Robert Le Rossignol
Robert Le Rossignol (born April 27, 1884 in Saint Helier , Jersey , † June 26, 1976 ) was an English engineer.
His father was a doctor in Jersey. He attended Victoria College. The states analyst Frederick Woodland Toms aroused his interest in chemistry. From 1901 he studied at University College London in the laboratory of William Ramsay , where he worked with Frederick George Donnan in the field of reaction kinetics . He graduated in 1905 and enrolled in the 1906/07 winter semester as an intern at the TH Karlsruhe . The first two semesters he was Fritz Haber's assistant . Afterwards, when he was paid by BASF, he was officially an intern again. He worked with Haber on the determination of the ammonia balance and the dissociation of carbonic acid.
By analytically determining the reaction products, they were able to approximately determine the equilibrium constant of the ammonia equilibrium. Since little ammonia was formed at normal pressure, the first results were discouraging. Also, the iron catalyst was not effective enough at high pressure. After a few corrective calculations, it emerged that theoretically enough ammonia could be obtained for large-scale production at 600 ° C and a pressure of 200 atmospheres. Since a pressure of this magnitude was not previously used in industry, Le Rossignol built a compressor that could generate such a pressure. The gases circulated in the apparatus under constant pressure. On July 2, 1909, your machine had produced the first 100 cm³ during the demonstration. Rossignol was thus involved in the beginnings of the Haber-Bosch process .
In August 1909 he went to the Auer Society , which Osram had founded. Shortly after the outbreak of World War I, in autumn 1914, he was interned, but released in March 1915 so that he could continue his work.
He returned to England on December 6, 1918, where he worked on electron tubes for the new General Electric Company in the research laboratory at Wembley .
