Pioneer of Smallpox vaccination

One of the two acts for which she is most famed, is as a pioneer of smallpox vaccination. Her efforts to encourage the use of vaccination has sometimes been referred to as the breakthrough for smallpox vaccination among the public, and though this may be an exaggeration, she is known as an avid supporter of the then very controversial method.^[1]

While baroness Katarina Charlotta Ribbing, the spouse of Charles De Geer, was in reality the first of the Swedish aristocracy to have her children inoculated, it was Catherine Charlotte De la Gardie who, after following the example of Ribbing by having her children vaccinated, became a pioneer by popularizing this method among the peasantry.^[2]

Smallpox vaccination was officially introduced to Sweden in 1756, initially meeting with a great deal of resistance. De la Gardie is regarded as one of the pioneers of smallpox vaccination, as she actively sought to encourage the public to implement it.^[1] The resistance among the peasantry was great, but she managed to convince some parents of the peasantry to vaccinate their children, which allegedly caused a breakthrough in the willingness to use smallpox vaccination among the peasantry.^[3] The children in question has, whether correctly or not, been referred to as the first Swedish children to be vaccinated.^[4]

Prevented a witch trial

The second act for which she is remembered was her successful efforts to stop the last witch trial in Sweden. In 1757, a witch hysteria broke out in the parish of Ål in Dalarna, where thirteen women and five men were accused of abducting children and bringing them to a witches' sabbath. The governor Pehr Ekman ordered their arrest, interrogation and torture.^[5]

De la Gardie became aware of the trial during a trip to Dalarna in 1758. By the help of her connections, she informed the authorities in the capital and thus managed to have the trial stopped. The matter had been treated by the local authorities and church, and when it became known in the country, it was treated as a scandal. While witchcraft trials was formally still legal in Sweden, the law was in practice considered defunct and witch trials a phenomenon of the past: no person had in fact been executed for witchcraft for half a century.^[6] The parliament issued an investigation, the accused were all freed, and Governor Ekman, who had accepted charges of witchcraft and had allowed torture, was sentenced to jail and stripped of his position.

De la Gardie helped the victims of the witch hunt with legal assistance and made sure they were granted compensation from the state, as the torture had made them incapable of work.

For this act, she was nationally hailed as a heroine and was in 1761 awarded a medal by Riddarhuset with the inscription: Catharina Charlotta Taube, comitissa De la Gardie, Fulcrum infelicibus, Ob XII ab injuria servatos cives Ordo R. Equ. 1761.^[4] The Latin inscription on the medal read in translation:

“A source of help to those in need. From the knights and nobility on behalf of twelve female citizens saved from injustice.”^[7]

Love triangle

Catherine Charlotte De la Gardie was a friend of the poet Hedvig Charlotta Nordenflycht, whose most famous poem, Öfver en Hyacint, is a love poem which describes Nordenflycht's love for the young Johan Fischerström. The last poem of Nordenflycht depicts the love triangle between Nordenflycht, Fischerström and Catherine Charlotte De la Gardie, which took place during the winter of 1762/3, when Fischerström was employed as an inspector at the estate of De la Gardie, Sjöö Castle, while Nordenflycht rented a cottage nearby.^[8]

De la Gardie died after having contracted a fatal disease while nursing the sick.
