Carl Gustaf Mosander

Died 15 Oct 1858 at age 61 (born 10 Sep 1797).Swedish chemist and mineralologist; whose work revealed the existence of numerous rare-earth elements with closely similar chemical properties. In 1839 he discovered lanthanum (La) which is used as a component of misch metal (used for making lighter flints) and rare-earth compounds containing lanthanum are extensively used in carbon lighting applications, especially by the motion picture industry for studio lighting and projection. He discovered other rare earth metals: erbium (Er) in 1842 and terbium (Tb) in 1843. Erbium oxide is rose-pink, and it is used to make pink glass and pink potter's glaze. Terbium oxide has potential as an activator for green phosphors used in colour televisions tubes.[Image: Lanthanum ore.]

Bill, Jim, and Scott were at a convention together and were sharing a large suite on the top of a 75-story skyscraper. After a long day of meetings they were shocked to hear that the elevators in their hotel were broken and they would have to climb 75 flights of stairs to get to their room. Bill said to Jim and Scott, let's break the monotony of this unpleasant task by concentrating on something interesting. I'll tell jokes for 25 flights, and Jim can sing songs for 25 flights, and Scott can tell sad stories the rest of the way. At the 26th floor Bill stopped telling jokes and Jim began to sing. At the 51st floor Jim stopped singing and Scott began to tell sad stories. "I will tell my saddest story first," he said. "I left the room key in the car!"
