The Scientist Behind History's Deadliest Accidents

The video explores the unintended consequences of inventions by Thomas Midgley Jr., including tetraethyl lead and CFCs, which caused significant environmental and health issues. Clair Patterson's work revealed the extent of lead pollution, leading to a global phase-out of leaded gasoline. The video highlights the impact of individual actions on the environment and introduces Wren, a climate action organization.

What was Clair Patterson's role in the Manhattan Project?
