After serving as Assistant Professor in Entomology at Stanford University, Dr. McCracken was Professor of Zoology at the same university until her retirement in 1931. She was a Research Associate at the California Academy of Sciences from 1931 through 1945 and worked on the birds and insects in the collections of the Academy. Dr. McCracken spent some of her time volunteering in organizations such as the Children's Museum in Palo Alto, the Stanford Convalescent Home and other organizations that cared for the unfortunate.
