Andrew Dickson White (November 7, 1832 - November 4, 1918) was an American historian, diplomat, and educator best known as a co-founder and first president of Cornell University. He also served as U.S. Minister to Germany and Russia, and as ambassador to Germany under President McKinley. His major intellectual contribution, and the most contested, is his 1896 work A History of the Warfare of Science with Theology in Christendom, which advanced the thesis that the history of Western civilization has been characterized by fundamental conflict between scientific inquiry and Christian theological authority.

White's career spanned academic institution-building, diplomacy, and historical scholarship. As Cornell's first president (1866-1885), he helped establish a non-sectarian research university at a time when American higher education was dominated by denominational colleges. His diplomatic postings gave him direct experience with European political and intellectual culture. As a historian, he wrote on topics ranging from German unification to the French Revolution, though his reputation today rests primarily on his conflict thesis regarding science and religion.

White's Warfare book, along with John William Draper's earlier History of the Conflict between Religion and Science (1874), gave rise to what historians of science call the “conflict thesis” - the view that science and religion are inherently and historically at odds. White drew on a wide range of historical episodes, including the Galileo affair, debates over Darwinian evolution, and disputes about biblical cosmology, to argue that theological dogmatism had systematically impeded scientific progress.

Subsequent historians of science have extensively revisited White's evidence and methodology. The scholarly consensus among historians of science today holds that the conflict thesis is an oversimplification, and that the actual relationship between science and religion across history has been complex, varied, and often cooperative rather than adversarial. White has been criticized for selective use of sources, anachronistic framing, and constructing a narrative that served his institutional interests in defending non-sectarian higher education. That said, some historians continue to find partial merit in his account for specific periods or episodes. For the state of scholarly debate, see Conflict Thesis - History of Science Consensus.

Together with Ezra Cornell, White founded Cornell University in Ithaca, New York, with an explicit commitment to admitting students regardless of religious affiliation and to offering practical and scientific education alongside classical subjects. This was a significant departure from the prevailing model of American higher education. White faced substantial opposition from denominational colleges and clergy who viewed the non-sectarian model as hostile to Christianity. His later historical writings on science and theology are widely understood, at least in part, as a continuation of that institutional argument by scholarly means.

White served as U.S. Minister to Germany (1879-1881) and to Russia (1892-1894), and as Ambassador to Germany (1897-1902). He was a delegate to the First Hague Peace Conference in 1899. His diplomatic writings and memoirs offer primary source material on late 19th-century European affairs and American foreign policy of the period.

Historians of science broadly agree that White's conflict thesis does not accurately represent the historical relationship between science and religion as a whole. This consensus is well-established within the academic history of science. See Conflict Thesis - History of Science Consensus for scope and caveats.

• Conflict Thesis Vindicated-viewpoint - The view that White's core argument remains substantially correct, even if details require revision, and that institutional religion has historically been a net obstacle to scientific progress.
• Conflict Thesis Rejected-viewpoint - The view that White constructed a polemical narrative rather than an accurate history, and that the science-religion relationship defies the warfare model.
• Partial or Contextual Conflict-viewpoint - The view that neither wholesale acceptance nor rejection is warranted, and that the conflict thesis holds for some episodes, institutions, or periods but not as a universal law.
• Institutional Advocate Reading-viewpoint - The view that Warfare is best understood as advocacy literature for non-sectarian higher education rather than as dispassionate history, regardless of whether its core claims are correct.
