[5] Eisenmann studied chemistry at the Ludwig Maximilian University of Munich.
[1] She finished her dissertation "Zur Strukturchemie binärer und ternärer Verbindungen von Erdalkalimetallen mit Elementen der IV.
[1] Shortly after, she started researching in the newly established group of Herbert Schäfer (chemist) at the Technische Universität Darmstadt.
[1] In 1986, Herbert Schäfer died and Eisenmann continued their joint work.
