This book is a photographic roster of several hundred of Wisconsin's most prominent male citizens at the time of publication in 1902. The oval head-portraits are displayed four to a page, accompanied by the subject's name, occupation (or distinguishing achievement), and place of business; they are loosely grouped by occupational type. Though many of those represented are lawyers, there are also a number of manufacturers, as well as physicians, bankers, judges, politicians, civil servants, insurance and real-estate executives, journalists, architects, military officers, clergy, educators, and individuals involved in such occupations as lumbering, farming, retail, other areas of business, and the arts. An introduction celebrates the state's prosperity, and there is an index of names.
