Phyllis Regina Elsa Lewkowitsch (1903–1980), Ph.D., A.R.C.S., was a British research chemist, the daughter of Julius Lewkowitsch and Katherine Julia Morris.[1]
Lewkowitsch was the first female student at the Department of Chemical Engineering, Imperial College London, and graduated top of her year.[2] She continued her father's research into oils and fats, and was a contributor to the 14th edition of the Encyclopædia Britannica (1929–30). In the 1930s she prepared a seventh edition of her father's The Chemical Technology and Analysis of Oils, Fats and Waxes (first edition 1895; sixth edition 1923), but publication was prevented by the Second World War.[3]
By her will she established a bequest to found the Society of Chemical Industry's biennial Julius Lewkowitsch Memorial Lecture in memory of her father.[4]
