historiography is the study of the history and methodology of the discipline of history. the historiography of science is thus the study of the history and methodology of the sub-discipline of history, known as the history of science, including its disciplinary aspects and practices (methods, theories, schools) and to the study of its own historical development ("history of history of science", i.e., the history of the discipline called history of science). since historiographical debates regarding the proper method for the study of the history of science are sometimes difficult to demarcate from historical controversies regarding the very course of science, it is often (and rightly) the case that the early controversies of the latter kind are considered the inception of the sub-discipline. for example, such discussions permeate the historical writings of the great historian and philosopher of science william whewell. he is thus often (and rightly) viewed as the grandfather of this discipline; other such distinguished grandfathers are pierre duhem and alexandre koyrÃ©. as to the explicit presentation of the historiography of science it is usually dated in the early sixties of the 20th century. thus for example, in 1965 we find gerd buchdahl reporting "a revolution in historiography of science" referring to the innovative studies of thomas kuhn and joseph agassi. he suggested that these two writers had inaugurated the sub discipline by distinguishing clearly between the history and the historiography of science, as they argued that historiographical views greatly influence the writing of the history of science. == the origins of the discipline ==  though scholars and scientists had been chronicling the results of scientific endeavors for centuries (such as william whewell's history of the inductive sciences from 1837, and the popular and historical accounts which accompanied the scientific revolution of the 17th century), the development of the distinct academic discipline of the history of science and technology did not occur until the early 20th century, and was intimately bound to the changing role of science during the same time period. the history of science was once exclusively the domain of retired researchers &mdash; former scientists whose days in the laboratory had expired but still with a hearty interest in the field &mdash; and the rare specialist. however in the decades since the end of world war ii the field has evolved into a full academic discipline, with graduate schools, research institutes, public and private patronage, peer-reviewed journals, and professional societies. outsiders are often amazed that
