This article introduces the field of terminology, which often considers the Austrian engineer Eugen
Wüster as its founder in the 1930s, although important principles go back in time, in particular to 18th and 19th century botanists, zoologists
and chemists. The contributions of Wüster are presented, as well as the alternative theories, with their criticism of Wüster’s position, which
came to influence the field after 1990. The article further suggests that domain-analytic studies based on epistemological studies of knowledge
domains seems to have been overlooked. The relations between terminology and knowledge organization are addressed, and closer cooperation
between the two fields is called for.
