...Heavy hydrogen was king of the meeting of the American Chemical Society in St. Petersburg, Fla. last week. Its discoverer, Dr. Harold Clayton Urey of Columbia University, opened a heavy hydrogen symposium with a review of its history before 700 members...
Three years ago Professor Fred Allison of Alabama Polytechnic Institute was studying various elements by the magneto-optic method when he got unexpected results which led him to suspect the existence of a hydrogen isotope whose nucleus was twice as heavy as that of ordinary hydrogen. Not long afterward Dr. Urey and two associates concentrated enough of the isotope to identify it. He estimated that heavy hydrogen was present in ordinary hydrogen gas to the extent of about one part in 4,000. He named the new isotope deuterium...
...Among them: Ernest Orlando Lawrence, University of California atom-smasher (TIME, July 3); Columbia's Harold Clayton Urey, discoverer of heavy hydrogen (TIME, July 3); Walter Edward Dandy, Johns Hopkins pathologist (TIME, Jan. 8); Otto Struve, University of Chicago astronomer (TIME...
...their loins for war on their British colleagues. A U. S. discoverer's right to name his own discovery had been challenged from abroad. Scientific relations between the two countries were described as "very tense." Professor Harold Clayton Urey* of Columbia University has baptized the isotope of heavy hydrogen he discovered two years ago deuterium (Greek deuteros, second). He wants deuteron or deuton to be the name of its atomic nucleus. Discussing the matter last December before the Royal Society, Lord Rutherford, head of Cambridge University's Cavendish Laboratory, said: "While we all realize that the first discoverer...
Against such a background Walter Wellman became the talk of two continents when in 1910 he attempted to fly from Atlantic City to Europe in the rebuilt America, with a crew of five and a mascot kitten. The America had a bag 228 ft. long filled with hydrogen generated from sulphuric acid and iron filings. She carried a long control car, the keel of which was a cylindrical fuel tank. From it were suspended a lifeboat and a long cable trailing a cluster of 30 hollow steel cylinders. This last device, called an "equilibrator," was supposed to touch the water...
