Events prior Tatlock experienced
clinical depression, and was being treated at
Mount Zion. He found her dead, lying on a pile of cushions in the bathroom, with her head submerged in the partly filled bathtub. There was an unsigned
suicide note, which read: Her father found her correspondence and sifted through it, burning letters and photographs in the fireplace. At 5:10 pm he called the Halstead Funeral Home, who contacted the police. The police arrived at 5:30 pm, accompanied by the deputy coroner. At the time of her death she was under surveillance by the
FBI, and her phone had been
tapped, so one of the first people informed about it was FBI director
J. Edgar Hoover, via a
teletype link. The news of her death was reported in Bay Area newspapers. Washburn cabled
Charlotte Serber at Los Alamos. The security chief at Los Alamos, Captain
Peer de Silva, had received the news through the wiretap and Army Intelligence and had broken it to Oppenheimer. Tatlock had introduced Oppenheimer to the poetry of
John Donne, and it is widely believed he named the first
test of a nuclear weapon "
Trinity" in reference to one of Donne's poems, as a tribute to her. In 1962,
Leslie Groves wrote to Oppenheimer about the origin of the name, and elicited this reply:
Inquest A formal inquest in February 1944 returned a verdict of "suicide, motive unknown". In his report, the coroner found that Tatlock had eaten a full meal shortly before her death. She had taken some
barbiturates, but not a fatal dose. Traces of
chloral hydrate were found, a drug normally associated with a "
Mickey Finn" when combined with alcohol, but there was no alcohol in her blood, despite damage to her
pancreas that indicated she was a heavy drinker. As a psychiatrist working in a hospital, she had access to sedatives such as chloral hydrate. The coroner found that she had died at around 4:30 pm on January 4. The cause of death was recorded as "acute
edema of the lungs with pulmonary congestion" — drowning in the bathtub. It seems likely that she knelt over the bathtub, took chloral hydrate, and plunged her head into the water.
Assassination theory There has been speculation by journalists and historians, as well as Tatlock's brother Hugh, that her death was not a
suicide, and the "curious circumstances" The assassination theory has been presented in the drama miniseries
Manhattan.
Cremation Tatlock's father had her remains
cremated. == Portrayals ==
