Passage: Development on Wordfast version 1 (then called simply Wordfast) was begun in 1999 in Paris, France, by Yves Champollion.  It was made up of a set of macros that ran inside of Microsoft Word, version 97 or higher.  At that time, other translation memory programs also worked inside Microsoft Word, for example Trados.
