"August Wilhelm von Hofmann (8 April 1818 – 5 May 1892 ) was a German chemist who made considerable contributions to organic chemistry. His research on aniline helped lay the basis of the aniline-dye industry, and his research on coal tar laid the groundwork for his student Charles Mansfield's practical methods for extracting benzene and toluene and converting them into nitro compounds and " - Hofmann chemistry
