Apple visionary Steve Jobs died Wednesday at age 56.

The co-founder transformed the way we see technology today with the introduction of the iMac, iPod and iPhone.

Jobs had been battling a rare form of pancreatic cancer. Apple's board of directors said in a statement:

    "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."

Jobs beat a form of pancreatic cancer in 2004 and had a liver transplant in 2009. Then on August 24, 2011, he stepped down as Apple's chief executive, stating in his resignation letter, "I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple's CEO, I would be the first to let you know. Unfortunately, that day has come."
