In 1908, Japanese chemist Masataka Ogawa announced that he discovered the 43rd element. However, later analysis indicated the presence of rhenium (element 75), not element 43. In 1922, Walter Noddack, Ida Eva Tacke and Otto Berg announced its separation from gadolinite and gave it the present name. From the Latin word Rhenus meaning Rhine
