She was born Sophie Charlotte Elisabeth Weingarten in 1760, the daughter of an Austrian diplomat, and married Theodor Ursinus, a Prussian privy councillor much older than herself. They lived in Berlin. Those named in the record are a young Dutch officer named Rogay, her husband Theodor Ursinus, and her aunt Christina Witte.
Three deaths were attributed to her. Her lover, a young Dutch officer named Rogay, died in 1797; her husband died in September 1800; and an elderly aunt from whom she inherited died in 1801. All three were recorded as natural at the time: consumption, a stroke, old age.
In 1803 her servant, Benjamin Klein, became violently ill after taking food and medicine from her and survived. He accused her, and arsenic was found in a packet in the house.
She was tried in Berlin and convicted of the attempted murder of Klein. The court did not convict her of any of the three deaths: her husband's body was examined and the finding was equivocal, and the other two were beyond reach. She was sentenced on September 12, 1803 to life imprisonment and held at the fortress of Glatz in Silesia.
Her confinement became notorious for its comfort. She was permitted her own furniture, servants, and visitors, gave coffee parties for the officers of the garrison, and was a fixture of local society for three decades. She was pardoned in 1833 and died at Glatz on April 4, 1836.
The range of one to three is exactly right: one conviction, for an attempt, and three suspected deaths never proved. She is one of the earliest cases in this archive where the count comes from what a court declined to find rather than from what it found.
