Sonya Remembers Ruth and Didi Nielsen and the Nielsen House Nielsen House located on the site of the Post Office Parking Lot Across from the Ponds Church Ruth and Didi They were sisters, but you never said….Ruth or Didi…it was always the Ruth and Didi. Ruth committee suicide at 57….four years later Didi died of cancer. Neither married… we could only speculate on why Ruth killed herself. She was a nurse, and she died from an overdose. After Ruth died, Didi was alone, she was teaching math in Butler High., I don’t know why she decided to retire so young, perhaps then you could retire with a pension at that…
