Andrew Dickson White (November 7, 1832 – November 4, 1918) was a U.S. diplomat, author, and educator, best known as the co-founder of Cornell University. In 1869 White gave a lecture on "The Battle-Fields of Science", arguing that history showed the negative outcomes resulting from any attempt on the part of religion to interfere with the progress of science. Over the next 30 years he refined his analysis, expanding his case studies to include nearly every field of science over the entire history of Christianity, but also narrowing his target from "religion" through "ecclesiasticism" to "dogmatic theology."
