well-known product at that time.

In 1985, Microsoft Corporation came up with Excel for the Macintosh computer. This product was remarkable for its use pull down-menus and a point and click device called a mouse. Other spreadsheets use a command line interface that required knowledge of cryptic DOS command.

When Microsoft named its spreadsheet software “Excel,” it apparently did not now that Manufacturers Hanover Trust already had an automated banking program called Excel. As part of the settlement for trademark infringement, Microsoft agreed to refer always to its product as Microsoft Excel.
