Susan Cain's grandfather
She also gives a couple of clues to her family by identifying her father as "a dedicated physician" and the size of her family, which included one sister and one brother. So these were what I had to go on to make the connection. Well, actually my husband took over the Google search when he arrived at http://www.nytimes.com/2000/04/18/nyregion/rabbi-israel-schorr-94-led-brooklyn-synagogue.html
Everything fits with Rabbi Israel Schorr. He died at 94 in the month of April of the year 2000 after serving as " rabbi of Congregation Beth El and then, after a merger, of Congregation Beth El-Young Israel for 62 years." The family details match, as well: "He was predeceased by his wife, Bertha. He is survived by his daughter, Gail Horowitz of Lawrence, N.Y, and three grandchildren." Another source reveals that Gail Horowitz is married to Dr. Lawrence Horowtiz, the doctor father of 3 identified in the description. It's possible to dig up even more information if one wants to pay for it. But what I was really after was the name of the grandfather.
