Lewis H. Morgan

Lewis Henry Morgan was a pioneering American anthropologist and social theorist who worked as a railroad lawyer. He is best known for his work on kinship and social structure, his theories of social evolution, and his ethnography of the Iroquois. Interested in what holds societies together, he proposed the concept that the earliest human domestic institution was the matrilineal clan, not the patriarchal family.

Lewis and his wife were active in the First Presbyterian Church of Rochester, mainly of interest to Mary. Lewis refused to make the public profession of Christ that was necessary for full membership. They both contributed to and sponsored charitable works. In 1856, Mary Elisabeth was born and in 1860 Helen King.
