Education and career
In 1838, he attended a trade school in Kassel, where he was taught by Robert Wilhelm Bunsen. He studied chemistry from 1845 to 1848 in Marburg, and served as Bunsen's assistant from 1847. In 1848, he earned his doctorate by investigating a red madder dye. He completed his habilitation in 1851 after Bunsen left for Breslau. At the suggestion of Frederick Augustus Genth, Debus was named Bunsen's successor at Marburg.
Later in 1851 he left for England to be a chemistry teacher at Queenwood College followed from 1868 to 1870 by the position as Science Master at Clifton College, Bristol. He then taught at Guy's Hospital, London from 1870 until appointed foundation Professor of Chemistry in 1873 at the new Royal Naval College, Greenwich, where he remained until his retirement and return to Germany.
In 1858, Debus first synthesized imidazole from glyoxal, ammonia, and formaldehyde. The Debus-Radziszewski imidazole synthesis was named after him and Bronisław Leonard Radziszewski  He was elected a Fellow of the Royal Society in 1861.
