Steve Jobs, 56, co-founder and former Chief Executive Officer (CEO) of California-based Apple Inc., died last Wednesday after a long battle with a rare form of pancreatic cancer. The news of his death has become, in all probability, the most publicized event of recent times and has certainly spread like wild fire across the Internet. Unfortunately, his biological mother has no clues about it all.

Steve Jobs' biological mother, Joanne Simpson, had to put her son up for adoption after he was born, since she was only a student at the time. Today, however, she is a seriously-ill woman at a nursing home in Los Angeles, with no clue about the fact that her son is no more, reported the Mail Online.

Simpson, 79, is battling an advanced stage of dementia. Due to the condition, she has a drastically reduced mental capacity; she has no idea that her son is dead and knows even less about who she is.

Simpson's son was adopted by Paul and Carla Jobs in 1955. The boy was born to Simpson (at that time Joane Schieble, a graduate student) and Abdulfattah John Jandali, a Syrian international. Since Simpson and Jandali were not married and raising their child would not have been acceptable by the social conventions of each person's communities, they were forced to give their son up for adoption.

Over the years, Jobs reconciled himself with his biological mother but never made contact with his biological father, according to the report. In addition, in 2005, when Jobs delivered the much-talked abotu commencement speech at Stanford, he spoke of how reluctant his mother was when signing the adoption papers, saying that she wanted to make sure that she gave her child away to a well-educated couple. As it turned out, Paul Jobs was a high-school drop-out who became a machinist and his wife Clara never graduated from college, according to the report.

Steve Jobs' biological parents did eventually marry; they had another child - a daughter, Mona Simpson, who went on to become a famous novelist.

My biological mother was a young, unwed college graduate student, said Jobs at the speech at Stanford, She felt very strongly that I should be adopted by college graduates.

As he grew up, Jobs remained in touch with his mother and his biological sister as well. However, his mother's dementia took a toll on her memory, not allowing her to remember anything of her family or herself.

The Daily Mail quoted a source as saying: Steve was one of the richest men in the world, but his wealth couldn't save him and it couldn't save his mother. We used to find her wandering the streets wearing only a house coat with nothing underneath and sometimes we would find her wearing barely anything climbing trees in her bare feet. In the end someone dropped her at a mental hospital as they were so concerned for her wellbeing and then when her daughter found out they eventually moved her to a nursing home. She was a lovely woman so it was very hard to see her demise. Now she is locked in her own body and barely knows who she is let alone Steve anymore.

They had reconnected in later life and it must have been so sad for Steve watching his mum lose her mind, knowing there was nothing he could do about it. It was like a double heartache as there was nothing he could do about his condition either in the end. While we never saw him round her house before they moved her, what we do know is that her rent was paid for as if by magic every month. And now she is in one of the best care homes, so it doesn't take a fool to work out who is paying for it, the source added.

Steve Jobs apparently knew about his birth mother's mental condition and is said to have secretly financed her treatment and care. 

A simple, self-effacing and humble human being, Jobs lived a somewhat ordinary life in his earlier days. His dreams, however, were far less so; they were, in fact big and extraordinary. So much so that one day he founded a company that became one of the biggest technology and consumer products manufacturers the world has known. Over time, Apple Inc., and Jobs would revolutionize the very idea of personal computing.

Jobs married his wife, Laurene, in 1990 and soon became a devoted family man; even more so after the birth of his children - his son Reed and his daughters Erin and Eve.

I realized that I love my life. I really do. I've got the greatest family in the world, and I've got my work. And that's pretty much all I do. I don't socialize much or go to conferences. I love my family, and I love running Apple, and I love Pixar. And I get to do that. I'm very luck(y), Jobs had said in a 2005 interview. This was soon after he was diagnosed with cancer.
