During Hitler's rise to power, he and Elsa Lichtmann fled Germany to go to America. He bonded with and became close friends with her throughout their time spent together interned at Ellis Island for 4 years. He was described by Elsa Lichtmann as "The only man who loved me without putting his hands on me!" The game never makes clear whether this is an indication of the man's orientation, or whether he considered her like a sister; they were certainly close enough that he named Lichtmann the beneficiary of his life insurance policy, indicating that, at the time of his death, she was his only significant other.
Events of L.A. Noire
Harlan Fontaine found a job for him with Elysian Fields Development. However, while working on one of Elysian Fields' substandard houses, the poor roofing material collapsed on him, and he died as a result of his injuries. Buchwalter's insurance named Elsa as the primary beneficiary. To cover up the true reasons for Lou's death (the shoddy work materials for the building of the housing developments), the insurance payout was substantially increased by Elysian Fields to $20,000. The large amount of money caused Cole Phelps to persuade Elsa to go to Jack Kelso for help, telling her to say she suspected foul play, and ultimately to ask Kelso for help in uncovering and putting an end to the conspiracy behind Elysian fields development and the Suburban Redevelopment Fund.
