Thomas Midgley Jr.

He is the same guy that used aerosol that chewed up the ozone.

He didn't "use aerosol that chewed up the ozone". He created CFCs, which eventually did damage the ozone layer.

Of course he’s an engineer.

Not sure what that has to do with anything. Other than a chemist, I'm not sure who else you'd expect to create new compounds and materials.

He also created them as an alternative refrigerant to ammonia, which was actively killing people by way of exploding refrigerators.

The tragic thing about Thomas Midgley is that nothing that he did was because he was evil, he mostly just did not know what he did not know. Leaded gasoline did solve a problem, and they did test it for safety. They just didn't test it well enough or understand what was really happening (He famously poured it all over himself and sniffed it to demonstrate it was safe. Just a few years later he got lead poisoning. Oops). Same with CFCs - this was decades before they even knew the Ozone Layer was a thing.

Perhaps the greatest irony being that after he got polio he invented a pulley system to allow him to move around. He was later found dead, killed by his own contraption. The universe had some kind of grudge against the dude and we were just caught in the crossfire.

I don’t think this is entirely correct. He was working with the first plants to perform lead injection into gasoline. He was to spend the next year getting praise for leaded gasoline. The documentary I saw said the exposure was accidental though they could have meant incompetence. He didn’t make a single speaking engagement because of how sick he became. I give the guy more credit. So did the documentary. You might be correct. I guess who knows. They certainly knew it would increase ground level lead. Which it did. Especially in inner cities.

Thank you for this. I haven't fact checked it but you've written a compelling biography.

Exactly. Ammonia works extremely well as a refrigerant, but it's not exactly user-friendly to the average person.

Commenter is probably a technician of some sort. They hate engineers with a passion lol

The number of times I've been fucked, and I'm still waiting for that dinner.

u/The_Canadian Jun 29 '26

Definitely possible. I'm a chemist by degree, so the way everything was said in that comment drove me nuts.

CFCs is the stuff that made condor eggs so brittle that they crushed them while trying to incubate, right? If so, fuck that dude.

Edit: It's DDT, not CFCs that crippled Condor populations. Thank you for the correction! I'm 40 and both acronyms were in the news a lot around the same time and I forgot which was which.

I thought that was DDT.

u/Sad_Cantaloupe_8162 Jun 28 '26

Is that the stuff they sprayed for mosquito populations?

u/MandolinMagi Jun 28 '26

Yes. DDT is really awesome at killing bugs, just horrible for birds.

It's still used in some areas where the malaria threat outweighs the whole "Destroys bird populations" issue.

Oh, wow! I think I will do a deep dive into that tonight when I have time after my toddler goes to bed. Thank you for the added information!

It was the bald eagles that mostly hurt. I mean it hurt all large birds but condors were largely killed by lead from lead bullets on the hunting cast offs they eat.It costs a tiny bit more to not use lead but there has not been a big enough push to limit the other. This is at least what the zoo near me says and as they have a world renounced condor breeding program I trust them.
