Etymology: "Intransient" is a plain formation: the prefix "in-", meaning "not," attached to "transient," which is itself borrowed from Latin "transiens," the present participle of "transire," "to go across" or "pass over." So "transient" originally described something passing through, and "intransient" simply negates that: not passing away, not fleeting, lasting. The prefix "in-" traces back through Latin "in-" to the same ancient root that gives English "un-" and the negating "not" across many Indo-European languages. Its use in English is an ordinary negating prefix, applied here to "transient" with no special history attached. The word is recorded in English as a fresh combination of two existing elements, and its sense of firm, unmoving resistance to change grows naturally from the literal sense of "not passing away." No single coiner or famous first use is documented in the source I have, so the word's story is simply its parts.
