Many scientific units are named after scientists, for example Tesla for magnetic flux, Farad for capacitance and Newtons for force.
When did the tradition of naming scientific units begin?

In 1861, Charles Bright and Latimer Clark proposed the names of ohm, volt, and farad in honour of Georg Ohm, Alessandro Volta and Michael Faraday respectively for the practical units based on the centimetre-gramme-second absolute system. This was supported by Thomson (Lord Kelvin). These names were later scaled for use in the Practical System. The concept of naming units of measure after noteworthy scientists was subsequently used for other units.
