This post is the first in a four-part series between Kveller, the Jewish Women’s Archive, and Jewniverse commemorating women in STEM (science, technology, engineering, and mathematics) for Jewish American Heritage Month. Every Monday in May you can look forward to a new post about a Jewish woman who helped to lay the groundwork for women in science today.
