When giving credit, get it right

Mitch Kapor, in Jim Fallow’s blog, has weighed in on who did what back in the early days of spreadsheets.  While I gave him credit for being the first to adapt the spreadsheet to the IBM PC, Mitch points out that both VisiCalc and MultiPlan (Microsoft’s first spreadsheet product) were available for the IBM PC before 1-2-3 shipped in January 1983.  He’s right of course and I should have remembered that. Thanks to Jim for straightening that out.

Dan Bricklin and  Bob Frankston’s distinction stands:  they invented VisiCalc, the original spreadsheet product for personal computers and one hell of a killer app.
