Elizabeth Terwilliger

Elizabeth Terwilliger (September 13, 1909 – November 27, 2006) was an American environmental activist and educator based in Marin County, California.

She then studied nursing at Stanford University, where she met her husband, Calvin Terwilliger, who was a surgeon.

[3] In the 1950s, there was a plan to fill Richardson Bay to create a town called Reeds Port.

Terwilliger, working with the Marin Audubon Society and Caroline Sealy Livermore, contacted L. Martin Griffin to enlist him in the ultimately successful effort to stop the development.

This led to Terwilliger, known to children as "Mrs. T," leading nature walks for local schools and organizations, which she would continue into her 80s.
