Frances Erskine Inglis

Frances "Fanny" Erskine Inglis, later the Marquesa of Calderón de la Barca and best known as Fanny Calderón de la Barca, (Edinburgh, Scotland, 1804 – Madrid, Spain, 1882), was a 19th-century travel writer best known for her 1843 memoir, Life in Mexico, which is regarded by historians as one of the most influential Latin American travel narratives of the 19th century.

The Inglis family immigrated to the United States in 1835. Fanny married a Spanish diplomat, Ángel Calderón de la Barca y Belgrano, in 1838. In 1839 she accompanied him on his posting to Mexico. In 1843, the couple returned to the U.S. and Calderón de la Barca published Life in Mexico. In 1852, the couple moved to Madrid, Spain where Ángel had been appointed as a Minister of State by the royal government of Spain. In 1856, Fanny Calderón de la Barca's book The Attaché in Madrid, was published in the United States. The book never achieved the popularity of Life in Mexico.

After her husband died in 1861, Calderón de la Barca served as the governess of Infanta Isabel, the daughter of Isabella II of Spain. In 1877, she was awarded the title, Marquesa de Calderón de la Barca. She died in Madrid on 6 February 1882 at the age of 77.
