This sizzling summer seems a fitting season to recall the almost forgotten story of John Lee Pratt and the Frigidaire, one of the first "mechanical" refrigerators.
In 1919 Mr. Pratt, a King George County boy who would become a multi-millionaire and owner of Chatham Manor, was a General Motors engineer.
That same year GM had produced the Frigidaire, one of the first mechanical refrigerators for home use. They were called "mechanical" because some were powered by electricity, others by gas.
