History of biochemistry
The term “biochemistry” itself is derived from the combining form "bio-", meaning "life", and "chemistry". The word is first recorded in English in 1848, while in 1877, Felix Hoppe-Seyler used the term ("Biochemie" in German) in the foreword to the first issue of "Zeitschrift für Physiologische Chemie" (Journal of Physiological Chemistry) as a synonym for physiological chemistry and argued for the setting up of institutes dedicate to its studies. Nevertheless, several sources cite German chemist Carl Neuberg as having coined the term for the new discipline in 1903, and some credit it to Franz Hofmeister.
Chemotherapy
The word "chemotherapy" without a modifier usually refers to cancer treatment, but its historical meaning was broader. The term was coined in the early 1900s by Paul Ehrlich as meaning any use of chemicals to treat any disease ("chemo-" + "-therapy"), such as the use of antibiotics ("antibacterial chemotherapy"). Ehrlich was not optimistic that effective chemotherapy drugs would be found for the treatment of cancer. The first modern chemotherapeutic agent was arsphenamine, an arsenic compound discovered in 1907 and used to treat syphilis. This was later followed by sulfonamides (sulfa drugs) and penicillin. In today's usage, the sense "any treatment of disease with drugs" is often expressed with the word "pharmacotherapy".
