Mr. M. Joseph McCosker, Director of the Atwater Kent Museum, and his assistant, Mr.
Charles T. Bryan, spent many hours segregating pertinent material for us. Mr. Lessing
J. Rosenwald has shared our enthusiasm and given generously of his interest and advice.
We owe to Mr. Penrose Hoopes, Chairman of the Library Committee, and Mr. John P.
McGowan, Librarian, appreciation for their assistance in our search for drawings in the
collections of the Franklin Institute. The Pennsylvania Academy of the Fine Arts, the
Academy of Music, the Kean Archives, and the Grand Lodge, Free and Accepted Masons
of Pennsylvania have all lent material from their collections.

All of us who have had anything to do with the publication of Penn's Great Town
are especially appreciative of the encouragement and assistance that we have received from
the staff of the University of Pennsylvania Press and from its director, Mr. Thomas Yoseloff.
We have been especially heartened by the willingness of the Press to undertake a project
of this magnitude while under the severe restriction of time and without any guarantee of
financial assistance from either individuals or foundations. In all our plans for the book
Mr. Yoseloff and his associates have moved with us when they were not already ahead of us.

This Foreword also presents a welcome opportunity to acknowledge the part played
by the other members of the Committee, especially in preparing for the exhibition. These
are: Mr. Paul C. Harbeson, Mrs. Marian Mitchell, Mr. Beryl Price, Dr. David M. Robb,
and Dr. George B. Tatum. Our only regret is that, since this book must go to press almost
a year before the opening of the exhibition, it is not possible to express in print our ap-
preciation for the contribution of others upon whom we may still call for assistance. These,
we hope, will find their satisfaction in the success of the completed show.

I am aware that personalities have little place in a foreword; I beg special privilege. I
have worked closely with Dr. George Tatum through the winter and spring of 1959-60,
offering what small assistance I could in the preparation of the book and the earmarking of
items for the exhibition. The book is a monument to his scholarly dedication to his subject.
The association has been a fine and rewarding experience to me and has rendered a warm
friendship an even deeper thing.
