She was a co-founder of the Family Discussion Bureau, which is now part of the Tavistock and Portman NHS Foundation Trust,[1] and became a leading writer on marital stability and bereavement.
[8] Pincus was described at this early stage of her social work career as "a quite exceptional, unobtrusive, but wise caseworker" with a talent for "glimpsing the human behind the hostile fact," by Enid Balint, who was then the manager of London's inner city Citizens Advice Bureau.
[13] They were part of the British post-war trend of treating marital stability as dependent upon the spouses’ psychological maturity and establishing equal-but-different gender roles between husband and wife.
[14] Pincus felt that in contrast to traditional societies with differentiated roles for the sexes within marriage, modern British couples were navigating the development of their masculinity and femininity without clear societal standards and were therefore experiencing sexual problems and marital failure.
Alongside her work on marriage, Pincus also advocated for intimacy with death and the dying,[17][18] becoming a leading writer on bereavement[19][20] and the importance of mourning.
"[23] Her husband suffered from lung cancer for many years before he died in 1963, and Pincus also drew on her personal experiences of his ill health and death in her writing.
[27][28] Shortly before her death, Pincus published her autobiography: Verloren – gewonnen: Mein Weg von Berlin nach London (1980, in German).
