The first century of modern surgery was dominated by strong personalities e
ach of which have formed a leading surgical school and a great hospital. Th
is was beneficial for the young science as long as all areas of the develop
ing surgery could be mastered by one single man. A consequence of great and
ever faster progress in all sciences and particulary in medicine is a more
and more narrower specialisation. This trend has made it impossible for an
individual to be on the forefront of developments in the major surgical di
sciplines. Thus, to fulfill important tasks and especially for further prog
ress it is mandatory to use the diverse skills of different individuals as
a team.
