Archduke Ludwig Salvator never married. When he was young he fell in love with a cousin, Archduchess Mathilde, the daughter of the Duke of Teschen. Ludwig wanted to marry her, but she was promised to Prince Umberto of Savoy. On June 6, 1867, Mathilde, then only 18, was getting dressed to attend the theatre. She enjoyed smoking cigarettes, but when her father, who abhorred smoking appeared, she tried to hide the cigarette behind her. Her dress caught fire, and she died in front of her family, sustaining second and third-degree burns. Relationships with women included Catalina Homar. She convinced Ludwig to let her visit Jerusalem and it is believed that it was there that she contracted the leprosy that took her life in 1905.
