- Pieces of rare earth metal which was discovered as an impurity in the mineral ytterbia.
- In 1907, the French chemist Georges Urbain separated Marignac's ytterbia into two components : neoytterbia and lutecia.
- All of these researchers found lutetium as an impurity in the mineral ytterbia, which was previously thought to consist entirely of ytterbium.
- He suspected that ytterbia was a compound of a new element that he called " ytterbium " ( in total, four elements were named after the village, the others being yttrium, terbium and erbium ).
- The Austrian chemist Carl Auer von Welsbach independently isolated these elements from ytterbia at about the same time, but he called them aldebaranium and cassiopeium; Urbain and Welsbach accused each other of publishing results based on the other party.
