From Easter in 1912, Rosenthal studied natural sciences and philosophy at the Schlesischen Friedrich-Wilhelms-Universität (Silesian Freidrich-Wilhelms-University) in Breslau.

Both alone and together with her former teacher Ferdinand A. Pax, she contributed numerous scientific articles in Adolf Engler's multi-volume publication Das Planzenreich, which originally had aimed to cover all plant species on earth.
