versity, state, and federal authorities, who often had recourse to his wide
knowledge and abundant wisdom. He was devoted to his former students, and
they took much of his time. When L. J. Pae tow's untimely death in 1928 left
unfinshed the revision of his Guide to the Study of Medieval History, Munro
undertook its com pletion, assisted by Professor Gray C. Boyce, who now prepares
the third edition of Paetow, and whose wide bibliographical know ledge has
been placed at the disposal of this History o/the Crusades, for he will be
the editor of Volume V. After Munro's death in 1933, on the eve of his retirement
from Princeton, it soon became clear that all the writing he had been able
to do for some time before his death was The Kingdom ot the Crusaders, which
Professor August C. Krey prepared for the press in 1935. But Munro had often
discussed his plans for a detailed history of the crusades with his friends
and former students, especially with Krey and with Professor Frederic Duncalf.
The latter's summer home at Waquoit, Massachusetts, was the scene of several
such sessions, which still remain most treasured memories to Duncalf and
to Krey. It is to these two that we owe the inception of this History, although
the project gained a vast momentum when the twain was made a trio by the
addition of the late Professor John L. LaMonte. 
 The friendship of Krey and LaMonte began about 1930 when LaMonte taught
Krey's courses while Krey was on a year's leave of absence from the University
of Minnesota. Duncaif and LaMonte met for the first time in December 1935
at the annual meeting of the American Historical Association, held that year
in Chattanooga, Tennessee. It was Duncaif who first proposed that a cooperative
history of the crusades be undertaken by Munro's former students together
with others who might be interested in joining them in such a venture. Krey
was, of course, a firm sup porter of the idea. Nothing was done, however,
until three years later. At the meeting of the Historical Association held
in Chicago in 1938, with Duncaif in the chair, LaMonte read a paper on "The
Crusades Reappraised," 3 which was later published as "Some Problems in Crusading
Historiography." 4 After discussion, a com mittee of medievalists was formed
to make plans for a cooperative history of the crusades; LaMonte proved to
be a very popular preacher, and recruits were gathered for this crusade of
scholar ship from the chief universities in the United States. Duncaif was
