This prize recognizes outstanding scholarly achievements in the history of physics. Outstanding scholarly achievements are reflected primarily in the publication of one or more scholarly books or a series of scholarly articles on any topic or chronological period in the history of physics. These can include significant editions of works of physicists that display outstanding editorial scholarship; other edited books or collections of previously published articles will be considered but given less weight. Further outstanding professional achievements such as teaching, lecturing, editing of journals, organization of conferences, and productions on the Web or in other electronic media may be considered if they have contributed significantly to fostering excellence in the history of physics. The Award usually is given to a single person but to no more than three individuals. It is granted without restriction. It is open to scholars of all nationalities; membership in a scholarly or professional society is not required.
