He was quiet, mild-mannered, and thoughtful. (Picture a cross between Albert Einstein and Captain Kangaroo and you've got the idea.) He had a fine speaking voice, and his reading voice was magnificent. He enjoyed reading aloud, works of literature or news articles on the events of the day.
In his last years, I believe he worked as a volunteer reader for Books On Tape or some similar program, recording books for the blind. He also became involved in the synagogue choir (he attended a Conservative congregation) which brought him much joy until his health prevented him from continuing.
I like to think I've inherited my father's disposition and his love of the spoken word. Sometimes I read aloud to myself, and whenever I do, I think of him.
