Over approximately two decades she devised various handling and drying techniques and collected and documented some 13,500 specimens, including a number from Australia in 1955 and from Nepal in 1972. She constantly strove to clarify the taxonomy of the plants she studied, and this became an essential component of her water-plant field work.
Jessie Bicknell helped establish postgraduate and specialist training for nurses in New Zealand.
Joan Wiffen was a self-taught palaeontologist who greatly advanced knowledge of fossil reptiles in New Zealand. Wiffen, who described herself as ‘a rank amateur, a Hawkes Bay housewife in fact, with no scientific training, just … a great deal of curiosity’, made some of New Zealand’s most important scientific breakthroughs. Despite a lack of formal education or specialised equipment, Joan’s excavations of fossil remains in a remote Hawke’s Bay valley produced the first evidence that dinosaurs had once lived on the New Zealand landmass.
Kathleen Maisey Curtis, who later became Lady Rigg, was an exemplary scientist who specialised in mycology and botany and was a founder of plant pathology in New Zealand.
From the 1940s to the 1960s she advised the public to eat more fruit and vegetables and to cut down on sugar, fat and meat, while continuing her practical efforts to improve food quality. One of her successes was to produce better quality bread. Working with scientists, she educated bakers into using flour made by improved methods of extraction to increase its vitamin B1 content.
Sarah Salmond’s interest in astronomy transcended the boundaries of a mere hobby. In December 1874 several American scientists had come to Queenstown to observe the transit of Venus across the solar disc. Sarah Salmond, convinced that this event should be remembered, lobbied for years to have a plaque erected on the site of the observation.
Nancy Adams was a botanist, botanical artist and museum curator whose significant contributions to botany included the illustrations for more than 40 publications on New Zealand’s native plants, alpine areas, and common trees, shrubs and flowers, and her 1994 work Seaweeds of New Zealand: an illustrated guide.
In 1925 Pérrine wrote New Zealand birds and how to identify them. Although she intended her book for the untrained bird-lover, it influenced scientists as well as lay people and ran to five editions.
During the First World War her strong personality and status as the chairman’s wife enabled her to establish a new kind of women’s leadership. Women’s voluntary work was in demand, and largely by use of the recently installed telephone system she organised Red Cross nursing at Hanmer Springs and supervised emergency measures in the influenza epidemic of November 1918. She was appointed an MBE in 1919. The Red Cross remained a lifelong interest: Thyra headed the Culverden sub-centre for over 50 years and was involved in the local and national organisation during the Second World War. She was made a councillor of honour of the New Zealand Red Cross Society in 1957.
Jamaican physician Dr Cicely Delphine Williams, OM, CMG, FRCP was best known for her discovery of and research into kwashiorkor, a condition of advanced malnutrition, and her work against the use of sweetened condensed milk and other artificial baby milks as substitutes for human breast milk. One of the first women to graduate from Oxford University, Dr Williams was a key figure in advancing the field of maternal and child health in developing nations. In 1948, she became the first director of Mother and Child Health (MCH) at the newly created World Health Organization (WHO).
