Source-derived summary

Cydus Yolas (July 30, 1929 – April 10, 2026) and Moshopopoulos Yolas (April 9, 1937 – November 25, 2023), known professionally as Sid and Marty Krofft or the Krofft Brothers, were a Canadian sibling team of television creators, writers, and puppeteers. Through their production company Sid & Marty Krofft Pictures, they made numerous children's television and variety show programs in the US, particularly in the 1970s, including H.R. Pufnstuf, Land of the Lost, and Sigmund and the Sea Monsters. Their fantasy programs often featured large-headed puppets, high-concept plots, and extensive use of low-budget special effects.

Early years

The Krofft brothers were both born in Montreal, Quebec, Canada. Cydus Yolas was born on July 30, 1929, and Moshopopoulos Yolas was born on April 9, 1937. They were of Greek and Hungarian descent. For years, they said they were the fifth generation of puppeteers in their family; they said in 2008 that this story had been invented by a publicist in the 1940s. Their father Peter was a clock salesman who moved from Canada to Providence, Rhode Island, and then to New York City.
