Question: What did Bell create in 1881?

Bell is also credited with developing one of the early versions of a metal detector in 1881. The device was quickly put together in an attempt to find the bullet in the body of U.S. President James Garfield. According to some accounts, the metal detector worked flawlessly in tests but did not find the assassin's bullet partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. The president's surgeons, who were skeptical of the device, ignored Bell's requests to move the president to a bed not fitted with metal springs. Alternatively, although Bell had detected a slight sound on his first test, the bullet may have been lodged too deeply to be detected by the crude apparatus.

Question: Bell gave his story about trying to find the bullet to the American Association for the Advancement of what?

Bell's own detailed account, presented to the American Association for the Advancement of Science in 1882, differs in several particulars from most of the many and varied versions now in circulation, most notably by concluding that extraneous metal was not to blame for failure to locate the bullet. Perplexed by the peculiar results he had obtained during an examination of Garfield, Bell "...proceeded to the Executive Mansion the next morning...to ascertain from the surgeons whether they were perfectly sure that all metal had been removed from the neighborhood of the bed. It was then recollected that underneath the horse-hair mattress on which the President lay was another mattress composed of steel wires. Upon obtaining a duplicate, the mattress was found to consist of a sort of net of woven steel wires, with large meshes. The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect." In a footnote, Bell adds that "The death of President Garfield and the subsequent post-mortem examination, however, proved that the bullet was at too great a distance from the surface to have affected our apparatus."

The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect." <hl> In a footnote , Bell adds that "The death of President Garfield and the subsequent post-mortem examination, however, proved that the bullet was at too great a distance from the surface to have affected our apparatus." <hl>

Bell's own detailed account, presented to the American Association for the Advancement of Science in 1882, differs in several particulars from most of the many and varied versions now in circulation, most notably by concluding that extraneous metal was not to blame for failure to locate the bullet. Perplexed by the peculiar results he had obtained during an examination of Garfield, Bell "...proceeded to the Executive Mansion the next morning...to ascertain from the surgeons whether they were perfectly sure that all metal had been removed from the neighborhood of the bed. It was then recollected that underneath the horse-hair mattress on which the President lay was another mattress composed of steel wires.

Question: Who wrote the paper laying out hydrofoils and hydroplanes?

The March 1906 Scientific American article by American pioneer William E. Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement. Based on information gained from that article he began to sketch concepts of what is now called a hydrofoil boat. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft.

Question: In what country did Baldwin and Forlanini get together?

During his world tour of 1910–11, Bell and Baldwin met with Forlanini in France. They had rides in the Forlanini hydrofoil boat over Lake Maggiore. Baldwin described it as being as smooth as flying. On returning to Baddeck, a number of initial concepts were built as experimental models, including the Dhonnas Beag, the first self-propelled Bell-Baldwin hydrofoil. The experimental boats were essentially proof-of-concept prototypes that culminated in the more substantial HD-4, powered by Renault engines. A top speed of 54 miles per hour (87 km/h) was achieved, with the hydrofoil exhibiting rapid acceleration, good stability and steering along with the ability to take waves without difficulty. In 1913, Dr. Bell hired Walter Pinaud, a Sydney yacht designer and builder as well as the proprietor of Pinaud's Yacht Yard in Westmount, Nova Scotia to work on the pontoons of the HD-4. Pinaud soon took over the boatyard at Bell Laboratories on Beinn Bhreagh, Bell's estate near Baddeck, Nova Scotia. Pinaud's experience in boat-building enabled him to make useful design changes to the HD-4. After the First World War, work began again on the HD-4. Bell's report to the U.S. Navy permitted him to obtain two 350 horsepower (260 kilowatts) engines in July 1919. On September 9, 1919, the HD-4 set a world marine speed record of 70.86 miles per hour (114.04 kilometres per hour), a record which stood for ten years.

Curtiss, a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere, and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge, an official observer from the U.S. Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. Baldwin, the first Canadian and first British subject to pilot a public flight in Hammondsport, New York, and J.A.D. McCurdy —Baldwin and McCurdy being new engineering graduates from the University of Toronto.

Curtiss <hl>, a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere, and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge, an official observer from the U.S. Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. Baldwin, the first Canadian and first British subject to pilot a public flight in Hammondsport, New York, and J.A.D. McCurdy —Baldwin and McCurdy being new engineering graduates from the University of Toronto.

Question: What did the AEA work on after kites?

The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America.[N 24] [N 25] The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. [N 26] The White Wing and June Bug were to follow and by the end of 1908, over 150 flights without mishap had been accomplished. However, the AEA had depleted its initial reserves and only a $15,000 grant from Mrs. Bell allowed it to continue with experiments. Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908.

Question: What did the AEA name their last plane?

Their final aircraft design, the Silver Dart, embodied all of the advancements found in the earlier machines. On February 23, 1909, Bell was present as the Silver Dart flown by J.A.D. McCurdy from the frozen ice of Bras d'Or, made the first aircraft flight in Canada. Bell had worried that the flight was too dangerous and had arranged for a doctor to be on hand. With the successful flight, the AEA disbanded and the Silver Dart would revert to Baldwin and McCurdy who began the Canadian Aerodrome Company and would later demonstrate the aircraft to the Canadian Army.

Question: What kind of parents did Bell state were more prone to having deaf children?

Bell was connected with the eugenics movement in the United States. In his lecture Memoir upon the formation of a deaf variety of the human race presented to the National Academy of Sciences on November 13, 1883 he noted that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that couples where both parties were deaf should not marry. However, it was his hobby of livestock breeding which led to his appointment to biologist David Starr Jordan's Committee on Eugenics, under the auspices of the American Breeders' Association. The committee unequivocally extended the principle to man. From 1912 until 1918 he was the chairman of the board of scientific advisers to the Eugenics Record Office associated with Cold Spring Harbor Laboratory in New York, and regularly attended meetings. In 1921, he was the honorary president of the Second International Congress of Eugenics held under the auspices of the American Museum of Natural History in New York. Organisations such as these advocated passing laws (with success in some states) that established the compulsory sterilization of people deemed to be, as Bell called them, a "defective variety of the human race." By the late 1930s, about half the states in the U.S. had eugenics laws, and California's compulsory sterilization law was used as a model for that of Nazi Germany.
