At an age when some girls only wanted to amuse themselves, Marie-Anne Libert was motivated by a thirst for knowledge: everything interested her, she wanted to know everything[citation needed]. Nature drew her in particular; she spent long hours walking in the area of Malmedy, particularly in the High Fens.
