William A. Tilden

Sir William Augustus Tilden, FRS ( born August 15, 1842 in London, † December 11, 1926 ) was a British chemist in the field of organic chemistry.

Life

After schooling, he made training for pharmacists and then spent a year studying at the Royal College of Chemistry, before he worked as a projectionist at the Pharmaceutical Society 1863-1872. In 1872 he was a lecturer in chemistry at Clifton College in Bristol and then took in 1880 a reputation as Chair of Chemistry at the Mason College at. Also in 1880 he became a Fellow of the Royal Society.

In 1894, he was the successor of Thomas Edward Thorpe Professor of Chemistry at the Royal College of Science in South Kensington.

During his tenure there, he proved that there is only one combination of nitric oxide and chlorine with nitrosyl chloride and this is a valuable reagent for the study of terpenes. He discovered, moreover, that in the case of the production of hydrocarbon -isoprene from terpenes, this separated into fragments whose properties are identical to those of natural rubber.

He also discovered that changes specific heat with temperature. This results in the decrease of the specific heat capacity, when the temperature drops and to increase when the temperature rises, the amount of displacement is in inverse proportion to the atomic weight of the element. This discovery was of great importance for numerous industries.

In addition, he was from 1903 to 1905 not only President of the Chemical Society, but between 1904 and 1906 also Vice- President of the Royal Society.

Tilden was in 1908 awarded the highest British award for scientists in the field of chemistry because of its chemical discoveries, especially in the heat capacity and the terpenes, the Davy Medal of the Royal Society.

In 1909 he was knighted ( Knight) and henceforth led the noble title "Sir".
