Sam Zimmerman was not an emotional man — except when it came to opera. He could discourse on Caruso and Callas at length, analyzing the range, the purity of the voice, and the mysterious quality called presence. He passed along that love to his son, Ed, who as an adult discovered something strange: it was a good tool for a corporate lawyer. In honor of Father's Day, Ed remembers his father and the music that kept them together until the end.

→ Is there a piece of music — or a book, movie, or other work of art — that you share with your father?
