Ellen Kullman

Title: Chairman and CEO
Company: DuPont
Country: USA

Kullman’s reinvention of DuPont has a distinctly international flavor to it: Her 2011 acquisition of Danish food enzyme maker Danisco was key to an effort to push the company deeper into agriculture and nutrition (along with biotech and advanced materials). A third of the company’s sales, $15.5 billion in the past six months, come from developing markets.
