In 1896, Florence Bascom became the first woman to be employed by the U.S. Geological Survey.

In the 1920s, J Harlen Bretz revealed that the Channeled Scablands in eastern Washington were caused

In 1935, Charles Francis Richter and Beno Gutenberg developed the Richter scale.

In the 1960s, Harry Hammond Hess, Robert S. Dietz, and J. Tuzo Wilson proposed
the concept of seafloor spreading, providing the framework
for the theory of plate tectonics.

What do they, and many other famous geologists,
all have in common?
