Final answer:
Monica McGoldrick is the person who continued Bowen's work, incorporating gender and ethnicity into the study of family systems.
Step-by-step explanation:
The person who continued Bowen's work and added gender and ethnicity to the study of family systems was Monica McGoldrick. She is known for her significant contributions to the field of family therapy, including her perspective on how cultural context, ethnicity, and gender influence family dynamics. McGoldrick's work expanded upon the foundations laid by earlier anthropological researchers, such as Ruth Benedict, Margaret Mead, and Edward Sapir, who explored aspects of psychological anthropology, and W. H. R. Rivers, who worked in medical anthropology and denounced the 'noble savage' myth.
