Irene Manton, FRS[1] FLS (born Irène Manton; 17 April 1904, in Kensington – 13 May 1988) was a British botanist who was Professor of Botany at the University of Leeds. She was noted for study of ferns and algae.


Irene Manton was the daughter of dental surgeon, George Manton and embroidress and designer, and descendant of French aristocracy, Milana Manton (née D'Humy). Her first name was originally pronounced and spelled in the French manner; but at 18 she dropped this and opted for "Irene". Her sister was the entomologist Sidnie Manton FRS. She was educated at the Froebel Demonstration School and St. Paul's Girls' School, Hammersmith.[2]

Academic Career[edit]

In 1923 Manton attended Girton College, Cambridge. She found Cambridge unsatisfying, in part because the university as a whole was not yet welcoming of women, and later went on to study with Gustaf Otto Rosenberg in Stockholm. Manton obtained a lecturing position at the University of Manchester in December 1928. In June 1930 she received her PhD, with her thesis being on Cruciferae. She had to apply for special permission to continue her PhD studies away from Cambridge when she obtained the position at Manchester.[3]

Much of her academic career was spent at the University of Leeds where she was Professor of Botany from 1946 until 1969 and Professor Emeritus thereafter[4] and where her focus was on ferns and algae. The work with ferns, which addressed hybridisation, polyploidy, and apomixis, included her 1950 book, Problems of cytology and evolution in the pteridophyta. Her work on the algae was notable for its use of the electron microscope with her cytological work known worldwide for the structure of cilia and flagella she revealed.[1][5] She was author or co-author of over 140 scientific publications.

Irene Manton bequeathed her collection of modern and oriental art to the University of Leeds. Many of these pictures hung on the walls of Botany House in the University of Leeds during her career there.[6]


In 1969 Manton shared the Linnean Medal with Ethelwynn Trewavas.

She was the first female President of the Linnean Society of London, being elected in 1973 and serving until 1976.

She was elected a Fellow of the Royal Society in March 1961 for her work on the ultramicroscopic structure of plants and on their evolution.[7]

In 1969 she was elected a Foreign Honorary Member of the American Academy of Arts and Sciences.[8]

In 1972, Manton was awarded the Schleiden Medal by the Academy of Sciences Leopoldina.[9][10]

In 1990 the Irene Manton Prize for the best dissertation in botany during an academic year was established by the Linnean Society.

In 1998, the tenth anniversary of her death, the Biological Sciences building at the University of Leeds was named the Irene Manton Building in her honour.[4]

The British Phycological Society awards the Irène Manton prize annually for the best postgraduate student presentation at its annual scientific meeting.[11]
