"Many people think of history as something divided chronologically and geographically. A historian might say that she specializes in Japanese history or the history of the Middle Ages. History of science, however, is a thematic division. A historian of science might study the history of vaccination, the history of celestial mechanics, or the history of scientific institutions. History of science students at Berkeley can be found in several departments, including history, art history, English, and philosophy. The Department of History offers a graduate field (MA/PhD) in the history of science. Graduate students in the history of science at Berkeley enjoy a kind of dual citizenship: not only are they enrolled in a top-ranked doctoral program, but they also have full access to the resources available in the Office for History of Science and Technology. At Berkeley, students learn to see the practice of science as related to its cultural, intellectual, and historical context. The paired resources of OHST and the departmental doctoral program provide PhD students with a strong grounding in both the special field of the history of science and the larger discipline into which it fits."
