Sir Roger Moore, famous for his role as British secret agent James Bond, has died at age 89 on Tuesday.

Moore’s children, Deborah, Geoffrey and Christian, posted a note on his Twitter page to inform fans of his death from cancer in Switzerland.

The actor was the third man to play Bond, taking on the role after the Sean Connery’s long run. Moore stayed on for a total of seven films in the action franchise between 1973 and 1985. His films as the character included “Live and Let Die” and “The Man with the Golden Gun.”

Moore is perhaps less known for 26 years of work as a Goodwill Ambassador with the charity UNICEF. He became involved in the organization as a result of his long friendship with actress Audrey Hepburn, who spent the last years of her life working with UNICEF. He was knighted on June 14, 2003, for his philanthropic work.

“Thank you Pops, for being you and for being so special to so many people,” his children’s statement said.

The family will have a private funeral in Monaco, in accordance to his wishes.
