Like most of you, I woke to the sad news that Steve Jobs has died in California  at the age of 56. Jobs, who co-founded Apple from a garage in 1976, will be remembered for transforming the company into one of the world's most successful and innovative firms.
He was famously ousted from the company in 1985, something that he later described as the best thing that could have happened to him. "The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life," he said.
By the time he returned to Apple in 1997, the firm was widely regarded as a busted flush. But with Jobs at the helm, Apple mounted an extraordinary comeback, launching a uniquely successful series of products: the iMac, the iPod, the iPhone and, most recently, the iPad. Earlier this year, it briefly unseated Exxon as the most valuable company in the world.
Below are the tributes paid to Jobs by Apple and other figures from the world of technology.
Apple company 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.
Jobs family statement
Steve died peacefully today surrounded by his family. In his public life, Steve was known as a visionary; in his private life, he cherished his family. We are thankful to the many people who have shared their wishes and prayers during the last year of Steve's illness; a website will be provided for those who wish to offer tributes and memories.
Tim Cook, Apple CEO
Apple has lost a visionary and creative genius, and the world has lost an amazing human being. 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.
We are planning a celebration of Steve's extraordinary life for Apple employees that will take place soon.
No words can adequately express our sadness at Steve's death or our gratitude for the opportunity to work with him. We will honor his memory by dedicating ourselves to continuing the work he loved so much.
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 grown-ups 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.
Michael Bloomberg, New York Mayor
Tonight, America lost a genius who will be remembered with Edison and Einstein, and whose ideas will shape the world for generations to come.
Again and again over the last four decades, Steve Jobs saw the future and brought it to life long before most people could even see the horizon.
In New York City's government, everyone from street construction inspectors to NYPD detectives have harnessed Apple's products to do their jobs more efficiently and intuitively.
Bill Gates, Microsoft founder
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. I will miss Steve immensely.
Mark Zuckerberg, CEO of Facebook
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.
