Fred William Oesterreich (Dec 8, 1877 - Aug 22, 1922) was a wealthy textile manufacturer married to "Dolly" Oesterreich (b. Walburga Korschel June 12, 1880 in Chicago, Illinois – April 8, 1961 in Los Angeles), an American housewife. Dolly gained notoriety for her bizarre 10-year affair with Otto Sanhuber (aka, Otto Weir; aka, Walter Klein, Jul 16, 1888 - ?) which culminated in the shooting death of her husband.
Dolly and Fred
The story inspired the feature film The Bliss of Mrs. Blossom as well as the made-for-TV movie The Man in the Attic, with Neil Patrick Harris, and was also the subject of Investigation Discovery's series A Crime to Remember in 2017 (Season 4 Episode 6, "Guess Who?").
Dolly Oesterreich, 33 at the time, first became friendly with 17-year-old Otto Sanhuber (Jul 16, 1888 - ?)  around 1913 and described him as her "vagabond half-brother." The two quickly became lovers and met clandestinely at Sanhuber's boarding room or at a nearby hotel. They also arranged trysts at Dolly's Milwaukee, Wisconsin home but, when neighbors began noting Otto's increasingly frequent comings and goings and alerted her husband, Dolly suggested to Otto that he quit his job and secretly move into the Oesterreichs' upstairs attic to allay any further suspicions. He readily agreed to the arrangement. Not only would this put him in closer proximity to his lover but it would also give him time to pursue his dream of writing pulp fiction stories. Sanhuber would later describe himself as Dolly's "sex slave."
Dolly's husband Fred remained unaware of the new "boarder," though on several occasions he came close to discovering the deception. When the Oesterreichs moved to Los Angeles in 1918, Dolly had already sent Sanhuber to await their arrival. Dolly deliberately chose a new house with an attic (somewhat of a rarity in Los Angeles), and once again Otto moved in to resume their affair.

Then and Now
Sanhuber remained at large for eight years, eventually moving to Canada, changing his name to Walter Klein and marrying another woman before returning to Los Angeles.
In 1930, after a falling out, Dolly's personal attorney (and current lover) Herman Shapiro revealed to police what he knew about Otto Sanhuber's involvement in the murder. Sanhuber was arrested and convicted of manslaughter but later released because the statute of limitations had expired.
Fred William Oesterreich is interred in the Great Mausoleum at Forest Lawn Glendale Cemetery.
Walburga “Dolly” Oesterreich is interred at Holy Cross Cemetery in Culver City, California.
