No, he wasn't.

Knowing what we do now, the quest itself has Ballas telling us how infecting "the best and brightest" were how they made all the original warframes. Eslewhere in the game, there are a ton of examples of the warframes that were originally people, Limbo was a mathamatician and Mirage was a dancer/performer before they were transformed, but they did die before the game takes place (Mirage fighting the infested and Limbo dying by trying to leap too far into the rift). Rhino's umbral version, however, is mentioned (in rhino primes codex entry), going on a rampage and killing everyone in an orokin lab. It was through this rampage though that the oroking learned that the Tenno COULD calm down the warframes. His fate is never revealed, however, making him a very likely candidate for being another Umbra variant.
