1950-1975: PROGRESS CONTINUES.

Almost from the beginning, each of the annual symposia on the Biology of Skin has been devoted to a single subject. The format has been fairly rigid: the first paper introduces the chosen subject, which is then discussed in detail in subsequent manuscripts. However, the purpose of this twenty-fifth symposium is not to pour over one cell, one organ, or one mechanism. Commemorating as it does a quarter of a century of biomedical research that was stimulated to adulthood by one man, this symposium marks a 25th anniversary and stands as a monumental tribute to biologist William Montagna.
