Adam Bellefeuil was an Vulcan Starfleet officer, who'd gained the rank of admiral by the late 2370s, and taught a mathematics course at Starfleet Academy.

In 2378, between classes, he had a conversation with some of his students on the history of Vulcan warp theory, and the reason for learning Zefram Cochrane's theories.

Circa 2378, he was 176.74 cm tall, and weighed 82.52 kilograms. (TNG video game: Elite Force II)

The reason why his name isn't exactly a traditional "Vulcan" name was not explained in the game. In reality, Adam Bellefeuil is a name of one of the game's developers from Ritual Entertainment.
