In 1990, Shepherd played the mother of Lorraine Bracco’s Karen Hill in Martin Scorsese’s mob crime drama “Goodfellas.” She also portrayed the recurring character of Carmela Soprano’s mother Mary DeAngelis in the HBO drama “The Sopranos.”

Shepherd was born Suzanne Stern on Oct. 31, 1934. After graduating from Bennington College, she studied under the renowned acting teacher Sanford Meisner. She made her onscreen debut in the Julia Roberts-led romantic comedy “Mystic Pizza” in 1988. Shepherd then had small roles in 1988’s “Working Girl,” alongside Melanie Griffith and Harrison Ford, and in 1989’s comedy film “Uncle Buck.” After appearing in “Goodfellas,” she was featured in “Jacob’s Ladder,” Adrian Lyne’s 1997 remake of “Lolita” and Darren Aronofsky’s psychological thriller “Requiem for a Dream.”

Besides “The Sopranos,” Shepherd appeared on television in several episodes of the “Law & Order” universe and most recently she was on the CBS police drama series “Blue Bloods.”

On top of her acting career, Shepherd served as an acting instructor for over four decades, having taught at Trinity Square Conservatory, Hartman Conservatory, the Berghof Studio and her own studio in New York City. Some of Shepherd’s former students include “Law & Order” actor Christopher Meloni, Tony-winning actor Joan Allen and two-time Emmy winner Bebe Neuwirth.
