Emma Walmsley

The London-based pharma exec runs the world’s leading over-the-counter pharma company—a $9.5 billion joint venture between GSK and its Swiss competitor Novartis, officially launched in March. Walmsley led the integration of the businesses, which resulted from a complex deal struck in April 2014. The company’s products are sold in 160 countries, with 42% of sales coming from emerging markets. In July, Walmsley, a lover of Italian red wine and Bikram yoga, was appointed to the board of Diageo. —Erika Fry
