I was on a plane Monday after attending the memorial service for my friend Sam Graff, who died a few months ago at the age of 86. The mass at Sacred Heart Church was followed by a reception at the Trenton Country Club, not far from where Sam and Sally (my first newspaper editor) lived in a house designed by Sam’s grandfather in 1907. Sam had left the Trenton Times by the time I arrived, working as a photo editor at the New York Daily News. “Photo,” he used to answer the phone, “Graff.”
