Born in 1964 in Gunzenhausen, near Munich (Germany), she grew up in Brazil, where her family moved when she was nine years old, following her father, a geologist. She studied Hispanic History and Philology in Hamburg (Germany), studies that she combined with Business in case one day she would go on to create her own publishing company. She began doing an internship at a German publisher of nature guides and then went on to work for Círculo de Lectores. In 1985 she met her husband, Pedro del Carril, then in charge of the Argentinean publishing house Emecé, founded by Galician exiles in Buenos Aires in 1939. As Emecé Editores España, this Spanish branch of the publishing house had the goal of publishing the best authors from the company’s portfolio and develop a line of fiction according to the tastes of the Spanish market. When Kraus was 28 years old, she left Círculo de Lectores and went to work with her husband at Emecé, and within a short period they managed to establish themselves in the Spanish publishing scene. In 2000, on the occasion of the sale of Emecé Editores to the Planeta group, Pedro del Carril and Sigrid Kraus bought the whole of Emecé Spain and negotiated to keep the books they had had been responsible for since 1992, including the Harry Potter series. In spring 2019 Pedro del Carril and Sigrid Kraus decided to sell their label to the Penguin Random House Group.
