India mourned the demise on Sept. 9 of Dr. Verghese Kurien, whose pioneering work at the intersection of dairy-farming technology, the cooperative sector, and branding and marketing created one of the nation’s greatest business success stories. Kurien, who died at 90, was a revolutionary in the dairy sector, and the brand that he created, Amul, today enjoys more name recognition and goodwill than almost any other.
