Mannequin or manikin has undergone several changes since they were introduced in
the 15th century. The earlier manikins were used by fashion producers to evaluate
size and fit, and in window display. The technological developments have led to the
design of manikin that can provide objective results for a controlled environment such
as automotive interior and perform objective tests to evaluate various parameters of
protective clothing used in areas such as firefighting, defense, hot metal splash, and
cold weather protection. This chapter deals with the history of manikin development
including their chronological developments. This chapter also covers different types
of manikins, recent developments, and their application areas in various fields. A
brief description on the contents of each chapter has also been included. This chapter
will help the readers to gain preliminary knowledge of manikins before reading other
chapters, which are focusing specific areas of application.
