President Barack Obama was among the many people who paid tribute to Steve Jobs, calling the Apple co-founder a visionary and great American innovator.

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, Obama said of Jobs, who died on Wednesday.

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.

The president was joined by political, technology, entertainment and business leaders around the world in paying tribute to Jobs. A selection:

BILL GATES, MICROSOFT CO-FOUNDER AND CHAIRMAN

Steve and I first met nearly 30 years ago, and have been colleagues, competitors and friends over the course of more than half our lives. 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 him, it's been an insanely great honor.

STEPHEN ELOP, NOKIA CEO

The world lost a true visionary today. Steve's passion for simplicity and elegance leaves us all a legacy that will endure for generations. Today, my thoughts, and those of everyone at Nokia, are with the friends and family that he leaves behind.

FRENCH PRESIDENT NICOLAS SARKOZY ON FACEBOOK

JOHN LASSETER AND ED CATMULL, CHIEF CREATIVE OFFICER AND PRESIDENT, WALT DISNEY and PIXAR ANIMATION STUDIOS

Steve ... saw the potential of what Pixar could be before the rest of us, and beyond what anyone ever imagined. Steve took a chance on us and believed in our crazy dream of making computer animated films; the one thing he always said was to simply 'make it great.' He is why Pixar turned out the way we did and his strength, integrity and love of life has made us all better people. He will forever be a part of Pixar's DNA.
