Industrial research chemist Bettye Washington Greene was an early African American pioneer in science. She was the first African American female Ph.D. chemist to work in a professional position at the Dow Chemical Company, where she researched latex and polymers.
Scientist and environmentalist Louise Crossley (1942 – 30 July 2015) was closely involved in the establishment of the Tasmanian Greens and the Global Greens.
Elsa Beatrice Kidson became a world leader in the research into magnesium deficiency in apples, and did extensive work on the vitamin C content of fruits, the relationship between calcium deficiency and the disease bitter pit in apples, and the link between mineral constituents and nutritional diseases in tomatoes. Her research was of fundamental significance to horticulture and, especially, to the fruit-growing Nelson region.
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.
