Regina Kapeller-Adler

Regina Kapeller-Adler, born Regina Kapeller, (28 June 1900 – 31 July 1991) was an Austrian biochemist who, in 1934, devised an innovative test for early pregnancy based on the detection of histidine in urine. As a Jew, she was forced to leave Austria following the country's annexation into Nazi Germany in the Anschluss and went to work with the noted geneticist Francis Crew at the Institute of Animal Genetics at the University of Edinburgh.

She worked at the Edinburgh Royal Infirmary during the Second World War and subsequently joined the pharmacology department of the University of Edinburgh and worked as a lecturer in chemistry. Towards the end of her career, she worked in obstetrics and gynaecology. In 1973, she received the Golden Honorary Diploma, an honorary degree of the University of Vienna, which was presented to her by Austrian biochemist Hans Tuppy.
