Foreword by Margit von Mises

When my husband died in 1973 I had to go through his papers. Some of them were still in manuscript form and had never before been published. I selected several of these, plus a number of other articles that had appeared in periodicals but were no longer in print. This book is the result.

At my request Richard Ebeling wrote an introduction which he has done in great detail. The depth of Ebeling’s understanding of my husband’s work is certainly apparent in his writing.

I am pleased to have the Ludwig von Mises Institute present this volume to the public.
