Dysprosium history

It is unquestionable that dysprosium was discovered (1886) by de Boisbaudran alone. Having prepared sufficiently pure holmium , the scientist thoroughly studied its spectrum and discovered two new lines which pointed to the presence of an unknown element. After multiple recrystallizations he separated the impurity thus, dysprosium was discovered, as well as holmium. Its name originates from the Greek for difficult to obtain . The name is symbolic since it is characteristic of the REEs history.
