Actor-director Tim Robbins’ mother, musician Mary Robbins, has passed away, just 12 days after his father, Gil Robbins, died. Robbins said his mother died Sunday of a heart arrhythmia. She was 78. Mary Robbins studied music at the University of California, Los Angeles, and performed professionally in the 1950s. She successfully battled colon cancer through nutrition and alternative medicine, eventually earning a bachelor’s degree in holistic nutrition. She volunteered her services at a clinic near the couple’s Mexico home. She is survived by four children and four grandchildren.
