Key moments in Genzyme's history
2011 - Sanofi makes transition into Genzyme
Two months after the completed deal, Sanofi unveils a new research facility called the Sanofi Boston R&D Hub, which will help to coordinate existing research operations in Massachusetts. Genzyme discovery programs will operate within that unit as the Genzyme R&D Center.
As of this announcement, Sanofi had about 5,000 employees in the Boston area, including 4,500 at Genzyme corporate, research, and manufacturing sites.
