...something has already been done, and Dr. Bennett did it. Soon after he joined the Department of Agriculture as a young chemist in 1903, he was sent to Louisa County, Virginia, to see why its soil was so poor. His shocking discovery: the soil was not just poor; most of it was gone, washed down roaring gullies or spirited away by stealthy "sheet erosion." And it was not only the backward South that was threatened with soil destruction. U.S. farmers everywhere, ignoring erosion by water and wind and over-cropping, were squandering the nation's most vital asset...
...1760s, Sir Hugh Smithson, Duke of Northumberland, took up with Elizabeth Keate Macie, reputed descendant of Henry VII. One result: a son, James Smithson, who became a leading chemist, but because of the bar sinister never a duke. Wrote he: "On my father's side I am a Northumberland, on my mother's I am related to kings, but this avails me not. My name shall live in the memory of man when the titles of the Northumberlands and the Percys are extinct and forgotten...
More oil was poured on a still choppy sea by Brazil's Navy Captain Alvaro Alberto da Motta Silva, who took over the Commission's rotating chairmanship. The Captain-a chemist and a physicist, whose naval duties have left him a lot of time for reading-documented the world's urge for peace by citing a long list of immortals: Descartes ("I think, therefore I am"), Virgil (to whom the Captain erroneously ascribed Horace's phrase on war, "matribus detestata"), Thomas Jefferson ("Life, liberty and the pursuit of happiness"), Abraham Lincoln ("We cannot escape history"), Epicurus...
...inventor, Cambridge Chemist Harry Hurst, 34, claimed that he had got rid of the defects in DDT (see below). DDT is 1) slow, and 2) deadly to good as well as bad insects. Dr. Hurst said that some of his mixtures seem to be highly selective, attacking pests but leaving useful insects unharmed. He had also found Activated DDT lethal to some bothersome insects, notably cockroaches, which are not bothered much by DDT alone...
Pfizer brought the price of penicillin down from $20 per 100,000 units to less than $1. This chemical miracle was primarily the work of John L. Smith, the practical-minded chemist who now runs the Pfizer Co. Smith, a shy man with an intense dislike of publicity, was born in Germany, came to the U.S. at the age of three. He learned some chemistry in school, was further helped by his father, who had taken a correspondence course in it. Later, Smith attended Cooper Union, but left before getting his degree to go to work as a laboratory assistant...
