Book excerpt: This book was written to document the part played by the Massachusetts Institute of Technology, its staff, its former students and its undergraduates. Tales of skill, self-sacrifice and courage displayed by "Tech" men are preserved as an inspiration to their comrades and descendants. Attention is directed to the fact that such an institution as "Technology" is not only a valuable auxillary in developing commerce and industry in time of peace but that in time of national emergency it becomes an indispensable part of the Nation's military organization.
