Marie Stopes

Marie Stopes is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Marie Stopes rather than just read about it. In short: Marie Charlotte Carmichael Stopes (15 October 1880 – 2 October 1958) was a British author, palaeobotanist and campaigner for eugenics and women's rights. She made significant contributions to plant palaeontology and coal classification, and was the first female academic on the faculty of the University of Manchester.

Key takeaways

  • Marie Stopes belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Marie Stopes to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Marie Stopes from memory before moving on to harder problems.

Reference excerpt

Marie Charlotte Carmichael Stopes (15 October 1880 – 2 October 1958) was a British author, palaeobotanist and campaigner for eugenics and women's rights. She made significant contributions to plant palaeontology and coal classification, and was the first female academic on the faculty of the University of Manchester. With her second husband, Humphrey Verdon Roe, Stopes founded the first birth control clinic in Britain, which bore her name for much of its 100-year history. Stopes edited the newsletter Birth Control News, which gave explicit practical advice. Her sex manual Married Love (1918) was controversial and influential, and brought the subject of birth control into wide public discourse. Stopes publicly opposed abortion, arguing that the prevention of conception was all that was needed, though her actions in private were at odds with her public pronouncements.

Early life and education Stopes was born in Edinburgh. Her father, Henry Stopes, was a brewer, engineer, architect and palaeontologist from Colchester. Her mother was Charlotte Carmichael Stopes, a Shakespearean scholar and women's rights campaigner from Edinburgh. At six weeks old, her parents took Stopes from Scotland; the family stayed briefly in Colchester then moved to London, where in 1880 her father bought 28 Cintra Park in Upper Norwood. Both of her parents were members of the British Association for the Advancement of Science, where they had met. At an early age, she was exposed to science and was taken to meetings where she met the famous scholars of the day. At first, she was home-schooled, but from 1892 to 1894 she attended St George's School for Girls in Edinburgh. Stopes was later sent to the North London Collegiate School, where she was a close friend of Olga Fröbe-Kapteyn. One of her teachers Clotilde von Wyss was very fond of her. Stopes primarily focused on her science career in her 20s and 30s. Stopes attended the University of London in 1900, at University College London as a scholarship student, where she studied botany and geology; she graduated with a first class B.Sc. in 1902 after only two years by attending both day and night schools at Birkbeck, University of London. Stopes's father died in 1902 leaving her family in financial ruin. Her palaeobotany professor, Francis Oliver, took her under his wing and hired her as his research assistant in early 1903. This is what sparked her interest in palaeobotany, building a platform to begin her career. Oliver was on the verge of debatably one of the greatest finds in palaeobotany when he took Stopes on as a research assistant. Initially, it was thought that most of the fossil plants found in Carboniferous Coal Measures were ferns, Stopes was tasked to find the specimens that showed better connection with the seeds of fern fronds. It was discovered that some of the "ferns" bore seeds. "Seed ferns" became known and recognized as the missing link between ferns and conifers. They later became known as the pteridosperm. She was provided the opportunity to work with the world's leading experts in palaeobotany at the time. Within the same year she won the Gilchrist scholarship from University College London, with the help of Oliver and her geology professor, Edmund Garwood who provided incredible references. Following this, Stopes earned a D.Sc. degree from University College London, becoming the youngest person in Britain to have done so. In 1903 she published a study of the botany of the recently dried-up Ebbsfleet River. After carrying out research on Carboniferous plants at the Royal Botanic Gardens, Kew, and at University College London, she put the money she received from the Gilchrist Scholarship towards a year's worth of funding her study on the reproduction of living cycads at the Ludwig-Maximilians-Universität München. There, she worked with Karl Goebel, who was a leading palaeobotanist on cycads. Stopes used this study as her doctoral dissertation, she presented her dissertation in German and received a PhD in botany in 1904. She was, in 1904, one of the first women to be elected a fellow of the Linnean Society of London, and was appointed a demonstrator in order to teach students. She was also a fellow and occasional lecturer in palaeobotany at University College London until 1920.

Worked examples

Example 1 — a first encounter with Marie Stopes

Start with the simplest possible case. Write down what Marie Stopes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Marie Stopes before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Marie Stopes ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Marie Stopes

In research
Marie Stopes appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Marie Stopes in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Marie Stopes is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1880 births, 1958 deaths, 20th-century British botanists, so understanding it makes those chapters shorter.
In everyday life
Look for Marie Stopes outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
