1# George Washington Carver-NO NOT PEANUT BUTTER AS KELLOG AND THE MAYANS DID THAT! "Discovered" hundreds of new and important uses for the peanut? Fathered the peanut industry? Revolutionized southern US agriculture? Nope. Research by Barry Mackintosh, who served as bureau historian for the National Park Service (which manages the G.W. Carver National Monument), demonstrated the following: Most of Carver's peanut and sweet potato creations were either unoriginal, impractical, or of uncertain effectiveness. No product born in his laboratory was widely adopted. The boom years for Southern peanut production came prior to, and not as a result of, Carver's promotion of the crop. Carver's work to improve regional farming practices was not of pioneering scientific importance and had little demonstrable impact. 2# Elijah McCoy-The oil cup, which automatically delivers a steady trickle of lubricant to machine parts while the machine is running, predates McCoy's career; a description of one appears in the May 6, 1848 issue of Scientific American. The automatic "displacement lubricator" for steam engines was developed in 1860 by John Ramsbottom of England, and notably improved in 1862 by James Roscoe of the same country. The "hydrostatic" lubricator originated no later than 1871. Variants of the phrase Real McCoy appear in Scottish literature dating back to at least 1856 well before Elijah McCoy could have been involved. 3# Lewis Latimer-The earliest evidence for a light bulb screw base design is a drawing in a Thomas Edison notebook dated Sept. 11, 1880. It is not the work of Latimer, though: Edison's long-time associates, Edward H. Johnson and John Ott, were principally responsible for designing fixtures in the fall of 1880. Their work resulted in the screw socket and base very much like those widely used today. R. Friedel and P. Israel, Edison's Electric Light: Biography of an Invention, (New Brunswick, NJ: Rutgers Univ. Press, 1986). The 1880 sketch of the screw socket is reproduced in the book cited above. 4# Greenville Woods- Granville Woods prevented railway accidents and saved countless lives by inventing the train telegraph (patented in 1887), which allowed communication to and from moving trains? Nope. The earliest patents for train telegraphs go back to at least 1873. Lucius Phelps was the first inventor in the field to attract widespread notice, and the telegrams he exchanged on the New York, New Haven & Hartford railroad in January 1885 were hailed in the Feb. 21, 1885 issue of Scientific American as "perhaps the first ever sent to and from a moving train." Phelps remained at the forefront in developing the technology and by the end of 1887 already held 14 US patents on his system. He joined a team led by Thomas Edison, who had been working on his "grasshopper telegraph" for trains, and together they constructed on the Lehigh Valley Railroad one of the only induction telegraph systems ever put to commercial use. Although this telegraph was a technical success, it fulfilled no public need, and the market for on-board train telegraphy never took off. There is no evidence that any commercial railway telegraph based on Granville Woods's patents was ever built. Air breaks In 1869, a 22-year-old George Westinghouse received US patent #88929 for a brake device operated by compressed air, and in the same year organized the Westinghouse Air Brake Company. Many of the 361 patents he accumulated during his career were for air brake variations and improvements, including his first "automatic" version in 1872 (US #124404). ==== Please help me with 6 more overrated blacks!!! Of course nearly all blacks are overrated, but I want good ones. More scientist, Inventors, explorers. Is what I want.
