Margaret Lowenfield was born in Lowndes Square in Knightsbridge, London on 4 February 1890, as their second daughter, to a British mother and Polish father.
He soon became a wealthy businessman through several ventures, such as buying up rundown theatres in the West End of London and starting the Kops Brewery in Fulham, selling non-alcoholic beer as the temperance movement took hold.
Lowenfeld was educated at Cheltenham Ladies College, England, with her older sister, Helena Rosa Wright who went on to be an influential figure in birth control and family planning.
She also worked with the American YMCA assisting the Polish Army and POW department in stemming infectious diseases in her father's ancestral town of Chrzanów.
Through this association Lowenfeld developed an interest in psychodynamic psychology as a treatment of shell-shock and learned about the work of Hugh Crichton-Miller who co-founded the Tavistock Clinic.
In 1923 she obtained a Medical Research Council fellowship and Muirhead Scholarship to study at the Royal Hospital for Sick Children, Glasgow where she worked on childhood rheumatism.
[6] Although Lowenfeld's second important book, The World Technique begun in 1956, was partially completed in 1959, it was not published till 1979, six years after her death.
Her obituary, published February 1973 in The Times, commented:- ...bringing a brilliant mind to the study of the psychology of children and to devising methods to identify and eliminate anti-social tendencies at a formative stage and release and develop their highest potentials.
It continued that the practical application of her theories by professionals and local authorities had remarkable success with disturbed children and had made a significant contribution to the health of the community.
[10] After retiring from full-time medical practice, Margaret Lowenfield moved out of London to a house in Cholesbury, Buckinghamshire, which she had purchased back in the 1930s to use as a weekend retreat, following the death of her mother.
