The world of science is replete with nouns derived from people. There is the Amp (named after André-Marie Ampère); the Volt (after Alessandro Giuseppe Antonio Anastasio Volta), the Watt (after the Scottish engineer James Watt). And the list goes on. We have the Kelvin, Ohm, Coulomb, Celsius, Hertz, Joule, Sievert. We also have more commonly used nouns in circulation that derive from people. The mackintosh, cardigan and sandwich are perhaps the most frequently used.
