Jack (20th century)

From Memory Alpha, the free Star Trek reference.

Jack was a teenager who, in 1957, lived in Carbon Creek, Pennsylvania with his mother Maggie. He was very smart and showed interest in astronomy and meditation. Maggie collected money for him in the bar's tip jar, in hope that Jack can get higher education. T'Mir, a Vulcan who was stranded on Earth and lived in Carbon Creek, became friendly with Jack. Jack impressed her with his intellect and curious mind.

When the collections were not enough to send Jack to college, T'Mir intervened and got enough money for Jack to attend college when she sold something from her wrecked ship, to a businessman, that would later be called Velcro. (ENT: "Carbon Creek")

Jack was played by Hank Harris. Some fans speculate that Jack is actually a young Jackson Roykirk.
