Thomas Graham FRS FRSE DCL (21 December 1805[1] [2] – 16 September 1869) was a British chemist known for his pioneering work in dialysis and the diffusion of gases. He is regarded as one of the founders of colloid chemistry.[3]
Life [edit]
Graham was born in Glasgow, and educated at the High School of Glasgow. Graham's father was a successful textile manufacturer, and wanted his son to enter into the Church of Scotland. Instead, defying his father's wishes, Graham became a student at the University of Glasgow in 1819. There he developed a strong interest in chemistry, studying under Professor Thomas Thomson, who was impressed and influenced by the young man. He left the University after receiving his MA in 1824.[4]
He later studied medicine at the University of Edinburgh and then briefly taught chemistry at the Glasgow University Portland Street Medical School. In 1828 he was elected an Honorary Fellow of the Royal Society of Edinburgh, his proposer was Edward Turner. He won the Society's Keith Medal for the period 1831–33.[4]
in 1830 he was appointed to be the first professor of chemistry at the Anderson's Medical School, a post later named the Freeland Chair of Chemistry. He also delivered lectures to the Glasgow Mechanics' Institution before moving to take up a professorship at the University of London, where Graham founded the Chemical Society of London in 1841. In 1866, he was elected a foreign member of the Royal Swedish Academy of Sciences.
His final position was the Master of the Mint, where he stayed from 1855 until his death. He was the last person to hold that position.[5]
He died in Gordon Square in London but his body was returned to Glasgow for burial in the family plot at Glasgow Cathedral.[4]

Scientific works [edit]
Thomas Graham is known for his studies on the behaviour of gases, which resulted in his formulation of two relationships, both since becoming known as "Graham's Laws," the first regarding gas diffusion,[6] and the second regarding gas effusion.[7] In the former case, Graham deduced that when measured repeatedly under the same conditions of pressure and temperature, the rate of diffusive mixing of a gas is inversely proportional to the square root of its density, and given the relationship between density and molar mass, also inversely proportional to the square root of its molar mass.[ clarification needed ] [ dubious ] In the same way, in the latter case, regarding effusion of a gas through a pin hole in to a vacuum, Graham deduced that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. These two are sometimes referred to as a combined law (describing both phenomena).
In applied areas, Graham also made fundamental discoveries related to dialysis, a process used in research and industrial settings, as well as in modern health care. Graham's study of colloids resulted in his ability to separate colloids and crystalloids using a so-called "dialyzer", using technology that is a rudimentary forerunner of technology in modern kidney dialysis machines. These studies were foundational in the field known as colloid chemistry, and Graham is credited as one of its founders.[5]
