In the 19th century, four men, after discovering their shared passion for scientific progress at Cambridge University, decided to meet on Sunday mornings to discuss the state of science in Great Britain and around the world. Inspired by the great politician and scientific reformer Francis Bacon, the members of the Philosophical Breakfast Club joined forces to promote a new scientific revolution. William Whewell, Charles Babbage, John Herschel, and Richard Jones, prestigious researchers who made important discoveries in various fields, were the last natural philosophers, who not only stood at the forefront of the modernization of science but also gave birth to a new species: the scientist. In this dazzling essay, historian Laura J. Snyder explores the political and religious motivations, the friendships and enmities, and the thirst for knowledge and power that drove these extraordinary men, protagonists of a true intellectual revolution.
