In 1977 Samuel J. Corso joined the studio and became a partner. In 1990 the name was changed to Dufour/Corso Studios, Ltd. and in 1992, Paul retired and Sam became President. Over the course of the years the studio has diversified and now includes the design and fabrication of projects in bronze sculpture, mosaics, tapestries and furniture design.
Dufour/Corso was founded in 1964 by Paul A. Dufour and was incorporated under the name Dufour Glass Studio, Ltd. The main emphasis at that time was commissioned, leaded stained glass and the development of independent glass panels for exhibition purposes.
