“They were made at a time when the concept of nanotechnology, even the word at that time didn’t exist.”
Physicist Volker Rose is working with Ed Vicenzi at the Argonne National Laboratory. They are using the laboratory’s Advanced Photon Source to learn more about the daguerreotype.
“The technology that’s available at the Advanced Photon Source will allow me to study the very earliest stages of degradation of daguerreotype plates. They corrode over time, not quickly necessarily, but we need to learn the chemical mechanisms in order to understand how we can preserve these objects for the future.”
Ed Vicenzi hopes his efforts at Argonne will provide the answers historians and collectors need to save these images of the past. He says this will make it possible for future generations to study, understand and appreciate what life was like in the 19th century.
Many thanks to my friend, colleague, and …by the way…excellent photographer Steve Ember for that information. I’m Jim Tedder in Washington. More Learning English programs are just ahead. And there is world news at the beginning of the hour on VOA.
