A believer in reincarnation as well as God, Browne conducted thousands of hypnotic regressions and hundreds of trance sessions to help people around the world, according to her official biography. She explained on CNN's Larry King Live that she both communicated with the dead and looked into the future.
Her following extended well beyond those she helped directly. Some got to know her through her writings, others through the media -- including appearances on "Unsolved Mysteries," "Loveline with Dr. Drew" and "The Montel Williams Show," on which she was a weekly guest for 17 years.
"I, like so many of you, lost a friend today," Williams said in a posting on Browne's website. "But, as has been for the last 20 years, she'll always remain a part of me."
Born in Kansas City, Missouri, during the Great Depression, Browne first became aware of her psychic abilities at age 3, her bio says.
Browne appeared as herself in several episodes of THE YOUNG AND THE RESTLESS in 2006 and 2010.
Her website does not give a cause, but does say that Browne died at 7:10 a.m. Wednesday at Good Samaritan Hospital in San Jose, California.
