Cole died in San Miguel de Allende, Mexico, her agent, Susie Schwarz at Sbb Partners, told Variety. Her cause of death is currently unknown.
“She was a very eccentric woman and a wonderful woman,” Schwarz said of Cole, who didn’t own a cell phone and shied away from technology.
Cole was born in Memphis, and trained at the Royal Academy of Dramatic Art in London.
She returned to the U.S. in 1964 and appeared in "Romeo and Juliet" at the American Shakespeare Theatre in Stratford, Connecticut.
In 1966, Cole made her Broadway debut in a revival of "The School for Scandal" — just one of the many stage appearances during her career — and then landed a gig as Deborah Mehren on CBS soap opera The Guiding Light.
