John emailed me a few days ago with new information he dug up; Marie Betelle’s obituary from the New York Times:
August 30, 1959
Mrs. Marie Ann Louise Betelle, widow of James O. Betelle, an architect, died of a brain hemorrhage early yesterday at University Hospital. She was 52 years old.
Mrs. Betelle lived at 450 East 61st Street. She had a collection of objects d’ art, fine linens, engraved stemware, and religious articles.
There are no known survivors.
So, Mrs. Betelle was 47 when JOB died in 1954, at 75. That made her quite a few years younger than him, on the order of twenty-eight years. It’s good to be an architect!
That address, 450 East 61st Street, is in the area of a collection of hi-rise apartments and small old industrial buildings, right next to the 59th Street Bridge, so it’s not likely her residence is still standing (though I will go by there to make sure).
