From the Paper:

"Erbium is one of many elements listed in the periodic table, a metallic chemical element specifically (Columbia 15785). Symbolized by the abbreviation Er, most credit the discovery of this element to a scientist named Carl G. Mosander, who although did not isolate the element, located it and separated it from "three oxide fractions" (Columbia 15785). It was not until 1934 that pure erbium was isolated from it's fractions by other scientists (Columbia 15785) allowing for greater exploration into its uses for commercial purposes."
