Publisher Summary This chapter discusses a problem of concern to applied microbiologists which is not strictly scientific in nature, however, if properly understood, could constitute a real advance in applied microbiology. The problem is the training required for a modem, successful, and applied microbiologist. The chapter also discusses the matter of the proper training of applied microbiologists, and suggests that it will be exceedingly difficult to obtain a general agreement on the subject. It seems reasonable that the kind of training necessary should be directed more to the average person than to the genius. For the genius, nothing is difficult; the trick is to be able to do things with a minimum of natural talent.
