Apple just announced that longtime board member and former VP of Marketing Bill Campbell is leaving the company as founding partner and director of BlackRoc Susan L. Wagner joins the company’s board of directors. Apple CEO Tim Cook noted in the company’s press release today that he thinks Apple will benefit from Wagner’s experience with “M&A and building a global business across both developed and emerging markets.”

“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.”

Apple chairman Art Levinson said the company “conducted an exhaustive search for someone who would further strengthen our board” before deciding on Wagner. “I’m confident that Sue is going to make an important and positive impact on our company.”

Earlier this month a report from The Wall Street Journal noted Tim Cook was actively looking to add new board members as six of the company’s seven are now aged 63 or older.

Campbell leaves the company to retire after 17 years and serving as a board member (the longest serving at the company ever) since Steve Jobs returned in 1997. Apple notes in its press release below that Campbell first joined the company in 1983 as the Vice President of Marketing:

He not only helped Apple survive, but he’s led us to a level of success that was simply unimaginable back in 1997.”
