Anti-fascist activist and co-founder of the association “Les Dones del 36”. As a child, she left the neighbourhood of Sarrià and went into exile in France. After living through the bombing of Figueres, she crossed the border with her mother in February 1939. Her childhood was spent fleeing from one war and experiencing the ravages of the Second World War. In the 1950s, she returned to Barcelona. During the Transition years, she focused on the recovery of historical memory. Later, with a group of women who survived the Civil War, she co-founded the association “Les Dones del 36”. Of all of them, Piquet was the youngest, which is why they give her the nickname "the girl of 36". They created it in 1997 to highlight the experiences of women who suffered repression or exile during the war in institutes, universities and cultural centres. She collaborated with the Museu d’Història de Catalunya. She also participated in the documentary Amnesia, directed by Dani Lagarto Fernández and Jordi Oriola i Folch. The film narrates the exile of Piquet and that of Milanka Ljubojevic, a refugee from the war in Yugoslavia. For her memory and outreach work, Piquet and other representatives of “Les Dones del 36” were awarded the Barcelona Medal of Honour in 2006.
At the age of five, she went into exile in France with her family, and back in Barcelona, she worked to revive historical memory. She was one of the driving forces behind the association The Women of ‘36.
