- “Oh, Sammy, maybe we never should have come to this place…”
- ― Mariska Lutz[src]
Samuel, along with Mariska, is of Jewish origin.
Sam was a native of Colorado in the United States and was enlisted in the U.S. army during World War II. He met Mariska when he was stationed in Eastern Europe after the war. He and Mariska wanted to get married, but circumstances made it difficult for them to emigrate back to the United States together. In 1948 they were contacted by one of Andrew Ryan's recruiters who offered them jobs in construction of the Atlantic Express railway in Rapture. Sam quickly accepted, seeing this as an opportunity to get out of his tour of duty in the army.
After construction of the railway was completed, Sam was laid off like many other workers, and he discovered that the offer to come to Rapture had been a one way ticket; he and his family would not be allowed to leave. The Lutzs ended up living with nine other families in the crowded number six suite of Artemis Suites, unable to afford housing in even the cheapest rooms of the Sinclair Deluxe. Sam continued to accept temporary jobs, such as maintenance on the bathysphere in the Lighthouse, but he couldn't make enough money to raise his family out of poverty. Sam finally moved his family to a room in The Fighting McDonagh's Tavern after a fight between Splicers in suite six ended with two people dead.
Samuel is mentioned in several of Mariska's audio diaries, referred to affectionately as "Sam" or "Sammy". After the Rapture Civil War began, the Lutzs' daughter Masha was kidnapped and turned into a Little Sister. When faced with the sight of Masha drawing blood out of a corpse by Fontaine Fisheries, Sam pointed her out to his wife who initially refused to believe it. This realization led both he and Mariska to commit suicide by overdosing on pills in their room within the Fighting McDonagh's Tavern in Neptune's Bounty. Their bodies can be found there during the events of BioShock.
