Evidence Performed by Mary Somerville

  • Name
    Royal Society Experimental Spectroscopy and Photochemical Analysis Project
  • Description

    Seeking to expand her theoretical insights into tangible physical experimentation, Mary designed and executed a series of laboratory trials exploring the intersection of optics, magnetism, and chemistry. Utilizing an optical prism, localized vegetable dyes, and a specialized sample of silver nitrate directly supplied by Michael Faraday, she analyzed the chemical and blackening reactions triggered by concentrated sunlight. Her work resulted in her authoring the experimental paper titled The magnetic properties of the violet rays of the solar spectrum, which was accepted and published in the Philosophical Transactions of the Royal Society in 1826. This project represented the first instance in history of an experimental scientific paper by a woman being published in the journal under her own name, establishing her as an active producer of empirical data rather than a mere consumer of theory.
