A Jewish man who travels to the United States in the 1930s, loses his entire family to the Holocaust, and purchases Ishmael to serve as a strange, surrogate family. Mr. Sokolow is the first to give Ishmael his name, setting in motion Ishmael’s discovery of language and communication. Sokolow teaches Ishmael to speak, and, when Ishmael’s intellect begins to outstrip his own, becomes his research assistant. Mr. Sokolow is Rachel’s father and Grace Sokolow’s husband.
