Celebrating the Anniversary of a Discovery That's Completely Changed the Built Environment

The birth of air conditioning can be traced to July 17, 1902, when a junior engineer named Willis Carrier drew the "blueprints for newfangled equipment to temper the air...a solution so simple that it had eluded everyone from Leonardo da Vinci
to the naval engineers ordered to cool the White House when President
James A. Garfield was dying: controlling humidity."

Barron describes the dilemma that Carrier, "a junior engineer from a furnace company," was trying to solve when he devised a system involving "fans, ducts, heaters and perforated pipes" for the the second floor of a Brooklyn printing plant. 

Needless to say, "It was a world-changing innovation," notes Barron.

"'Air-conditioning, in the broad
sense, had a profound effect on the way people lived and worked,' said
Bernard A. Nagengast, an engineering consultant who specializes in the
history of air-conditioning and heating. 'It allowed industry to operate
in ways it couldn't operate before, in places it couldn't operate
before.'"

"It all but redefined Florida and Houston and the rest of
the Sun Belt. 'And Singapore, sometimes called the air-conditioned
nation,' said Eric B. Schultz, a former Carrier Corporation executive
and author of a recently published company history."

"And, Mr.
Schultz said, the Internet, because air-conditioning minimized dust,
making possible the so-called clean rooms for computer manufacturers and
electronics companies."
