Irene Manton


Irene Manton, FRS FLS was a British botanist who was Professor of Botany at the University of Leeds. She was noted for study of ferns and algae.

Biography

Irene Manton was the daughter of dental surgeon, George Manton and embroidress and designer, and descendant of French aristocracy, Milana Manton. 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.

Academic career

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.

Originally three Georgian town houses, the property was converted into a single building after the University acquired it, also changing the entrance to the much less prepossessing rear of the building. Manton's electron microscopes and associated equipment were located in the basement, where the effects of vibration from traffic, etc. were lowest. The building is now on account of its fine Georgian facade.
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 and where her focus was on ferns and algae. The work with ferns addressed hybridisation, polyploidy, and apomixis and led to her 1950 book, Problems of cytology and evolution in the pteridophyta. As well as engaging chromosomes for the purposes of evolutionary investigation, Manton carried out research into gross morphological structure using the ultraviolet microscope. This venture proved to be an important stepping stone to her later fine structural research of the cell.
Her work on the algae was notable for its use of the electron microscope and her cytological work became known worldwide for the structure of cilia and flagella she revealed. 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.

Honours

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.
In 1969 she was elected a Foreign Honorary Member of the American Academy of Arts and Sciences.
From 1969 - 1972 she was President of the British Pteridological Society.
In 1972, Manton was awarded the Schleiden Medal by the Academy of Sciences Leopoldina.

Legacy

In 1990 the Irene Manton Prize for the best dissertation in botany during an academic year was established by the Linnean Society. The society also sponsors an annual Irene Manton Lecture.
In 1998, the tenth anniversary of her death, the Biological Sciences building at the University of Leeds was re-named the Irene Manton Building in her honour.
The British Phycological Society awards the Irène Manton prize annually for the best postgraduate student presentation at its annual scientific meeting.
