When coal smoke choked St. Louis in 1939

St. Louis on ‘Black Tuesday,’ Nov. 28, 1939. The smoke was so thick that streetlights were needed in the middle of the day.

It was a morning unlike anything St. Louis had ever seen.

Automobile traffic crawled as drivers struggled to peer through murky air. Buses, streetcars and trains ran an hour behind schedule. Downtown parking attendants used flashlights to guide vehicles into their lots. Streetlamps were ignited, and storefront windows blazed with light.

Residents called Nov. 28, 1939, “Black Tuesday.” Day turned to night as thick, acrid clouds blackened the sky. Even at street level, visibility was just a few feet. The air pollution was caused by homes, businesses and factories, which burned soft, sulfur-rich coal for heat and power. The soft coal was cheap and burned easily but produced vast amounts of smoke.

The murky morning was an extreme version of a problem St. Louis and dozens of other American cities had been experiencing for decades. Strict federal air pollution regulations were still 30 years away, and state and local efforts to limit coal smoke had failed miserably.

Today, as the Trump administration works to roll back air pollution limits on coal, the events in St. Louis more than 80 years ago serve as a reminder of how bad a situation can become before people’s objections finally force the government to act. And as I discuss in my book “Black Gold: The Rise, Reign and Fall of American Coal,” those events also highlight how successful that action can be.

The fight for cleaner air is a key part of St. Louis history. Days after Black

New video on Ethyl leaded gasoline

Science communicator Derek Muller of Veritasium posted this video on the history of Ethyl leaded gasoline on Earth Day, April 22, 2022.

A brief history of gasoline

Lies about climate change are only part of the environmental history problem posed by the way that the oil and auto industries told their  stories in books, museum or bus caravans (like the one above.)  A full ‘warts and all’ history is still only barely known.  Jamie Kitman, automotive writer and attorney, created this series  for Jalopnik Magazine.

How big oil knew about climate change


The oil industry was aware of the risks of climate change decades ago.

By Benjamin Franta, Stanford University

Four years ago, I traveled around America, visiting historical archives. I was looking for documents that might reveal the hidden history of climate change – and in particular, when the major coal, oil and gas companies became aware of the problem, and what they knew about it.

I pored over boxes of papers, thousands of pages. I began to recognize typewriter fonts from the 1960s and ‘70s and marveled at the legibility of past penmanship, and got used to squinting when it wasn’t so clear.

What those papers revealed is now changing our understanding of how climate change became a crisis. The industry’s own words, as my research found, show companies knew about the risk long before most of the rest of the world.

On Oct. 28, 2021, a Congressional subcommittee questioned executives from Exxon, BP, Chevron, Shell and the American Petroleum Institute about industry efforts to downplay the role of fossil fuels in climate change. Exxon CEO Darren Woods told lawmakers that his company’s public statements “are and have always been truthful” and that the company “does not spread disinformation regarding climate change.”

Here’s what corporate documents from the past six decades show.

Surprising discoveries

At an old gunpowder factory in Delaware – now a museum and archive – I found a transcript of a petroleum conference from 1959 called the “Energy and Man” symposium, held at Columbia University in New York. As I flipped through, I saw a speech from a famous scientist, Edward Teller (who helped invent the hydrogen bomb), warning the industry executives and others assembled of global warming.
