Legendary Inventor Steven Paul Jobs, co-founder and former chief executive of tech giant Apple Inc., died on Wednesday at the age of 56 as he sadly could not overcome pancreatic cancer and related health complications.

Apart from leaving behind his wife Laurene, 47, and four children, Steve leaves behind a legacy that includes ground-breaking products in many sectors: iPhone, the best-selling smartphone, App Store, the world's biggest smartphone application store, iTunes, the world's largest online music store and iPad, the best-selling tablet computer. Apple, which stared at bankruptcy just 14 years ago, is now the second most valuable company.

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. The world has lost a visionary. He changed the way each of us sees the world, President Barack Obama said in a statement.

Apple fans will remember Jobs most fondly for his famous keynote speeches -- often referred to as 'Stevenotes' -- where he would announce new products, often holding them aloft to thousands of applauding journalists.

As a sign of respect, the flags at Apple's Cupertino headquarters are at half-mast; fans have begun to leave flowers outside his California home, and others have written messages outside Apple Stores across America.

Apple has lost a visionary and creative genius, and the world has lost an amazing human being. Steve leaves behind a company that only he could have built, and his spirit will forever be the foundation of Apple, Apple Chief Executive Tim Cook said.

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, Cook added.

Jobs' family has released the following 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.

We are grateful for the support and kindness of those who share our feelings for Steve. We know many of you will mourn with us, and we ask that you respect our privacy during our time of grief.

Abdulfattah John Jandali, Steve Jobs' biological father, had no comment Wednesday on the untimely death of his world-famous son, with whom he had no relationship. I really don't have anything to say, said Jandali, vice president at Boomtown Hotel Casino and a former professor at the University of Nevada, Reno. I know the news.
