Sounds to me like Anna Hindman had good cause for wanting to divorce her husband, namely a) his belief that 4 hours sleep is all anyone needs, and b) wiring her bed to shock her every 4 hours to prevent her from sleeping longer than that.
But according to the news reports, she eventually forgave him and withdrew her divorce petition — after he got rid of the "shocking machine." And it sounds like they remained married for the rest of their lives... if the Anna Hindman in this obituary is the same person (which it must be, because all the names/dates match up).
Anna Louise Hindman, 74, of Rogersville passed away Thursday, September 13, 2012 in Springfield. Anna was born on July 8, 1938 in Springfield to Eulan and Olive (Turner) Bussard. She was married to Michael J. Hindman on July 17, 1953 and he preceded her in death on December 15, 2004. She was an accomplished roller skater, both figure and racing and performed for President Truman. She had her pilots license and enjoyed flying and riding motorcycles with her husband.
