https://history.ncfr.org/
NCFR is the only professional organization focused solely on family research, policy, and practice. It was founded in 1938 by Paul Sayre, a law professor at the University of Iowa, Ernest Burgess, professor of sociology at the University of Chicago, and Rabbi Sidney E. Goldstein, Chair of the Central Conference of American Rabbis, New York City.
From its inception, NCFR was organized by state and regional affiliates and by subject area sections related to the principal areas of Family Science. The national office is located in Saint Paul, Minnesota. NCFR is governed by a board of directors composed of professionals from across the country.
