Erik Loomis is a labor historian at the University of Rhode Island, famous for (among other things) his This Day in History Posts.

This Day in Labor History: October 27, 1948. An air inversion trapped the pollution spewed out by U.S. Steel-owned factories in Donora, Pennsylvania. The Donora Smog killed 20 people and sickened 6000 others. Let's talk about American industry poisoned workers and everyone else! pic.twitter.com/sgLcsYzWca— Erik Loomis (@ErikLoomis) October 27, 2019
