In
Lisbon Ulrich worked with the
Juventude Independente Catolica Feminina (Independent Catholic Women's Youth). However, in 1950 her father was appointed for a second term as ambassador to London and she again accompanied him. Having decided that she should work in the field of education, which in Portugal at that time was very poor, she took advantage of her stay in London to prepare for her project of establishing a school for kindergarten teachers. She visited
Montessori schools in London and other schools in Paris. She studied the history of education, reading works by pioneers such as
Jean-Jacques Rousseau,
Friedrich Fröbel,
Johann Heinrich Pestalozzi,
Ovide Decroly,
Édouard Claparède and
Célestin Freinet. She maintained regular contact with the ''Mouvement Chrétien de l'Enfance'' (Christian Children's Movement) in Paris. Returning to Portugal, Ulrich opened in Lisbon one of the first schools for teachers in Portugal with, initially, just 13 student teachers. In 1957, she founded the
Associação de Pedagogia Infantil (Association of childhood teaching). In 1957-58, she established
O Nosso Jardim (Our Garden), where children, together with the trainee teachers and in close relationship with the parents, studied in an open environment. ==Later life==
