Marvin Harris (August 18, 1927 – October 25, 2001) was an American anthropologist. He was born in Brooklyn, New York City. A prolific writer, he was highly influential in the development of cultural materialism. In his work, he combined Karl Marx's emphasis on the forces of production with Thomas Malthus's insights on the impact of demographic factors on other parts of the sociocultural system. **Source**: <a href="https://en.wikipedia.org/wiki/Marvin_Harris">Marvin Harris</a> on Wikipedia (Wikipedia contributors, <a href="https://en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_Attribution-ShareAlike_3.0_Unported_License">CC BY-SA 3.0</a>).
