David "Legal" Siegel (b. 1932) is a resident of Menorah Manor in Los Angeles, and a former law partner of J. Michael Haller. He is the father of two sons. He is described as a brilliant legal strategist. He reportedly sent the younger Haller to law school after his father died, but it is not clear what this means. Did he simply help him gain admission or did he help pay for his education? In any case, Haller views Siegel as a substitute father. Haller would often visit Siegel and bring him food that he was not supposed to have in Menorah Manor, such as a French Dip sandwich from Phillipe the Original.
