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 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.Since many of the authors have little interest in the history of technology outside of advertising black contributions to it, their stories tend to be fraught with misunderstandings, wishful thinking, or fanciful embellishments with no historical basis.The lack of historical perspective leads to extravagant overestimations of originality and importance: sometimes a slightly modified version of a pre-existing piece of technology is mistaken for the first invention of its type; sometimes a patent or innovation with little or no lasting value is portrayed as a major advance, even if there's no real evidence it was ever used.Most interesting were the reasons they made their choices.What are other people's choices for the most important technologies of the 1900s and your reasons for choosing them?

Such beliefs usually originate in books or articles about black history." I think that the large push in communications technology in the last century were critical in getting us things we've come to depend on today..the TV to Slashdot.What technologies developed in the last century do you think are important?Garrett Morgan's cross-shaped, crank-operated semaphore was not among the first half-hundred patented traffic signals, nor was it "automatic" as is sometimes claimed, nor did it play any part in the evolution of the modern traffic light. The invention of the gas mask predates Morgan's breathing device by several decades. 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.For details see Inventing History: Garrett Morgan and the Traffic Signal. Early versions were constructed by the Scottish chemist John Stenhouse in 1854 and the physicist John Tyndall in the 1870s, among many other inventors prior to World War I. George Washington Carver (who began his peanut research in 1903)? Peanuts, which are native to the New World tropics, were mashed into paste by Aztecs hundreds of years ago. Kellogg, of cereal fame, secured US patent #580787 in 1897 for his "Process of Preparing Nutmeal," which produced a "pasty adhesive substance" that Kellogg called "nut-butter." "Discovered" hundreds of new and important uses for the peanut? The "hydrostatic" lubricator originated no later than 1871. It was Fantus who coined the term "blood bank."
