Heather North, the longtime voice of Daphne on “Scooby-Doo,” has died at 71, according to the Hollywood Reporter. North passed away at her home in California after a long illness.
“Beginning in 1970 with the second season of Scooby-Doo, Where Are You!, North voiced Daphne Blake, one of the two female members of the teenage investigative team. Whether it was a new animated series or straight-to-video films, she’d portray the character on and off over the next 30-plus years. Her final credit was for 2003’s Scooby-Doo! and the Monster of Mexico.” (source)
