In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, now known as carbolic acid, which he derived in an impure form from coal tar.

Name-letter effect once according to estimated letter frequency. Subjects indeed significantly overestimated the frequency of letters in their names, although there was no significant positive correlation between the overestimation of frequency and the name-letter effect. The researchers also asked subjects to rate how much they liked their own name. Subjects who liked their name had a stronger name-letter effect than those who did not like their name, but they did not overestimate the frequency of own-name letters more than subjects who did not like their names. Hoorens and Nuttin concluded that there is no support for the subjective frequency hypothesis. Evaluative conditioning
