JOIN USLevinson, 61, fills the vacancy left open when co-founder Steve Jobs died last month at age 56 after a long battle with pancreatic cancer. Jobs had been chairman for less than two months, a position created when he stepped down as chief executive in August.
Robert Iger, president and CEO of The Walt Disney Co, was tapped as a director. The appointments were announced yesterday.
Levinson is chairman of pharmaceuticals company Genentech Inc. He showed his loyalty in 2009 when a federal probe pressured him to choose between keeping his board seat at Apple or at Internet search leader Google Inc, when the companies had become rivals in mobile devices and Web browsers.
Levinson said in a statement that he was honored to be named Apple's chairman.
"Apple is always focused on out-innovating itself ... and that is something I am very proud to be a part of," he said.
Levinson's allegiance may have been especially appreciated by Jobs, who had become convinced that Google stole iPhone's innovative touch-screen operating system to develop its own platform called Android.
Jobs' antipathy toward Google and its former CEO, Eric Schmidt, was well documented during interviews he gave with his biographer, Walter Isaacson. Schmidt was an Apple board member for three years until he resigned in August 2009 as the rivalry between the two companies grew. Levinson resigned from Google's board two months later.
Levinson joined Genentech as a research scientist in 1980 and led it as chief executive from 1995 to 2009. Levinson has been co-lead director on Apple Inc's board since 2005, serving as co-lead director with Avon Products Inc CEO Andrea Jung.
Levinson joined Apple's board in 2000.
Disney's Iger repaired frayed relations between Jobs and Disney after he took the reins of the media company in 2005, first by making ABC shows available on iTunes, and then by leading Disney's acquisition of computer animated movie studio Pixar for USD 7.4 billion. The Pixar deal made Jobs Disney's largest shareholder.
