Biography
Hélène Tronchin was born on 15 May 1828 in Geneva, the daughter of Colonel Armand Henri Louis Jacob Tronchin, a military officer and lay president of the Evangelical Society of Geneva. She grew up at Les Délices, her family's mansion that had previously been the home of Voltaire.

In 1848, she married the Swiss nobleman Charles Wolfgang de Gingins, Seigneur de Gingins. Her husband's family owned La Sarraz Castle. De Gingins became a salonnière, hosting political and religious salons in her home in Geneva. Through her salons, she was introduced to the English social reformer Josephine Butler, who convinced her to join the Comité intercantonal de dames in 1876. Through this organization, de Gingins worked to end female prostitution and promote children's welfare. Later, she joined the Association of Friends of the Young Girl and l'Association du sou pour le relèvement moral, which financed relief work. From 1891 to 1905, she served as vice president of the International Abolitionist Federation.
