Dr Sheina Macalister Marshall OBE FRSE FRS (20 April 1896 – 7 April 1977) was a Scottish marine biologist who dedicated her life to the study of plant and animal plankton. She was an authority on the copepod Calanus. She worked at the Marine Biological Station at Millport, Cumbrae in Scotland from 1922-1964.
Sheina Marshall was born on 20 April 1896 in Rothesay, Scotland, the second daughter of three, to Jean Colville (née Binnie, born 1861/2) and Dr John Nairn Marshall (born 1860) of Mount Stuart House. Marshall's father, a general practitioner, had an interest in natural history and encouraged his daughters' interest in the subject.
Initially Marshall was educated by governesses, later attending Rothesay Academy and St Margaret's School in Polmont. In 1914 she entered the University of Glasgow to study for a BSc in Zoology, botany and physiology. After an interruption in her studies due to World War I she graduated with honours in 1919. She held a Carnegie Fellowship at the University from 1920 to 1922 and worked with the professor of zoology, John Graham Kerr.
In 1922, she took a job at the Marine Biological Station in Millport on the Isle of Cumbrae. where she worked for the rest of her life. From 1928 to 1929 Marshall travelled with Frederick Stratten Russell and J. S. Colman on the Great Barrier Reef Expedition led by Maurice Yonge.
Marshall studied the marine food chain, in particular copepods. It became her life's work. She collaborated for almost 40 years with the chemist, Andrew Picken Orr. Together they studied the plankton and phytoplankton in and around the river Clyde and Loch Striven. They authored several books and many papers together.
In 1949 she was elected a Fellow of the Royal Society of Edinburgh, one of the few female Fellows. Her proposers were Sir John Graham Kerr, James Ritchie, Sir Maurice Yonge, Charles Wynford Parsons and Andrew Orr. In 1963 she was also elected a Fellow of the Royal Society of London.
She retired as Deputy Director of the Station in 1964, but remained there as an Honorary Fellow.
Between 1970 and 1971 she attended at Scripps Institution of Oceanography in the USA and visited the Villefranche-sur-Mer Marine Station in France 1974. In 1987 she published a history of the Marine Station.
In 1949 Marshall, along with Ethel Dobbie Currie, became the first women to be elected Fellows of the Royal Society of Edinburgh and received its Neill Prize in 1971. In 1961 she became a Fellow of the Royal Society. She was awarded the Order of the British Empire in 1966. In 1977 she received an honorary degree from the University of Uppsala, in Sweden.
