Actually, how long have people been active in science? The answer is the same for both women and men -- as long as we have been human. One of the defining marks of humanity is our ability to affect and predict our environment. Science - the creation of structure for our world - technology - the use of structure in our world - and mathematics - the common language of structure - all have been part of our human progress, through every step of our path to the present. Women and men together have researched and solved each emerging need.
This site compiles over 130 biographies of women scientists throughout the ages organized alphabetically, chronologically, and by discipline. A handful of images are also available, as is an extensive bibliography. Unfortunately most of the site has not been updated since 1999 and many of the off-site links are no longer valid.
