It seems appropriate that the Journal following the Centenary Issue should contain tributes to three Jungians of international repute, whose seventieth birthdays occurred within or around the same year.

Obviously, the Journal cannot honour every analytical psychologist who reaches the age of seventy and is still in harness. Some of these would, no doubt, be equally good analysts, equally liked and appreciated by their colleagues and former patients. The three men we have singled out for special mention have achieved eminence because of their publications and the notceable energy with which they devoted themselves over many years to our special field of study.

The Editor and assistant editors express the hope that all three colleagues will continue to emulate their illustrious sire's creative longevity.
