Detroit Institute of Arts

Richard Manoogian, who led Michigan building-products maker Masco for decades and was a major benefactor of the Detroit Institute of Arts, has died at the age of 90. He transformed the company into a global supplier of faucets, cabinets and other home fixtures, and his philanthropy left a lasting mark on Detroit's cultural institutions. The business and arts communities are mourning a figure regarded as one of the region's most influential executives and patrons.
