H.C. Ørsted suggested, and used itself, about 2,000 new Danish words as subject terms. The two main successes are the words 'oxygen' and 'hydrogen', but there were many more who were not used by anyone other than himself. In the lecture, Ørsted's efforts as a language renew in a historical context: Ørsted was responsible for the natural science breakthrough in the Danish research landscape and his political convictions told ordinary people to be involved; therefore Danish terminology. Then the background to the two significant successes is reviewed – Ørsted had, among other things, been able to take a decision on the basis of the following: Contact with Danish language researcher Rasmus Rask, who advised against the use of the words "oxygen" and "hydrogen". Finally, I contrast the successes with an important failure before Concluding by looking at Ørsted's practice in relation to contemporary language politics.
