Rose Scott-Moncrieff

In 2017, the John Innes Centre, where Scott-Moncrieff worked in the 1930s, launched an annual Rose Scott-Moncrieff lecture, with the inaugural lecture given by Hopi Hoekstra.

After her 1937 marriage to Oswald Mapletoft Meares, an electrical engineer, Scott-Moncrieff's anthocyanin research came to an end. The couple had two children, Jean Rosemary Meares and John Willoughby Meares [1]. They moved to India and remained there until Independence in 1947. Besides raising her children she contributed to war-time investigations of camouflage, was Divisional Girl Guide Commissioner for Cawnpore, India and acquired a special insight into Indian education, becoming President of the Women's Section of the All-India Basic Education Conference in January 1945. On their return to England the family settled at 'Windyridge', One Tree Hill Road in Guildford. Her husband died on 28 April 1973.

In the 1930s Rose Scott-Moncrieff and her colleagues published a number of seminal papers in the Biochemical Journal which determined the metabolic sequence and genetic basis of pigment biosynthesis in flowers. Their research laid the foundation for the field of biochemical genetics or molecular biology.

The first crystalline form of primulin was prepared by Scott-Moncrieff in about 1930. This was the first crystalline anthocyanin pigment ever identified.

In 1929 Scott-Moncrieff received a small grant from the Department of Scientific and Industrial Research which enabled her to begin work with JBS Haldane on the molecular biology of flower colour. In the early period of their collaboration she was based in the laboratory of Professor Gowland Hopkins at the University of Cambridge where Haldane was a Reader. Their experiments were mainly carried out at Merton College, Oxford on the chemistry of anthocyanins. Haldane persuaded her to widen her research to include the chemical and genetic study of flower pigmentation. He also introduced her to the geneticists at JIHI where she started on a biochemical survey of related genotypes. Scott-Moncrieff's ability to bring together scientists of a more chemical background with those working on genetics was credited as a large aspect of her success.

Rose Scott-Moncrieff joined the Biochemistry department at the University of Cambridge in 1925 and studied under Muriel Onslow (née Wheldale). She continued Wheldale's research into the genetic control of pigmentation in Antirrhinum majus.

Rose Scott-Moncrieff (Mrs O.M. Meares) (1903-1991), was an English biochemist, credited with founding the science of bio-chemical genetics.

She was born Rose Scott-Moncrieff in 1903. She studied an undergraduate degree at Imperial College London and received a PhD from Cambridge in 1930. However, because she was female she was given only a certificate and she was not allowed to join the university. She worked at the John Innes Horticultural Institution. In the 1930s she worked alongside some of the leading figures in chemistry and genetics. Her recollections of her career were recounted in her book 'The Classical Period in Chemical Genetics. Recollections of Muriel Wheldale Onslow, Sir Robert Robinson and J. B. S. Haldane'.
