How did they make ice, in the days before electricity?
And did they figure it out empirically, prior to the
development of thermodynamic theory?

THAT page is your idea of a helpful answer?
Retorting rCLunbelievable!rCY is a wild understatement.

Offers nothing regarding the innards of the ice makers.
Nor addresses the question of whether the inventors were
educated in thermodynamic theory.

That was easy.

Indeed, brainlessly typing keywords into Google, then copying
URL of pages you didnrCOt read, is never difficult.

In the early days, they cut it out of frozen lakes and rivers and stored it
in ice houses insulated with thick layers of hay.

And did they figure it out empirically, prior to the
development of thermodynamic theory?

Mechanical refrigeration was developed about 1850, but took a while to
become widely commercially available. I think the physics was pretty well understood by that time.

Electricity? I once lived in a house with no electricity supply. We used
a Kerosene fridge. I believe there are also propane fridges.

In the early days, they cut it out of frozen lakes and rivers and stored it in ice houses insulated with thick layers of hay.

Usually a deep hole in the ground, often an impressive stone/brick superstructure over over the top, and a trap corridor with doors each
end to keep any heat out.

There was also a trade in ice from areas where it was cold.

making ice on a commercial scale came well before home fridges - mostly
the ice was for the fish and meat trade, but you could buy in blocks of
ice for domestic use.

There is a pretty good history here ...
