If you want a fascinating story telling video with a lot of sciency stuff for the relative layman, here's an excellent one by Veritasium on how it happened. "The Man Who Accidentally Killed The Most People In History" [this video]
Fascinating storytelling with accessible science.

Have you seen this Veritasium video about the man who came up with adding tetraethyllead to gasonline and it's negative impact on humanity? [this video] Given how dangerous lead is in even the tiniest quantities it is really surprising that there has not been more pressure to change that.
Story of inventor of tetraethyllead and its impact.

on HN thread Why did we use leaded petrol for so long? (2017)
Veritasium did a great video on Midgley: [this video] And therein they give the reason why ethanol was passed over: a lot of it is required to be effective (~10% of the fuel mixture), seriously dampening the profit margin of fuel sales! It works, but tetraethyl lead is so much cheaper
Explains why ethanol was passed over for lead.

on HN thread Auto manufacturer family tree: Who owns what?
Oh, the link between GM and leaded gasoline makes more sense in that context. TEL had been identified chemically in the mid-19th century, but General Motors had discovered its effectiveness as an antiknock agent in 1921, after spending several years attempting to find an additive that was both highly effective and inexpensive.

Video treatment of TEL and GM history.

I mean, apparently the inventor of lead additive to gasoline used to pour the chemical over his hands to demonstrate how safe it was -- even though he knew it was actually quite toxic. So there are people who will knowingly give themselves small doses of poison to keep the money flowing. [1] [this video]
Cited for inventor pouring lead additive over hands.

The Man Who Accidentally Killed The Most People In History [this video] > This, my dear friend, is all I can at present recollect on the Subject. You will see by it, that the Opinion of this mischievous Effect from Lead, is at least above Sixty Years old; and you will observe with Concern how long a useful Truth may be known, and exist, before it is generally receiv'd and practis'd on. > Benjamin Franklin, 1786
Cited alongside a Franklin quote on lead.
