Achievements: Before Microsoft Excel, there was VisiCalc -- the world's first electronic spreadsheet -- and Dan Bricklin was the man behind it. While not widely known as the Father of the spreadsheet, due to the enormous success of Mitch Kapor's Lotus 1-2-3, Bricklin opened up the PC business software market by co-creating a product that helped businesspeople see the necessity of owning a personal computer. Co-founder and chairman of Software Arts, Bricklin introduced his Visible Calculator in October 1979 and changed the way people thought of computers. In 1995, Bricklin founded Trellix, producing products for website creation and publishing, among other things.
Today: Trellix was bought by Interland in 2003, where Bricklin served as CTO until he returned to Software Gardens in 2004. According to his website, he is also a "founding trustee of the Massachusetts Software Council (now the Massachusetts Technology Leadership Council) and has served on the boards of the Software Publishers Association and the Boston Computer Society."
