Ruth Benedict
Opposition to racism revived in the 1920s and 1930s. At that time, anthropologists such as Franz Boas, Ruth Benedict, Margaret Mead, and Ashley Montagu argued for the equality of humans across races and cultures. Eleanor Roosevelt was a very visible advocate for minority rights during this period. Anti-capitalist organizations like the Industrial Workers of the World, which gained popularity during 1905–1926, were explicitly egalitarian.
