This is a timeline of women in science, spanning from ancient history up to the 21st century. While the timeline primarily focuses on women involved with natural sciences such as astronomy, biology, chemistry and physics, it also includes women from the social sciences (e.g. sociology, psychology) and the formal sciences (e.g. mathematics, computer science), as well as notable science educators and medical scientists. The chronological events listed in the timeline relate to both scientific achievements and gender equality within the sciences.

Ancient history

Italian physicist Laura Bassi

French polymath Émilie du Châtelet

Swedish agronomist Eva Ekeblad

Her contributions to systemic cryptogamic studies were formally recognized by Prussian emperor Friedrich Wilhelm III, and Libert received a gold medal of merit.
• 1832: French marine biologist Jeanne Villepreux-Power invented the first glass aquarium, using it to assist in her scientific observations of Argonauta argo.
• 1833: English phycologists Amelia Griffiths and Mary Wyatt published two books on local British seaweeds.

• 1833 Orra White Hitchcock (March 8, 1796 – May 26, 1863) was one of America's earliest women botanical and scientific illustrators and artists, best known for illustrating the scientific works of her husband, geologist Edward Hitchcock (1793–1864), but also notable for her own artistic and scientific work. The most well known appear in her husband's seminal works, the 1833 Report on the Geology, Mineralogy, Botany, and Zoology of Massachusetts and its successor, the 1841 Final Report produced when he was State Geologist. For the 1833 edition, Pendleton's Lithography (Boston) lithographed nine of Hitchcock's Connecticut River Valley drawings and printed them as plates for the work. In 1841, B. W. Thayer and Co., Lithographers (Boston) printed revised lithographs and an additional plate. The hand-colored plate "Autumnal Scenery. View in Amherst" is Hitchcock's most frequently seen work.
• 1835: Scottish polymath Mary Somerville and German astronomer Caroline Herschel were elected the first female members of the Royal Astronomical Society.
• 1836: Early English geologist and paleontologist Etheldred Benett, known for her extensive collection of several thousand fossils, was appointed a member of the Imperial Natural History Society of Moscow. The society – which only admitted men at the time – initially mistook Benett for a man due to her reputation as a scientist and her unusual first name, addressing her diploma of admission to "Dominum" (Master) Benett.
• 1840: Scottish fossil collector and illustrator Lady Eliza Maria Gordon-Cumming invited geologists Louis Agassiz, William Buckland and Roderick Murchison to examine her collection of fish fossils. Agassiz confirmed several of Gordon-Cumming's discoveries as new species.
• 1843: During a nine-month period in 1842–43, English mathematician Ada Lovelace translated Luigi Menabrea's article on Charles Babbage's newest proposed machine, the Analytical Engine. With the article, she appended a set of notes. Her notes were labelled alphabetically from A to G. In note G, she describes an algorithm for the Analytical Engine to compute Bernoulli numbers. It is considered the first published algorithm ever specifically tailored for implementation on a computer, and Ada Lovelace has often been cited as the first computer programmer for this reason. The engine was never completed, so her program was never tested.
• 1843: British botanist and pioneering photographer Anna Atkins self-published her book Photographs of British Algae, illustrating the work with cyanotypes. Her book was the first book on any subject to be illustrated by photographs.
• 1846: British zoologist Anna Thynne built the first stable, self-sustaining marine aquarium.

• 1904: American geographer, geologist and educator Zonia Baber published her article "The Scope of Geography", in which she laid out her educational theories on the teaching of geography. She argued that students required a more interdisciplinary, experiential approach to learning geography: instead of a reliance on textbooks, students needed field-trips, lab work and map-making knowledge. Baber's educational ideas transformed the way schools taught geography.
• 1904: British chemists Ida Smedley, Ida Freund and Martha Whiteley organized a petition asking the Chemical Society to admit women as Fellows. A total of 19 female chemists became signatories, but their petition was denied by the society.

Her curation system of keeping type specimens separate from other collections – unconventional at the time – allowed her to quickly find and retrieve the specimens.
• 1906: Russian chemist Irma Goldberg published a paper on two newly-discovered chemical reactions involving the presence of copper and the creation of a nitrogen-carbon bond to an aromatic halide. These reactions were subsequently named the Goldberg reaction and the Jourdan-Ullman-Goldberg reaction.
