Nikola Tesla. On His Work With Alternating Currents and Their Application to Wireless Telegraphy

This work is dedicated to the late Philip D. Jordan, Professor emeritus of American history, University of Minnesota, who pressed his students to the review of legal records in historical research. "Indeed, few historians, librarians, and archivists recognize the significance of legal materials... . Yet the law, in one way or another, is the basis of most institutions—political, social, cultural, economic. ... It is unfortunately a truism that graduate students are seldom introduced to legal materials."
