phycologist and limnologist specializing in diatoms and hydrobiology, Ruth M. Patrick (1907-2013). She developed innovative ways to assess the quality of freshwater ecosystems, in particular using diatoms, authored&gt;200 scientific papers, and established numerous research facilities, in particular the Phycology Section at the Academy of Natural Sciences of Philadelphia (ANSP, part of Drexel University since 2011). We consider this last achievement notable in the international museological context, as a bright example of a part of the research division (ANSP’s Patrick
