The kymograph was invented by Carl Ludwig in 1847.
P. van Bronswijk argues that the kymograph was the first recording device used to record and compare the influence of drug effects. Specifically, the kymograph enabled the study of the influence of drugs on a specific organ, which van Bronswijk says enabled the development of Pharmacology as an independent science in its own right.
