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]

gollark: That is NOT THE HARD PART.
gollark: (I'm still confused though)
gollark: People have already given helpful suggestions how to, soo...
gollark: Parsing a recipe dump and figuring out the steps to autocraft an item.
