The Archives, IHP, has preserved twenty volumes of name registrations and minutes of IHP lectures from 1959 to 1969, which record the contents and Q&As of these academic talks. Starting in 1947, we have been regularly conducting “IHP Lectures” every two weeks, a tradition of which continues even today. In these lectures, IHP research fellows are encouraged to present their academic ideas and engage in debates with other scholars. The lecture minutes from the above period are summaries usually written by other IHP research fellows, sometimes including manuscripts or outlines provided by the speakers, and many of these lectures would later be submitted and published as formal articles. Thus, examining these minutes allow us a comprehensive understanding of the development processes of academic ideas, as well as how they were challenged and eventually published.
