Please help us to identify the individuals in these photographs.  A few at the end are known (Sauer, Gregg, Northrop, DeChartin, Coon), but most are not.  If you recognize any of these individuals, please let us know.  Refer to the photo number and give an indication of your confidence in the identification.  Please feel free to bring this to the attention of others who may know these individuals.  

While the photos may well include individuals who were not authors at the Symposium, and most authors are not included in the pohtos, it's likely that some of these photos are of the authors.  The following list is included, therefore, in hopes that this helps in the identification process.  *Astrisks indicate that a photo is included at end of photos.   If you have any photographs of these individuals, please send them to us.
