[2] Born in New York, but later raised in Rome, Italy, Montaigne spoke several languages - a skill he used to his advantage in securing roles in international productions.

He served in the U.S. Marine Corps[3] and was only one platoon apart in the Parris Island boot camp from his future friend and co-star Steve McQueen.

[1] A year later, he portrayed the Vulcan Stonn, the paramour of Spock's intended bride T'Pring, in the episode "Amok Time"—a role that he reprised in 2006 in the unofficial mini-series Star Trek: Of Gods and Men.

Additionally, he guest-starred on episodes of Batman, Voyage to the Bottom of the Sea, The Man From U.N.C.L.E., Blue Light, Mission: Impossible, The Time Tunnel, The Invaders, Perry Mason, McCloud, Hogan's Heroes, Bonanza and The Feather and Father Gang.

[citation needed] In 2007, Montaigne voiced a guest-starring role in the pilot episode of the web series Star Trek: The Continuing Mission.
