[1] Born 28 January 1912 in Amsterdam, Tante Leen didn't perform live until she was 43-years of age.
Regular custodians of the café in which she worked signed her up for a talent search one day which was being initiated by record label Bovema in order to find the best voice of the Jordaan.
[2] Tante Leen frequently performed together with Johnny Jordaan and was often accompanied by famed accordion player Jan Schallig.
Her song 'Ook kleine kinderen worden groot' (English: Small children do grow up) is dedicated to him.
In 1968 she was selected to represent the Netherlands the annual Eurovision Song Contest but she declined the invitation.
