Old ETOX Group Photo

Yesterday, Eduardo de la Pena, a scientist from Spain who spent a year working in my lab dropped by to visit.  It reminded me of a photo from about 1995 that was taken of many of the Environmental Toxicology group during an earthquake drill when Elizabeth, my wife, just happened to be walking by on her way to her photography lab with her camera.  Below is the picture.  Eduardo is kneeling in the front on the right.
