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? 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.

Elijah Mc Coy revolutionized industry in 1872 by inventing the first device to automatically oil machinery? The phrase "Real Mc Coy" arose to distinguish Elijah's inventions from cheap imitations? The oil cup, which automatically delivers a steady trickle of lubricant to machine parts while the machine is running, predates Mc Coy's career; a description of one appears in the May 6, 1848 issue of Scientific American. Robertson of the US army preserved blood in a citrate-glucose solution and stored it in cooled containers for later transfusion. By the mid-1930s the Russians had set up a national network of facilities for the collection, typing, and storage of blood.

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. Bernard Fantus, influenced by the Russian program, established the first hospital blood bank in the United States at Chicago's Cook County Hospital in 1937.

There is no evidence that any commercial railway telegraph based on Granville Woods's patents was ever built. French engineer Henri Giffard successfully flew a powered navigable airship in 1852.Lewis Latimer invented the carbon filament in 1881 or 1882? English chemist/physicist Joseph Swan experimented with a carbon-filament incandescent light all the way back in 1860, and by 1878 had developed a better design which he patented in Britain.On the other side of the Atlantic, Thomas Edison developed a successful carbon-filament bulb, receiving a patent for it (#223898) in January 1880, before Lewis Latimer did any work in electric lighting.Evidence of modern peanut butter comes from US patent #306727 issued to Marcellus Gilmore Edson of Montreal, Quebec in 1884, for a process of milling roasted peanuts between heated surfaces until the peanuts reached "a fluid or semi-fluid state." As the product cooled, it set into what Edson described as "a consistency like that of butter, lard, or ointment." In 1890, George A. Louis, manufactured peanut butter and sold it out of barrels. Carver's work to improve regional farming practices was not of pioneering scientific importance and had little demonstrable impact.To see how Carver gained "a popular reputation far transcending the significance of his accomplishments," read Mackintosh's excellent article George Washington Carver: The Making of a Myth.
