Samuels was born in 2327 in Bergen, Norway on Earth. He moved to the Federation colony on Volan II in 2350, where he was a farmer. He married a woman named Louise and had two daughters, born in 2356 and 2358.
After the Federation-Cardassian Treaty in 2370, like the other colonists he was given the choice of relocating or accepting Cardassian rule. He stayed, and risked the treatment of the Cardassian authorities. Samuels joined the Maquis in order to defend his home from Cardassian encroachment. When it was suspected that the Cardassian freighter Bok'Nor was smuggling weapons into the Demilitarized Zone, he joined a plot to destroy the ship. Traveling to Deep Space 9, he disguised himself as a Starfleet crewman and planted a protomatter implosion device on the ship. Following this act, Samuels met with fellow member Sakonna, who arranged for quarters for him. However, he was then captured by a Peliar Zel couple for the Cardassians and subsequently interrogated by Gul Evek. Samuels made a full confession during the interrogation, presumably under duress, and later "committed suicide" in his cell. (DS9: "The Maquis, Part I")
