I get these commentaries once a week; sometimes they're really interesting, and this one involved two recent threads:
Thomas Midgley : A commentary from Bill Hammack's public radio program You can listen to this commentary at http://www.engineerguy.com 'Two of the greatest environmental threats of the twentieth century - leaded gas and freon - were the work of a single man named Thomas Midgley. Because of these two inventions, a historian described Midgley as having "had more impact on the atmosphere than any other single organism in earth history..." 'There is great irony in Midgley's career: He set out to improve our world, and yet [unintentionaly introduced two signinficant atmospheric pollutants]... 'This irony was reflected in his own demise. In 1940 he contracted polio. He designed a system of ropes and pulleys to help him in and out of bed. One day he became entangled in this network of ropes, and was strangled by his own ingenuity.'
