The Director for the Medical Sciences at the Rockefeller Foundation tells in this book what medical research is, what the universities and foundations have done and should do about it, and of the kind of man who works at the frontiers of the unknown in order to push back the curtains of darkness at least a little in the endless search for truth.  Dr. Gregg candidly discusses some of the shortcomings of the foundations and their methods, the obstacles to their and the universities' doing their job properly, the booby traps and temptations that like in their way.  But here at firsthand is an account of the men of good will, with none of the sanctimoniousness that has often characterized philanthropic endeavors, of men who critically, earnestly, doggedly, and intelligently have labored in the heat of the day and from whose minds will come the advances of the future.    ?This short book is addressed to the entire medical profession, to the medical student, to the student who contemplates entering medicine, and to many in the allied and basic sciences.  It should be read by any who evince or profess an interest in medical research.??Journal of the American Medical Association     ]]>
