Lutetium - 71Lu: historical information

  • Discoveror: Georges Urbain and Carl Auer von Welsbach
  • Place of discovery: France, Germany
  • Date of discovery: 1907
  • Origin of name : from the Greek word "Lutetia" meaning "Paris".

In 1907, Georges Urbain described a process by which Marignac's ytterbium (1879) could be separated into the two elements, ytterbium (neoytterbium) and lutetium. These elements were identical with "aldebaranium" and "cassiopeium", independently discovered by von Welsbach at about the same time.
