Sherwood Schwartz, who created Gilligan's Island and The Brady Bunch, passed away of natural causes Tuesday morning in Los Angeles. He was 94. 

Schwartz's iconic series were often ridiculed throughout the '60s and '70s, but both The Brady Bunch and Gilligan's Island lived on in syndication.

In a 1996 interview, as excerpted by the New York Times, Schwartz said despite its silliness, Gilligan's Island had a deeper underlying theme. "It's one world," he explained. "And we all have to learn to live with each other." Schwartz was also responsible for writing his shows' catchy theme songs.

The Brady Bunch's Florence Henderson tweeted her condolences for Schwartz and his loved ones. "Sherwood had a wonderful family who loved and respected him," she wrote. "I know his Brady Bunch family felt the same way. He will be greatly missed."

Schwartz is survived by his wife, Mildred; three sons, Donald, Lloyd and Ross, and a daughter, Hope Juber.
