The discovery of erbium is generally credited to Carl G. Mosander, although he did not succeed in isolating the element. In 1843 he separated from gadolinite three oxide fractions that he called yttria, erbia, and terbia. Later, what he had called terbia became known as erbia and was shown to contain five distinct rare earths, now called erbia, scandia, holmia, thulia, and ytterbia. Fairly pure erbium oxide was first isolated in 1905; fairly pure erbium was isolated in 1934.
