In his final months, Steve Jobs, the celebrated visionary, looked to Walter Isaacson to tell his life story so that the family he left behind would get a chance to know him.

"I wanted my kids to know me, I wasn't always there for them, and I wanted them to know why and to understand what I did," Jobs is now famously quoted as saying. This might shed light as to why a man so notorious about his privacy would at the final moment reveal so much about the family life that he once fiercely protected.

Jobs was adopted by Paul Reinhold Jobs and Clara Jobs right after his birth in 1955. When pressed about his biological parents, the Apple Computer founder always remained adamant that the couple has always been his parents regardless of DNA or heredity. Jobs is survived by his wife of 20 years, Laurene, and their thre children.

Previously, Jobs denied paternity of Lisa Brennan-Jobs, his eldest daughter from a previous relationship, but he later repaired their relationship after going through a court mandated paternity test.

As his biography has been sold and reprinted numerous times since its early release, Jobs' love letter to his wife Maureen has been circulated. "We were guided by our intuition; you swept me off my feet. It was snowing when we got married at the Ahwahnee.

"Years passed, kids came, good times, hard times, but never bad times. Our love and respect has endured and grown. We've been through so much together and here we are right back where we started 20 years ago - older and wiser - with wrinkles on our faces and hearts." continues Jobs in the letter.

"We now know many of life's joys, sufferings, secrets and wonders and we're still here together. My feet have never returned to the ground," Jobs writes, revealing a side to the tireless inventor that the world had never seen.
