Actor Ken Weatherwax, who played Pugsley Addams on the 1964 TV series "The Addams Family," has died at the age of 59. According to TMZ, his body was discovered on Sunday in his California home. The cause of death is believed to be a heart attack.

Weatherwax played the youngest son in the creepy, kooky, spooky and altogether ooky TV show during its brief run from 1964-1966. According to a report from Variety, Weatherwax was dedicated to his character even after the show went off the air. He voiced Pugsley again when the show returned as an animated series in the 1970s. He reprised his role once more in the 1977 made-for-TV movie, "Halloween with the New Addams Family" where he played Pugsley Senior.

Eventually, he moved behind the camera to work as a grip (camera and light technician) and a set builder. TMZ notes that he was known to make appearances at "The Addams Family" fan conventions.

While his continued involvement in the role of Pugsley throughout the years proves that he was a true fan of the series, Weatherwax admitted that playing the doofy younger brother of Wednesday Addams (Lisa Loring) was not something he was able to easily get away from.

In an appearance on "The O’Reilly Factor" several years ago, Weatherwax admitted that he faced bullying and mockery after the show ended and he was forced to return to public school.

“Frankly I didn’t deal with it very well,” he told O’Reilly. “I was kicked out of about six or seven school and ended up in the service at the age of 17.”

Still, despite it all, he called his experience working with everyone on the show “great” and “wonderful.”

The actor's family told TMZ that there would be two funerals to honor the late actor -- one for his family and one for his many fans. Weathermax is survived by his brother, fellow film and television star, Joey D. Vieira, 70.
