Welsbach, Baron Carl Auer von (1858-1929), an Austrian chemist. During the 1880's in the laboratory of Robert Wilhelm Bunsen, inventor of the Bunsen burner, he did research on rare-earth elements and their compounds. Von Welsbach noted that some of the compounds burned brilliantly, and he began to use them in gaslight appliances he invented, including the gas mantle. He discovered neodymium and praseodymium (1885), two of the rare-earth elements. In 1907, von Welsbach and G. Urbain (working independently) discovered lutetium and isolated ytterbium, two more rare-earth elements.
He's ventured to the abyss of black holes, wagered on the information paradox and floated around in zero gravity. Meet the man, the legend, the super scientist: Stephen Hawking.
He was born exactly 300 years after Galileo died. He has yet to be awarded a Nobel Prize, although he was awarded a guest spot on “The Simpsons.” What else do you know (or not know) about this acclaimed physicist?
