Yahrtzeit of Rabbi Joshua Isaac Shapira, a leader of 19th century European Jewry known by the nickname Reb Eisele Charif. The story is told that when his daughter was ready to get married, Reb Eisel sought out the top yeshiva student. He entered the study hall and announced: "I have a very difficult question on a passage in the Talmud. Whoever can supply the correct answer will have my daughter's hand in marriage." Soon a long line formed, and one by one the students tried to provide the answer. And one by one, Reb Eisel explained how the answers were incorrect. This went on for days, but when no one came up with the correct answer, Reb Eisel packed up and left. He had just reached the edge of the city, when he heard a voice shouting after him: "Reb Eisel, Reb Eisel!" He turned around to see a young man running in his direction. The student explained: "I know I wasn't able to satisfy the condition for marriage, but just for my own sake, could you please tell me the correct answer?" "Aha!" shouted Reb Eisel. "If you have such a desire to know the truth, then you will be my son-in-law!"
