Commander Jack Keller who is a Human Male who lives in the 24th century and services the United Federation of Planets, Starfleet and services onboard the battle cruiser USS Valiant (NCC-1707) under the command of Lieutenant Colonel William Tyson as the executive officer. (Star Trek: Valiant)

Childhood
Keller was born in Baltimore, Maryland in 2346. During his young age he was close friends with Kelly Saunders. They had a close bond, and at some point during high school they thought about changing their relationship to one more intimate. But in the end they both agreed it might ruin their friend ship.

Academy years
Keller and Saunders both applied for the Academy and were accepted together. During his academy years he met and dated Janice Pelar, a junior cadet from Betazed. They were both leading towards majors and careers in science. Pelar broke off their relationship when Keller's career plans shifted to that of command. One of Keller's favorite instructors was then Commander Victor Mandrake, who went on to become Captain of the USS Vulture (NCC-14330) during the Dominion War. In 2380, Mandrake attempted to takeover the USS Pioneer (NCC-1084) from Captain Benjamin Kelsoe and his crew. He was unsuccessful and was court martialed. This was heartbreaking to Keller, who had idealized Mandrake.

Starfleet years
Between 2377 and 2382, Keller had served as the executive officer of the USS Dallas (NCC-2019).
