By the late 1940's, Los Angeles had experienced several extreme smog days -- or "gas attacks" as they were called back then. Everyone had their eyes on wartime factories that had sprung up and were shooting black plumes into the air, but someone had a feeling that the cause might be something else. Arie Haagen-Smit, a Dutch professor at Caltech who would later be deemed the "father of air pollution," was technically supposed to be studying the taste and smell of pineapples when he first began to conduct research into smog. Through letters and interviews with Caltech faculty and historians, we piece together how Haagen-Smit discovered the recipe to smog, and how after he published his results, people weren't exactly ready to hear that their beloved cars were at the root of the problem.

LA Times Studios launched “Smoglandia" on Boiling Point Podcast, a new limited narrative series hosted by award-winning Los Angeles Times columnist Patt Morrison. The podcast traces the rise, impact and eventual retreat of Los Angeles’ most insidious form of pollution: smog.

Through the words and insights of scientists, policymakers, filmmakers and artists who lived through the city’s worst air-quality days, the series explores how Los Angeles became a testing ground for environmental regulation, and how science and innovation transformed public health. At a time when hard-earned progress against smog faces new setbacks, “Smoglandia” examines a landmark victory for the City of Angels, and, through clearer air, looks forward to the lessons still to be learned — and the battles yet to come.

The first episode explores the origins of smog in L.A., featuring Natural History Museum associate curator Dr. Regan Dunn explaining how research at the La Brea Tar Pits uncovered evidence that humans have been creating pollution in the region for thousands of years. Listeners will also hear from renowned artist Helen Pashgian, who recounts growing up in Altadena in the 1940s, during a time when local wartime industries took a toll on her health and obscured the once-glorious vistas.

Additional podcast guests will include actor and climate activist Jane Fonda, U.S. Senator Adam Schiff, L.A. County Supervisor Janice Hahn, and other influential voices behind the city’s ongoing battle with air quality.

“Smoglandia” is presented as a special season of The Times’ “Boiling Point” environmental podcast.
