> Air conditioning: In 1851, Dr. John Gorrie invented a machine to cool air, which laid the groundwork for modern air conditioning and refrigeration
And modern cooling was invented by Carrier, with the original use case to actually control humidity to help the publishing/newspaper industry:
> On December 3, 1911, Carrier presented what is perhaps the most significant document ever prepared on air conditioning – Rational Psychrometric Formulae – at the annual meeting of the American Society of Mechanical Engineers. It became known as the "Magna Carta of Psychrometrics."[8][9] This document tied together the concepts of relative humidity, absolute humidity, and dew-point temperature, thus making it possible to design air-conditioning systems to precisely fit the requirements at hand.
The idea of temperature (first in cinemas and theatres) came later. People under-estimate how much humidity control is needed for comfort: many building codes are adding language to have a standalone whole house dehumidifier.
Its funny because in Florida you kinda need the dehumidifier, it makes a major difference, I have small ones all around the house, but for years I didn't know this. I actually believe wholeheartedly I get sick way less because of it. In other places / states you need a humidifier instead.
