Alonis Cobaryn

Memory Beta, the wiki for licensed Star Trek content.

Alonis Cobaryn was one of the first captains to serve in the Federation Starfleet. Amongst the earliest captains, there was a divide between those considered "Butterfly Catchers", (Scientists) and Romulan War veterans, over what the future of the new Starfleet would be.

Cobaryn was on the butterfly catcher's side. He was a Rigellian, and was made captain-- first of an old Christopher ship, and later of the Daedalus-class USS Horizon. (Star Trek novel: Starfleet: Year One)

He is presumed to have still been in command when the ship made contact with the inhabitants of Sigma Iotia II; he left behind a book, which had been a gift to him - "Chicago Mobs of the Twenties". This action contaminated the culture of the Sigma Iotians, who modelled their society after the Chicago Mobs. (TOS episode: "A Piece of the Action")
