Dear colleagues,

I am sad to report that a true pioneering scientist, Sister Mary Ellen 
Murphy, passed away yesterday. She was part of the founding generation 
of researchers in our field, and helped bring organic geochemistry into 
the modern era, notably through her work on lunar samples and in the 
Viking missions.

A news release on Sr. Murphy can be found on the website of Univ. of 
Saint Joseph, where she was a Professor of Chemistry, and Trustee Emerita.
