Zgodovina
Ytterbium was discovered by the Swiss chemist Jean Charles Galissard de Marignac in the year 1878.
In 1907, in Paris, George Urbain separated ytterbia into two constituents.
Ytterbium metal was first made in 1937 by Klemm and Bonner by heating ytterbium chloride and potassium together.
A relatively pure sample of the metal was obtained only in 1953.
