Susan L. Wagner, founding partner and director of BlackRock, has been elected to Apple’s board of directors. Bill Campbell, the board’s longest-serving member, is retiring after 17 years. Wagner co-founded BlackRock in 1988 and helped it become one of the world’s most successful asset-management companies. “Sue is a pioneer in the financial industry and we are excited to welcome her to Apple’s board of directors,” said Tim Cook, Apple’s CEO. “We believe her strong experience, especially in M&A and building a global business across both developed and emerging markets, will be extremely valuable as Apple continues to grow around the world.” Wagner has been recognized as one of Fortune Magazine’s 50 Most Powerful Women in Business and honored by the National Council for Research on Women. “I have always admired Apple for its innovative products and dynamic leadership team, and I’m honored to be joining their board,” Wagner said.
