This issue contains the obituaries of two of the greats in our field, and itis tempting to regard it as the end of an era. Hans Eysenck and Joseph Wolpewere truly giants in the field, truly founding fathers of scientificcognitive-behavioural therapy. Their passing is a landmark, but clearlynot the end of an era. The era that they ushered in was one inwhich the basis of psychopathology and treatment lay in well defined theoryand rigorous, well conducted research. That philosophy has grown, developed,and has given us a scientific basis for cognitive-behavioural therapy.

I believe that it is no coincidence that both men intended, at an earlyage, to follow a career in the physical sciences. They had many othercharacteristics in common, including a firmness of purpose that served boththem and the field well. Isaac Newton, writing to Robert Hooke, said of hisachievements that “If I have seen further it is by standing onthe shoulders of Giants”. Eysenck and Wolpe were such giants, and we should be grateful for their shoulders, and for the visionthat their achievements allow us.
