More than 50 years later came surgery on the open heart, pioneered by John Lewis, C. Werner von Siemens pioneered the use of an electrified third rail as a means for powering railway vehicles when he demonstrated an experimental electric train at the 1879 Berlin Industrial Exhibition.
Walton Lillehei (often called the "father of open heart surgery") and John Gibbon (who invented the heart-lung machine). In the US, English-born Leo Daft used a third-rail system to electrify the Baltimore & Hampden lines in 1885.

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.
Belgian-born Charles van Depoele, who earned 240 patents in electric railway technology and other fields, set up trolley lines in several North American cities by 1887. The fastest performance of a computer application in 1989 was 6 billion floating point operations per second (6 Gflops), achieved by a team from Mobil and Thinking Machines Corp. The first reference to what seems to be a fountain pen appears in an Arabic text from 969 AD; details of the instrument are not known. A small rubber platform invented by Scotsmen William Bloxsom and Arthur Douglas was the world's first patented golf tee (British patent #12941 of 1889).
In February 1888, a trolley system designed by Frank Sprague began operating in Richmond, Virginia. Was Miles the first to patent a self-closing shaft door? Steam-powered hoisting devices were used in England by 1800. on a 64,000-processor "Connection Machine" invented by Danny Hillis. The first such contraption patented in the US was the work of William P. The fire escape with a "lazy-tongs" type ladder, more similar to Winters' patent, was pioneered by Httman and Kornelio in 1849 (US patent #6155). In 1813, British army captain George Manby created the first known portable fire extinguisher: a two-foot-tall copper cylinder that held 3 gallons of water and used compressed air as a propellant. Hall introduced no major class of additive, certainly not meat curing salts (which are ancient), protein hydrolysates (popularized by Julius Maggi as flavor enhancers in 1886), emulsifiers and antioxidants (lecithin, for example, was used in both roles before Lloyd Hall had any patents in food processing). A French "Bion" pen, dated 1702, represents the oldest fountain pen that still survives. The first known tee to penetrate the ground, in contrast to earlier tees that sat on the surface, was the peg-like "Perfectum" patented in 1892 by Percy Ellis of England. An early US patent for a recognizably modern hairbrush went to Hugh Rock in 1854 (US Design Patent no.
Of the hundreds of inventors granted patents for early airship designs and modifications, few succeeded in building or flying their craft.
There doesn't appear to be any record of a "Pickering Airship" ever getting off the ground.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.The object of my invention is to suspend clothing in close relation to a stove by means of frames so constructed that they can be readily placed in proper position and put aside when not required for use. A Frenchman named Pochon in 1799 built the first known tumble dryer — a crank-driven, rotating metal drum pierced with ventilation holes and held over heat. ) of time, at least we know that US patent #20811 for "Dust-pan" was granted to T. [return to top]Did Granville Woods invent the electric trolley car, the overhead wire that powers it, or the "troller" wheel that makes contact with the trolley wire, in 1888? The vehicle's two electric motors collected power through contact wheels rolling atop a pair of overhead wires.Electric tumble dryers appeared in the first half of the 20th century. The earliest patentee of an electric trolley in the United States appears to be Eugene Cowles (#252193 in 1881), followed by Dr. Finney (#268476 in 1882) who operated an experimental trolley car near Pittsburgh, PA in the summer of 1882. Henry established in Kansas City, MO, the first overhead-wire electric transit system (New England Magazine, Apr 1891, p.192) to enter regular service in the United States.Latimer also did not come up with the first screw socket for the light bulb or the first book on electric lighting. Decades before that, the Spaniard Francisco Romero carried out the first successful pericardial surgery of any type, incising the pericardium to drain fluid compressing the heart.
