Margarita Guerrero was an Argentinean[1] dancer and writer. She is known for her collaborations with Jorge Luis Borges, with whom she co-wrote and edited Book of Imaginary Beings and El "Martín Fierro".[2][3][4] As his eyesight failed, Borges relied increasingly on collaborators in creating his work, and Guerrero's role in Book of Imaginary Beings in particular is thought to have been that of a researcher and compiler.[1]
Borges dedicated Other Inquisitions, 1937–1952 to her under the name "Margot Guerrero".[5]
She was interested in the occult.[6]
