Sid Davis, chronicler of childhood menace and jeopardy, has died at 90.

Sid was one of the most distinctive independent filmmakers who entered the nontheatrical film field following World War II. Throughout his career, he expressed concern for the safety and wellbeing of children and teenagers, making some 150 films (the exact total is hard to determine) that rank among the most compelling cautionary works of the 20th century. Though he was a Hollywood insider and worked as John Wayne’s stand-in, he was a self-taught filmmaker, and his films look quite unlike anyone else’s.
There are 25 of his films online at the IA.
