Naja er hats halt entdeckt und es benannt:

French scientist Michel Eugene Chevreul discovered creatine in 1835. Chevreul isolated a component of skeletal muscle - the voluntary muscle we use in exercise - and named it after the Greek work for flesh -Kreas.

He found the presence of muscular creatine was ten times more concentrated in in wild animal muscle than in zoo animal muscles. This observation linked creatine with effective muscular activity - the thought being that a wild tiger, for instance, could be expected to run and jump better than a captive tiger.
entdeckt hatte er es ein Jahr zuvor als Bestandteil von Fleischbrühe
