Sherwood Schwartz, the producer who created two of the most iconic television shows in U.S. history, The Brady Bunch and Gilligan’s Island, has died at the age of 94, according to a report on NBC.

Robin Randall, Schwartz’s great niece, said he died at 4 a.m. Tuesday.

In 1961, Schwartz won an Emmy for his writing on The Red Skelton Show, but he eventually left that show to focus on his own original shows.

Never a hit with the critics, both Gilligan’s Island and Brady Bunch enjoyed high ratings during their runs in the 1960s and 1970s, respectively.

Both programs have enjoyed long success as reruns as well.
