Dartmouth College is celebrating the 20th anniversary of a project aimed at getting more women to major in science, math and engineering.

Since the Woman in Science Project began, the number of women majoring in those subjects has grown from 45 to 102. The project has been tweaked over the years, but the main elements include research internships that pair female first-year students with faculty researchers, peer mentoring, teacher seminars and an electronic mentoring network.

The project was co-founded by Karen Wetterhahn, a chemistry professor who died in 1997 as a result of a lab accident involving a toxic mercury compound.
