Connaught Laboratories: A Brief History.

Known as Connaught Laboratories during most of the 1920s through 1940s, and as Connaught Medical Research Laboratories after 1946, the Labs remained an uniquely organized, non-commercial and self-sustaining part of the University of Toronto from 1914 until 1972, when it was sold to the Canadian Development Corporation (CDC), a federal Crown corporation, and privatized. By 1989 the CDC had divested much of its interest in Connaught and Institut Merieux of Lyon, France, acquired a controlling stake in the company. By this time, Institut Mérieux had formed an alliance with the Pasteur Institute. Over the next decade Connaught remained the Canadian component of what became known as Pasteur Merieux Connaught, which, in turn, was owned by Rhone Poulenc, a French multinational chemical, agricultural and biotech company.  In December 1999, Rhône Poulenc and the German pharmaceutical and chemical company, Hoechst, joined forces to create a new pharmaceutical/ biotech giant known as Aventis. In the process, Connaught's identity changed in a significant way for the third time since 1972. Pasteur Mérieux Connaught became known as Aventis Pasteur, and in Canada became the "Connaught Campus" of Aventis Pasteur. However, within five years, Aventis was transformed into the even larger Sanofi-Aventis Group, following the acquisition of Aventis by Sanofi-Synthelabo of Paris. The original Connaught identity thus shifted yet again to become the Canadian component of Sanofi Pasteur, the global vaccine business of Sanofi-Aventis.
