Which came first, the words or the dictionary?

Putting it into the context of this NG, in which dictionary
did the word, "transistor" appear before it was used by

3 The definition of a dictionary:
A book dealing with the individual words of a language (or certain
specified classes of them), so as to set forth their orthography,
pronunciation, signification, and use, their synonyms, derivation,
and history, or at least some of these facts. (O.E.D.)
History in this context relates to the historic derivation of the word.
Yet
again a matter of record, again the facts speak for themselves.
