Nancy Marchand (June 19, 1928 – June 18, 2000) was an American actress. She began her career in theatre in 1951. She was perhaps most famous for her television portrayals of Margaret Pynchon on Lou Grant and Livia Soprano on The Sopranos.
Marchand suffered from both lung cancer and emphysema and died on June 18, 2000 in Stratford, Connecticut, just one day before her 72nd birthday. Her character's death was written into the third season story line of The Sopranos. Her husband of 48 years, actor Paul Sparer (1923–1999), had died the previous year, also from cancer. The couple had three children: Katie, an actress, David (Rosebud), a lawyer, and Rachel Sparer Bersier, an opera singer. Marchand was posthumously inducted into the American Theatre Hall of Fame.
