Mr. Nagel said his wife was particularly attuned to her own appearance.

“It was a matter of great attention,” he said. “She thought it was an art.”

She believed, Mr. Nagel added, that people should be concerned with how they look from all angles: “She thought you should always use the double mirror before you leave the house.”
