In page Anna-Teresa Tymieniecka:

"

Anna-Teresa Tymieniecka was born into a noble Polish-Jewish family. She was daughter of Władysław Tymieniecki and Maria Ludwika Loewenstein. Her acquaintance with philosophy started at an early age with reading of the fundamental work of Kazimierz Twardowski, the founder of the Lwów–Warsaw Philosophical School, Zur Lehre vom Inhalt und Gegenstand der Vorstellungen (On the content and object of presentations), as well as works by Plato and Bergson. To the philosophy of the latter she was introduced by her mother, Maria-Ludwika de Lanval Tymieniecka.[citation needed]
