Details are leaking out from Walter Isaacson’s highly anticipated biography of Steve Jobs, due out Oct. 24. According to the author of the first authorized telling of Jobs’s life, it appears that the private executive wanted his story told for intensely personal reasons.

A Reuters report Friday revealed that Isaacson last spoke to Jobs a few weeks before his death, when the Apple co-founder was too weak to climb the stairs.

Isaacson’s full account of his last visit with Jobs will appear in the Oct. 17 edition of Time Magazine.

When the author asked why the technology CEO had finally authorized a full biography, Jobs reportedly said, “I wanted my kids to know me.”

He went on, according to the Reuters report, saying: “I wasn't always there for them, and I wanted them to know why and to understand what I did.”

A New York Times report also reveals some private moments from Jobs’s last days, documenting the final good-byes he reached out to make to his closest friends and to his family.

Mona Simpson, Jobs’s sister told the paper, “His tone was tenderly apologetic at the end. He felt terrible that he would have to leave us.”

Meanwhile, people around the world who had never met Jobs continue to mourn in their own ways, with many taking to social networks to quote the technology executive’s Stanford commencement speech.

Some circulated an unreleased version of Apple’s famous ad campaign paying tribute to the “crazy ones” who changed the world. The original spot featured a voiceover from Richard Dreyfuss, but the version passed around Thursday featured a voiceover track from Jobs himself.
