Robert H. Whytlaw-Gray (1877 – 1958) was a chemist, born in London, England. He studied at University of Glasgow and University College London. He and William Ramsay isolated radon and studied its physical properties (density, weight).[1]
After attending St Paul's School, Gray studied at the University of Glasgow and at University College London. During his time at Glasgow, he was injured in an explosion during an attempt at diazotisation, and, after being found by Morris Travers, needed to be treated in hospital. He studied at the University of Bonn and was awarded his PhD in 1906.[1] He then returned to University College London and worked on the characterisation of radon with William Ramsay, with whom he succeeded in isolating it in 1910,[2] and Frederick Soddy. From 1914 to 1923, he taught at Eton College, and then became professor of inorganic chemistry at the University of Leeds. In 1928, he was elected Fellow of the Royal Society. He retired in 1950, and died in 1958 in Welwyn.[1]
