On this night (of Sep. 5th) in 1920 Jack Pickford and his wife Olive Thomas dined with friends, including actress Mae Murray, in several hot spots in Paris.
They arrived to their hotel at Ritz at about 3 am (On Sep. 6th).
While Jack was asleep, Olive drank Mercury Bichloride, which she mistook for her sleeping medication, in alcohol.
Her screams woke Jack and he rushed to the bathroom, where Olive was at. He called for help and shoved egg whites, butter and milk down her throat to get her to vomit.
When paramedics arrived, they pumped her stomach while Jack held her.
When all failed, she was secretly rushed by ambulance to the American Military Hospital at Neuilly, just outside of Paris.
