英语词汇franklin conductor的起源、历史背景-英语词源词典

Franklin conductor; Franklin stove; etc. Benjamin Franklin (1706–90), one of the broadest and most creative minds of his time—statesman, scientist, writer, printer, and inventor—de- vised the Franklin stove, a great improvement over its predeces- sors, in 1743. This portable, coal-burning iron fireplace had a pipe connecting it to the chimney, producing heat cheaply and relatively efficiently. Franklin’s other inventions include Frank- lin’s bifocals, and his famous experiment with a kite during a thunderstorm in 1762 led to his development of the Franklin lightning rod. Every branch of science held his interest, but Franklin’s contributions to mankind did not end here. Among many civic achievements, he founded America’s first circulat- ing library, set up Philadelphia’s first fire company, established what is now the University of Pennsylvania, organized the American Philosophical Society, wrote and published Poor Ri- chard’s Almanack—which sold 10,000 copies a year—and pub- lished the Pennsylvania Gazette, the most widely circulated newspaper in colonial America. The Franklin tree, or Franklin- ia, is also named after Benjamin Franklin. This species has an unusual history—introduced into cultivation from the wild in 1770 by American’s first botanist, John Bartram, no one has been able to find it in its wild state since.
