Question: What is the date of death of Ernest Gottlieb Sihler's father?
Sentence (from "Ernest Gottlieb Sihler"): Not long after leaving Concordia College in Milwaukee, Wisconsin, for the post at New York University, he endowed a library fund there for the purchase of "books of standard value" (i.e., presumably excluding rare books, incunabula, and so on).
Relevant evidence: No
