About Duet Software, Inc.

Peter Findlay retired in June 2013 after thirty-three years teaching at Wolfe and Mackenzie Schools in Vancouver. Doug Colpitts retired in June 2008 after thirty-three years at Norquay School. They began writing software for their own students in the early 1990's, first on the Amiga platform and then for Windows and MacOS. In 1997, they created the first version of Silhouette which expanded to Silhouette 4, SilhouetteCE, SilhouetteELAR, SilhouetteIEP, SilhouetteGlenbrook, SilhouetteQMS, SilhouetteNW and SilhouetteDelta. SilhouetteDelta subsequently morphed into CSLDelta. As of fall 2020, only SilhouetteELAR4 and CSLDelta are supported.
