Horticulture as a profession for middle-class German and Austrian women, 1890-1940.

Women seeking to work in horticulture in the early twentieth century were the beneficiaries of developments put in motion by the late nineteenth-century women's rights movement. From the 1860s, feminists and social reformers in Europe and America promoted the opening of higher education to women. After success on this front, by 1900, women's advocates pushed for expanding work opportunities suitable for middle-class women, including in horticulture.

The imperative for inclusion: A gender analysis of genetics.

It has now been more than thirty years since Joan Wallach Scott (1986) argued that gender is a legitimate and necessary category of historical analysis that applies to all fields, including genetics. In the intervening years, a substantial body of work has appeared that adds women to the historiography of genetics. While this is a necessary component for including gender as a category of analysis in genetics, it is not sufficient.

Muriel Wheldale Onslow and early biochemical genetics.

Muriel Whedale, a distinguished graduate of Newnham College, Cambridge, was a member of William Bateson's school of genetics at Cambridge University from 1903. Her investigation of flower color inheritance in snapdragons (Antirrhinum), a topic of particular interest to botanists, contributed to establishing Mendelism as a powerful new tool in studying heredity. Her understanding of the genetics of pigment formation led her to do cutting-edge work in biochemistry, culminating in the publication of her landmark work, The Anthocyanin Pigments of Plants (1916).

Opportunities for women in early genetics.

Although women have long been engaged in science, their participation in large numbers was limited until they gained access to higher education in the last decades of the nineteenth century. The rediscovery of Mendel's work in 1900 coincided with the availability of a well trained female scientific workforce, and women entered the new field in significant numbers. Exploring their activities reveals much about the early development of the field that soon revolutionized biology, and about the role of gender in the social organization of science.

The 1909 Darwin celebration. Reexamining evolution in the light of Mendel, mutation, and meiosis.

In June 1909, scientists and dignitaries from 167 different countries gathered in Cambridge to celebrate the hundredth anniversary of Charles Darwin's birth and the fiftieth anniversary of the publication of Origin of Species. The event was one of the most magnificent commemorations in the annals of science. Delegates gathered within the cloisters of Cambridge University not only to honor the "hero" of evolution but also to reassess the underpinnings of Darwinism at a critical juncture.

Thomas Henry Huxley's developmental view of the cell.

In 1853, the British physiologist Thomas Henry Huxley roundly criticized German cell theory. Historians have had difficulty explaining how such a 'progressive' biologist could have rejected cellular autonomy and the central role of the nucleus in cell life. The key to Huxley's thinking is provided by understanding his 'epigenetic' philosophy of biology.
