Borland

Borland Software Corporation was a computer technology company founded in 1983 by Niels Jensen, Ole Henriksen, Mogens Glad and Philippe Kahn. Its main business was the development and sale of software development and software deployment products... Borland developed a series of software development tools. Its first product was Turbo Pascal in 1983, developed by Anders Hejlsberg (who later developed .NET and C# for Microsoft)... 1984 saw the launch of Borland Sidekick, a time organization, notebook, and calculator utility that was an early terminate-and-stay-resident program (TSR) for DOS operating systems... In 1985 Borland acquired Analytica and its Reflex database product. The engineering team of Analytica, managed by Brad Silverberg and including Reflex co-founder Adam Bosworth, became the core of Borland's engineering team in the USA. Brad Silverberg was VP of engineering until he left in early 1990 to head up the Personal Systems division at Microsoft. Adam Bosworth initiated and headed up the Quattro project until moving to Microsoft later in 1990 to take over the project which eventually became MS-Access... In September 1987 Borland purchased Ansa-Software, including their Paradox (version 2.0) database management tool. Richard Schwartz, a cofounder of Ansa, became Borland's CTO and Ben Rosen joined the Borland board. The Quattro Pro spreadsheet was launched in 1989 with, at the time, an improvement and charting capabilities... In September 1991 Borland purchased Ashton-Tate, bringing the dBASE and InterBase databases to the house, in an all-stock transaction.[10] Competition with Microsoft was fierce. Microsoft launched the competing database Microsoft Access and bought the dBASE clone FoxPro in 1992, undercutting Borland's prices. https://en.wikipedia.org/wiki/Borland
