Mary T. S. Schäffer’s reputation as an artist, author, photographer and explorer is best illustrated by her own delightful accounts of rugged camp and trail life in the Rocky Mountains of Canada in the early 1900s. In 1980, the Whyte Museum published a compilation of Mary Schäffer’s works as A Hunter of Peace, edited by E. J. (Ted) Hart, which was the catalyst for a resurgence of interest in Schäffer’s work. Now, by revisiting Schäffer’s original manuscripts contained in the Archives and Library of the Whyte Museum, the spectacular second edition of A Hunter of Peace even more fully reflects Schäffer’s work and intent. Context and guidance for the second edition of A Hunter of Peace were found in the original Old Indian Trails and Schäffer’s photograph albums. This research resulted in the addition of Schäffer’s original foreword to the new edition as well as more images and illustrations.
