Charles Thomson Rees Wilson, (14 February 1869 – 15 November 1959) was a Scottish physicist and meteorologist who won the Nobel Prize in Physics for his invention of the cloud chamber.Charles Thomson Rees Wilson's biography

Wilson published numerous papers on meteorology and physics, on topics including X-rays, ionization, thundercloud formation, and other meteorological events. Wilson may also have observed a Sprite (lightning), sprite in 1924, 65 years before their official discovery. Weather was a focus of his work throughout his career, from his early observations at Ben Nevis to his final paper, on thunderclouds.
For the invention of the cloud chamber he received the Nobel Prize in Physics in 1927. He shared this prize with the American physicist Arthur Compton, rewarded for his work on the particle nature of radiation. Despite Wilson's great contribution to particle physics, he remained interested in atmospheric physics, specifically atmospheric electricity, for his entire career. For example, his last research paper, published in 1956 when he was in his late eighties (at that time he was the oldest FRS to publish a paper in the Royal Society's journals), was on atmospheric electricity.

Education and early life
Wilson was born in the parish of Glencorse, Midlothian to Annie Clark Harper and John Wilson, a sheep farmer. After his father died in 1873, he moved with his family to Manchester. With financial support from his step-brother he studied biology at Victoria University of Manchester, Owens College, now the University of Manchester, with the intent of becoming a doctor. In 1887, he graduated from the College with a Bachelor of Science, BSc. He won a scholarship to attend Sidney Sussex College, Cambridge, where he became interested in physics and chemistry. In 1892 he received 1st class honours in both parts of the Natural Sciences (Cambridge), Natural Science Tripos.Career
He became particularly interested in meteorology, and in 1893 he began to study clouds and their properties. Beginning in 1894, he worked for some time at the observatory on Ben Nevis, where he made observations of cloud formation. He was particularly fascinated by the appearance of Glory (optical phenomenon), glories. He then tried to reproduce this effect on a smaller scale at the Cavendish Laboratory in Cambridge, expanding humid air within a sealed container. He later experimented with the creation of cloud trails in his chamber by condensation onto ions generated by radioactivity. Several of his cloud chambers survive. Wilson was made Fellow of Sidney Sussex College, and University Lecturer and Demonstrator in 1900. He was known by some as a poor lecturer, due to a pronounced stutter.Contributions
The invention of the cloud chamber was by far Wilson's signature accomplishment, earning him the Nobel Prize for Physics in 1927. The Cavendish laboratory praised him for the creation of "a novel and striking method of investigating the properties of ionized gases". The cloud chamber allowed huge experimental leaps forward in the study of subatomic particles and the field of particle physics, generally. Some have credited Wilson with making the study of particles possible at all.
Wilson published numerous papers on meteorology and physics, on topics including X-rays, ionization, thundercloud formation, and other meteorological events. Wilson may also have observed a Sprite (lightning), sprite in 1924, 65 years before their official discovery. Weather was a focus of his work throughout his career, from his early observations at Ben Nevis to his final paper, on thunderclouds.
Method
Retrospectively, Wilson's experimental method has received some attention from scholars. In a period of scientific inquiry characterized by a divide between "analytical" and "morphological" scientists, Wilson's method of inquiry represented a hybrid. While some scientists believed phenomena should be observed in pure nature, others proposed laboratory-controlled experiments as the premier method for inquiry. Wilson used a combination of methods in his experiments and investigations. Wilson's work "made things visible whose properties had only previously been deduced indirectly". He has been called "almost the last of the great individual experimenters in physics". He used his cloud chamber in various ways to demonstrate the operating principles of things like subatomic particles and X-rays. But his primary interest, and the subject of the bulk of his papers, was meteorology.Awards, honours and legacy
Wilson was elected a List of Fellows of the Royal Society elected in 1900, Fellow of the Royal Society (FRS) in 1900.
For the invention of the cloud chamber he received the Nobel Prize in Physics in 1927.

Personal life
In 1908, Wilson married Jessie Fraser, the daughter of a religious minister, minister from Glasgow. The couple had four children. His family knew him as patient and curious, and fond of taking walks in the hills near his home. He died at his home in Carlops on 15 November 1959, surrounded by his family.References
