Growing up in the 60s I remember very few people having air conditioning.

I guess thousands died and they just didn’t tell us about it.

Ditto. We didn't have air conditioning at home, in school, at work, or in the car, but I never heard of thousands of people dropping dead from heat back then. Like you, all I can figure is that "they" just didn't bother telling us about it back then.
