A woman born in 18th-century Britain was expected to look pretty and keep quiet. At least that’s how we imagine things as we look back at the past from the comfort of our 21st century. But as the European Enlightenment took hold, more and more families provided their daughters with an exceptional education that went beyond what women were expected to know at the time. This was the case in the family of Jane Haldimand, the daughter of a Swiss merchant and banker from Geneva, who had no objection to exposing his only daughter to the same subjects his sons were taught, by the best tutors money could buy.

It so happened that Jane studied Latin and the basic principles of chemistry, biology, history, and philosophy. She also developed an interest in art and learned to draw and sketch. At the age of 15, she was forced to take on the duties of managing the household after her mother died in childbirth. Jane became responsible for raising her younger siblings and hosting her father’s clients, and through conversations with the latter, she managed to further expand her knowledge.

When Jane Haldimand married her husband, he didn’t recoil from her extensive education, quite the opposite. Her husband Alexander Marcet was a client of her father’s. He was a doctor who had studied in Edinburgh after having fled there to escape conflicts that broke out in Geneva in the mid-18th century. Jane accepted her new name – Jane Marcet – by which she’d become well-known in the future. She shared her husband’s hobby, which he preferred over tending to his patients: The couple were simply quite interested in chemistry. The more successful Dr. Alexander Marcet’s clinic became, the more time the two could devote to scientific research. Indeed, Dr. Marcet lectured on chemistry and conducted public demonstrations and experiments, and the couple’s research contributed to medical knowledge and the diagnosis of kidney stones. The two were among the founders of the Royal Society of Medicine, and Alexander played a central role in it.

In the late 18th century, science was in vogue. Dr. Marcet was only one of many popular chemistry lecturers who appeared before the general public and demonstrated the latest scientific innovations. However, this knowledge was generally the domain of men alone and wasn’t considered suitable for women. Jane Marcet didn’t necessarily set out to change this, but she wanted to spread the knowledge she had accumulated over the years in a quick and easy manner, and to make it accessible to women as well. That is how her book Conversations on Chemistry, published in 1805, came about.

It took Marcet about three years to write it, apparently with the help of her husband who edited the chapters. In order to avoid a conflict of interest with her husband’s work, Marcet first published the book anonymously, even though the preface clearly stated that the author was a woman. Marcet also wrote outright that the book was adapted for women and she emphasized that she believed it offered a level of knowledge suitable for ladies. At the same time, she admitted that she was not a scientist and hadn’t delved into the complexities and intricacies of science in a way that others might think wasn’t appropriate for a woman.
As hinted at in the title, the book is structured as a conversation between a teacher and her students, who are referred to by their first names. The teacher explains and demonstrates chemical principles mainly based on the work of the 18th century French chemist Antoine Lavoisier, who laid the foundations for much of modern chemistry. Interspersed throughout are sketches that Marcet herself drew, including some depicting various chemical experiments and devices.

Practically overnight, the book became a smashing success. Sixteen editions were published in Britain alone from 1805 until 1853. Numerous versions and revised or annotated editions of the book were also published in the United States, and imitations were also printed. Marcet herself was involved in updating and revising the additional editions that were published in Britain, and in 1837, her name finally appeared on the cover. The book became the leading chemistry textbook during the first half of the 19th century. A copy of the first edition is kept in the Edelstein Collection at the National Library of Israel, and pictures of it have been included in this article.

Marcet herself continued publishing similar Conversations on… books on subjects like the natural sciences, economy, and theology. But her first published book, Conversations on Chemistry, was the most successful and what she became best-known for. The book’s level of influence can be summed up by the following anecdote: While working as an apprentice in a bookbinding workshop, a young boy came across Marcet’s book. He wasn’t deterred by the fact that its target audience was women; he kept leafing through it and fell in love with the world of chemistry. This boy was from a lower-class family, he wasn’t fortunate enough to receive a formal education, and had to study on his own. Michael Faraday would go on to became one history’s most important chemists and physicists.
