Now these are not autographs of Babe Ruth or Mickey Mantle or of presidents or anything like that.
These are the five signatures on my dad's klaf - on his diploma of ordination from Yeshiva University's Rabbi Isaac Elchanan Theological Seminary, which he received in 1942.
The priceless autographs are by five great Torah scholars, Rabbi Binyamin Aronowitz, Rabbi Bernard L. Levinthal of Philadelphia, Rabbi Samuel Belkin, Rabbi Moses Shatzkes (the Lomza Rav) and Rabbi Joseph B. Soloveitchik of Boston (the Rav).
Rabbi Yossi Adler looked at the klaf during the shiva and confirmed what I had been told, that it was rare to have five signatures on such a document. My own ordination has two (Rabbis Belkin and Soloveitchik).
I once asked my dad what it was like to go before these five great rabbis and be examined before receiving semicha - ordination. He told me, "They were tough. They made me sweat."
I greatly treasure this part of the legacy of my dad.
