She was the wife and assistant to the Irish physicist John Tyndall. John Tyndall was best known for experiments regarding scattering light by atmospheric particles and the absorption of infrared radiation by gases. [4] She was a key component in John Tyndall's experiments and research and her greatest impacts lie in his work.
In England in 1640, the idea of using mould as a form of medical treatment was recorded by apothecaries such as the botanist John Parkinson, who documented the use of moulds to treat infections in his book on pharmacology. [3] In 17th-century Poland, wet bread was mixed with spider webs (which often contained fungal spores) to treat wounds.
Irish physicist John Tyndall, c. 1885. Later, in 1863, a new rift began to emerge within the scientific community over race theory. Debate was stirred up when the Anthropological Society of London, which rejected Darwinian theory, claimed that slavery was defensible based on the theory of evolution proposed by Darwin.
