Early life

She was thus the stepdaughter of Elizabeth Taylor and of Sybil's second husband Jordan Christopher, both actors. Burton earned a bachelor's degree in Russian Studies and European History from Brown University in 1979, where she was on the board of Production Workshop, one of the university's student theater groups, and a master's degree from Yale School of Drama in 1982. Brown awarded Burton an honorary doctorate in 2007.
