She was a director of Berkshire Hathaway, owning 2.2 percent of the company worth about $3 billion at the time of her death,[1] making her the 153rd richest person in the world.

Her father, William Hertzog Thompson, was a minister, psychologist, dean at the University of Nebraska-Omaha, and one-time campaign manager for Howard Buffett.

Encouraged by songwriter/musician Neil Sedaka to pursue a singing career,[6] she left her husband and moved to a small apartment in San Francisco with her paramour, John McCabe, in Gramercy Tower on Nob Hill.

Later, she moved into a large condominium on Broadway near Scott Street in Pacific Heights with views of the Golden Gate Bridge and Alcatraz.

According to Roger Lowenstein's 1995 Random House biography, Buffett: The Making of an American Capitalist, while Warren had encouraged Susan to pursue her career in music, he was heartbroken by her move.
