Some actors are best known for their stage performances on Broadway. Other actors are better known for their TV appearances. Then there are the actors who become movie stars. It’s rare that an actor can succeed at all three. Actors that can are true legends. Robert Morse was one of those legends.

Back in 1961, Morse was the first actor to portray the character J. Pierrepont Finch on Broadway. He stared as Finch in the musical “How to Succeed in Business Without Really Trying,” and he went on to win a Tony Award for his performance.

Morse played Finch on Broadway through March 1965. Then in 1967, Morse reprised his role as Finch in the movie version of “How to Succeed in Business Without Really Trying.” Although he made the leap from stage to screen, he was far from done with the theater. In 1990, he performed in a one-man show about the life of Truman Capote. His performance in this one-man show, which was called “Tru,” earned him another Tony Award.

Later in life, he made the leap to the small screen staring as Bertram Cooper on the hit show “Mad Men.” He was nominated for a total of 5 Emmys for his performance.

Whether you knew him from the theater, the silver screen or the small screen, you probably recognize his face and some aspect of his career. Unfortunately, talent agency BRS/Gage has confirmed that Morse passed away at the age of 90 years old. According to Jordan Bell of BRS/Gage, Morse “died peacefully at home after a brief illness.”

After hearing about the death of his friend, writer-producer Larry Karaszewski tweeted, “My good pal Bobby Morse has passed away at age 90. A huge talent and a beautiful spirit. Sending love to his son Charlie & daughter Allyn. Had so much fun hanging with Bobby over the years — filming People v OJ & hosting so many screenings (How To Succeed, Loved One, That’s Life).”

“Mad Men” also tweeted about his death writing, “Robert Morse was one of the greats. Rest In Peace.”
