The man behind the genius will soon be revealed as Steve Job's official biography has been expedited and will be released on Oct.24.

The long anticipated biography authorized by Steve Jobs and written by Walter Isaacson, the former managing editor of Time Magazine, is said to reveal many of the personal details that Jobs has kept hidden for years.

In the weeks before his death, when Jobs was too weak and frail to climb stairs, he confessed in his final interview with Isaacson that he wanted his children to understand why he wasn't always there for them.

I wanted my Kids to know me, Jobs said when Isaacson asked him why agreed to unleash a tell-all biography after living a private, almost ascetic life, Reuters reported.

Isaacson visited Jobs for the last time a few ago in a downstairs bedroom curled up in pain. He was too weak to climb stairs, according to Isaacson but his mind was still sharp and humor vibrant.

The book is based on more than forty interviews with Jobs conducted over two years-as well as interviews with more than a hundred family members, friends, adversaries, competitors, and colleagues, the book's publisher Simon & Schuster wrote in the synopsis.

Although Jobs cooperated with this book, he asked for no control over what was written nor even the right to read it before it was published. He put nothing off-limits. He encouraged the people he knew to speak honestly. And Jobs speaks candidly, sometimes brutally so, about the people he worked with and competed against. His friends, foes, and colleagues provide an unvarnished view of the passions, perfectionism, obsessions, artistry, devilry, and compulsion for control that shaped his approach to business and the innovative products that resulted.

The biography has already made it to the top of Amazon's best-seller list based on pre-purchase orders. 

Apple's co-founder and visionary, Jobs, passed away on Wednesday aged 56 after losing a fierce battle against pancreatic cancer.

The news of his death was announced in a brief statement by Apple, the company he co-founded with his school friend Stephen Wozniak in 1976.

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, the statement said.

Jobs has battled cancer since 2004 and underwent a liver transplant in 2009, which is when he announced he had health problems and needed to take a short leave of absence. Despite his battle, Jobs continued to be the face of the company, until six weeks ago when he passed on his title as CEO to Tim Cook.

I have always said that if there ever came a day when I could no longer meet my duties and expectations as Apple's C.E.O., I would be the first to let you know, Mr. Jobs said in a letter released by the company. Unfortunately, that day has come.

Jobs, who left with a net worth of $8.3 billion has an entire personal computer industry that has shaped the face of digital technology throughout the years. Not only did he mastermind the Mac computer for easier computer use, with it he left behind the iPod, iPad and iPhone that have become features of peoples daily lives.
