He was dead on Christmas day.
Lee Mendelson, the producer behind more than 50 animated TV specials featuring Charlie Brown and the “Peanuts” gang, died on Christmas Day at his home in Hillsborough, Calif., after a long battle with cancer. He was 86.
Mendelson also wrote the lyrics to “Christmas Time Is Here,” a song featured in “A Charlie Brown Christmas,” the 1965 special that turned “Peanuts” into a TV staple. “Charlie Brown Christmas” brought Mendelson the first of his 12 Emmys. The last came in 2015 for “It’s Your 50th Christmas, Charlie Brown.” Mendelson’s work with animator Lee Melendez also brought him four Peabody Awards, an Oscar nomination and two Grammy noms.
