On 2 February 1939, Pincus and her husband fled from
Nazi Germany to Britain, settling in
Harlech,
Gwynedd, Wales. Her brothers and their families managed to escape and joined her in Harlech. He offered them employment at
Coleg Harlech, In her later autobiography, she reflected on the soothing effect of the local scenery on refugees, the friendly and welcoming atmosphere in Harlech, daily life in a Welsh mining community and
Welsh nationalism. Pincus directed the Bureau until 1965, and continued working there until 1973. Pincus is credited with bringing a "social work ethos" to the institution. Pincus and her Tavistock colleagues developed the idea of "
conjoint therapy," where two caseworkers were assigned to a married couple, 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. 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. She also argued that when a couple had a child and the previously two person relationship changed dynamic, if the father could not allow a third person into the relationship they would be unable to care freely for the infant or provide support for the mother. Pincus edited
Marriage Studies in Emotional Conflict and Growth in 1960. Alongside her work on marriage, Pincus also advocated for intimacy with death and the dying, becoming a leading writer on
bereavement and the importance of
mourning. She wrote about the significance of the loss of a parent in childhood, discussing how for children "the loss of a parent rouses the need to progress, to mature, to be potent." 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. She was critical of old people's residential homes where there was lack of understanding and appreciation of each old person's individuality. == Publications ==
