Jeanne Villepreux-Power (1794-1871) was a contemporary of the great Scottish mathematician and science populariser Mary Somerville and Nancy Maria Donaldson Johnson, who obtained the first patent in the United States in 1843 for her hand-operated ice-cream machine.
Jeanne produced exquisite illustrations of the species she studied and the observations she made about them, as did other scientists such as Marya Sybilla de Meriam (1647-1717), an entomologist who illustrated and demonstrated the development of metamorphosis in insects, and Eleanor Ormerod (1828-1901), whose drawings helped farmers and ranchers to identify harmful insects and the effects they produced.
Throughout history, the field of biology and natural sciences has been plagued by women researchers, such as Hildegard of Bingen (1098-1179), who was one of the most versatile and influential women of the Middle Ages in 12th century Western Europe. Mystic, abbess, theologian, writer of scientific books on plants and minerals and their healing powers, as well as on the workings of the human body, anatomy teacher Anna Morandi Manzolini (1716-1774). Laura Bassi (1711-1778) who fostered the constitution of a network of experimenters that connected Italy with the scientific culture of France and England.
Since the end of the 19th century there have been many women dedicated to science, such as Marie Curie (1867-1934), a pioneer in the study of radioactivity, with two Nobel Prizes, one in physics and the other in chemistry, Rachel Carson (1907-1964), a marine biologist, zoologist and writer, Rosalind Elsie Franklin (1920-1958) British chemist and crystallographer whose work was fundamental to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, carbon and graphite.
