Apple co-founder and former CEO Steve Jobs has passed away, Apple confirmed on Wednesday.

Jobs battled pancreatic cancer in 2004 and underwent a liver transplant following a leave of absence in 2009. He took another leave of absence in January, 2011, putting COO Tim Cook in his place temporarily. Steve stepped down from his position as CEO in late August, recommending Cook as his successor. Cook is now Apple’s CEO.

“Apple has lost a visionary and creative genius, and the world has lost an amazing human being,” reads a message posted to the Apple Web site. “Those of us who have been fortunate enough to know and work with Steve have lost a dear friend and an inspiring mentor. Steve leaves behind a company that only he could have built, and his spirit will forever be the foundation of Apple.”

Apple’s board of directors offered a statement acknowledging Jobs’ passing:

“We are deeply saddened to announce that Steve Jobs passed away today.“Steve’s brilliance, passion and energy were the source of countless innovations that enrich and improve all of our lives. The world is immeasurably better because of Steve.“His greatest love was for his wife, Laurene, and his family. Our hearts go out to them and to all who were touched by his extraordinary gifts.”
