Her life story was also chronicled in the book Gaby Brimmer: An Autobiography in Three Voices, written by Elena Poniatowska.
She had extended family already working in Mexico City, including her cousin Petra, and when she first arrived she held odd jobs.
After a year of regrouping, Morales, now in her late 20s, went back to Mexico City, and she was referred to the Brimmer family, who was looking for hired help.
She was originally hired in 1949 as a maid by her parents, Sari and Michel Brimmer, who were Jewish-Austrian and living in Mexico after moving there as refugees from Europe during World War II.
Morales was credited for helping Brimmer develop better communication skills so she could live a healthier life and begin to write.
Morales traveled with Gaby when she was living in the United States undergoing testing and procedures in an attempt to cure her cerebral palsy.
The New York Times wrote: "As the film presents this, the nurse, Florencia Morales, was largely responsible for teaching Gaby to communicate...Miss Aleandro is a marvel, conveying both the shyness and the meddlesomeness of someone living in so symbiotic a situation".
