June Foray, the voice...

...of Rocky the flying squirrel and others, died at age 99.

From her obit in the Times (my emphasis):

Ms. Foray began her remarkable 85-year career playing an elderly woman in a radio drama in 1929 at age 12. She portrayed scores of radio characters in the 1930s and ’40s. Over the next 60 years, she provided voices for animated shorts, feature films and television shows, as well as record albums, video games, even talking toys. Her last performance was as Rocky in a 2014 Rocky and Bullwinkle cartoon produced by DreamWorks Animation.

At 94, she became the oldest person to win an Emmy, cited for her Mrs. Cauldron on “The Garfield Show,” and in 2013 she received an Emmy Governors Award.
