Why 1724 is special
He set zero at the coldest temperature he could reproduce with a brine mixture and body temperature near 96. Both reference points were later adjusted, which is why neither lands on a round number now.

The thermoscope of 1593 showed temperature changing without measuring it. Fahrenheit's scale in 1724 supplied the fixed points that turned comparison into measurement.

Fahrenheit fixed zero using a brine freezing mixture and a second point at body temperature. Later recalibration against water's freezing and boiling points shifted both, leaving 32 and 212 rather than round figures.
