Steve Jobs told his daughter she “smelled like a toilet” on his deathbed, a new revelatory memoir detailing their troubled relationship has revealed.

Lisa Brennan-Jobs, who the Apple founder had denied was his daughter, also recalls him telling her “you’re getting nothing” in a disagreement over inheriting his prized Porsche, she writes in her soon-to-be-released memoir Small Fry.

Brennan-Jobs also chronicles in an excerpt of her memoir published Vanity Fair magazine, how her father was sued for child-support payments, claimed he was sterile in a deposition and lied about naming Lisa, one of the first personal computers released by Apple, after her.

“I have a secret. My father is Steve Jobs,” Jobs' daughter also told her school friends, proudly telling them about the Apple Lisa desktop computer.

The 40-year-old also recalls how her mother, Chrisann Brennan, who had a five year on-off relationship with the tech visionary, supplemented her welfare parents until she was aged two by cleaning and waitressing, writing: “My father didn’t help.”

“For him, I was a blot on a spectacular ascent,” she writes, “as our story did not fit with the narrative of greatness and virtue he might have wanted for himself. My existence ruined his streak.”
