Who discovered autism?
Austrian Hans Asperger began using Bleuler's term "autistic psychopaths" when studying an autism spectrum disorder that was eventually named after him, Asperger's Disorder. Th…is disorder was not classified as a different diagnosis from autism until 1994 (American Psychiatric Association, 1994). Around the same time of Asperger's studies in Austria, American Leo Kanner (1943) began studying what he called "early infantile autism." He was also the first person to use the English word "autism" in 1943 when he identified 11 children with very similar behaviors. Many of the characteristics that Kanner used to describe early infantile autism are still used today when describing autism, such as social impairments and insistence on sameness. (MORE)

How was nobelium discovered?
The discovery of element 102 was first announced by physicists at the Nobel Institute in Sweden in 1957. The team reported that they created an isotope with a half-life of 10 …minutes, decaying by emission of an 8.5 MeV alpha particle, after bombarding 244Cm with 13C nuclei. The activity was assigned to 251102 or 253102. The scientists proposed the name nobelium (No) for the new element. Later they retracted their claim and associated the activity to background effects.

Who discovered the element of Oxygen and how was it discovered?
Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. He called the gas "fire air" because of the brilliant sparks it produced when it …came in contact with hot charcoal dust. He repeated this experiment by heating potassium nitrate, mercury oxide, and many other materials and produced the same gas. He collected the gas in pure form using a small bag. He explained the properties of "fire air" using the phlogiston theory, which was soon discredited by Lavoisier. He carefully recorded his experiments in his notes, but waited several years before publishing them. (MORE)

Who discovered potassium and when was potassium discovered?
sir humprhy davy discovered it in 1807 by running an electrical current through some potash (pot-ash) which melted it making potassium Pot ash is made by burning plant leaves …pot ash is the old name for Potassium Hydroxide (KOH) Potassium Hydroxide is a Highly Corrosive substance even when dissolved it heats up to about 150-180 degrees , when molten it is extrmely corrosive its fumes can dissolve lung and organic tissue in seconds becarefull Potassium metal, was first isolated by Sir Humphery Davy in 1807AD by the electrolysis of fused potassium hydroxide. Potassium metal is prepared by heating potassium carbonate with charcoal. 2 C + KCO3 ==> 2 K + 3 CO2 Potassium metal was discovered in 1807 in England by Sir Humphry Davy, who derived it from caustic potash (KOH), by the use of electrolysis of the molten salt with the newly discovered voltaic pile. Before the 18th century, no distinction was made between potassium and sodium. Potassium was the first metal that was isolated by electrolysis. Davy extracted sodium by a similar technique, demonstrating the elements to be different. Potassium was found by Sir Humphry Davy in 1807. He got the element from potash, or KOH. It was discovered in the year 1702 (MORE)
