Women of Science is a collection of essays dealing with contributions women have made to various scientific disciplines, written by women scientists in those disciplines. The areas covered are: astronomy, archaeology, biology, chemistry, crystallography, engineering, geology, mathematics, medicine, and physics. The women who have written these essays are, for the most part, not professional historians, but rather scientific professionals who felt the necessity of researching the contributions women have made to the devlopment of their fields. The essays are unique, not only because they recover lost women who made significant contributions to their disciplines, but also because they are written with a depth of understanding that only a scientist working in a specific area can have. The essays will be of interest not only to students (especially women students) of science who may be unaware of the many contributions women have made, but also to readers of the history of science whoses texts more often than not fail to include the work of most women scientists.
