Los Angeles has had years of thick air pollution due to a ballooning population, unregulated industry, a booming car industry, and its natural geography.
The Washington Post described it as “eye-burning, lung-stinging, headache-inducing smog.”
In 1943, during World War II, pollution blanketed the city so intensely residents thought Japan had launched a chemical attack. Over the next three decades, improvements came, but they were slow.
The biggest victory against smog came in 1970. President Richard Nixon created the Environmental Protection Agency, which led to air pollution regulations, and allowed California to make even stricter provisions within its state.

It wasn’t called smog then. The Los Angeles Times once called it “daylight dim out.” But the term “smog” eventually entered the popular vernacular — mixing the words smoke and fog.

At times, the city disappeared entirely.
People felt its effects. Here, women dab their eyes and noses as the world outside appears impenetrable.
In 1949, smoke from a trash dump covered the city. Later, fearing the effects of smog on the city’s inhabitants, Gov. Goodwin Knight restricted the open burning of garbage. It was made illegal in 1958.

On bad days, cars would appear from out of the smog. Visibility was so bad that people had car accidents.
Like this one in 1948.

But it wasn’t until the early 1950s that car exhaust was established as one of the primary causes of smog.
