Apple CEO Steve Jobs

Apple CEO Steve Jobs (September 9, 2009)

President and Michelle Obama: "Michelle and I are saddened to learn of the passing of Steve Jobs. Steve was among the greatest of American innovators - brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it.

By building one of the planet's most successful companies from his garage, he exemplified the spirit of American ingenuity.

By making computers personal and putting the internet in our pockets, he made the information revolution not only accessible, but intuitive and fun. And by turning his talents to storytelling, he has brought joy to millions of children and grownups alike. Steve was fond of saying that he lived every day like it was his last.

Because he did, he transformed our lives, redefined entire industries, and achieved one of the rarest feats in human history: he changed the way each of us sees the world.

The world has lost a visionary. And there may be no greater tribute to Steve's success than the fact that much of the world learned of his passing on a device he invented. Michelle and I send our thoughts and prayers to Steve's wife Laurene, his family, and all those who loved him."

Microsoft Chairman Bill Gates: "The world rarely sees someone who has had the profound impact Steve has had, the effects of which will be felt for many generations to come. For those of us lucky enough to get to work with Steve, it's been an insanely great honor. I will miss Steve immensely."

Mark Zuckerberg: "Steve, thank you for being a mentor and a friend. Thanks for showing that what you build can change the world. I will miss you."

Apple CEO Tim Cook: "Steve Jobs' spirit will forever be the foundation of Apple"

Yahoo Co-Founder Jerry Yang: "Steve was my hero growing up. He not only gave me a lot of personal advice and encouragement, he showed all of us how innovation can change lives. I will miss him dearly, as will the world."

Sen. Chris Dodd: 'One Person Can Make a Difference'

Arnold Schwarzenegger: "Steve lived the California Dream every day of his life and he changed the world and inspired all of us."

George Lopez: "Our Einstein has just passed .. "Vaya Con Dios" Steve Jobs"

Kevin Spacey: "The world lost a true visionary today. Think different."
