Isabel Gutiérrez del Arroyo

Isabel Gutiérrez del Arroyo Mimoso (November 16, 1907 – January 2004) was a Puerto Rican historian. Originally a schoolteacher, she obtained degrees from the University of Puerto Rico and El Colegio de México. A 1955 Guggenheim Fellow, she specialized in Puerto Rican history and was a professor at UPR. Biography Isabel Gutiérrez del Arroyo Mimoso was born on November 16, 1907, in Bayamón, Puerto Rico, one of four daughters of Isabel ( Mimoso) and Rafael Gutiérrez del Arroyo.

After briefly returning to Mexico as a United States history professor at Mexico City College and a Colmex researcher (both 1954–1955), she served as historian of the Instituto de Cultura Puertorriqueña from 1956 until 1961. She remained with UPR until 1977 and eventually become a professor emeritus there. In 1955, she was awarded a Guggenheim Fellowship to study the colonial Mexican intendancy system. She believed researching and preserving Puerto Rican history to be the best way to serve her people. According to Lizette Cabrera Salcedo, "her greatest legacy was becoming a historian of Puerto Rican identity". Her library was donated to UPR's Center for Historical Research in 1997.
