This project began as a collaborative study between CCAHA Photograph Conservator Rachel Wetzel and Library of Congress Senior Photograph Conservator Adrienne Lundgren. Together with a team of specialists, they are investigating the effects of historic cleaners on daguerreotypes. In 2016, they received a National Endowment for the Humanities (NEH) Research and Development grant to fund the creation of an online database of the work of Philadelphia photographer Robert Cornelius, who made many contributions to the daguerreotype process in the mid-19th century. 

The team: 

  • Edward Vicenzi, Research Scientist at the Smithsonian’s Museum Conservation Institute
  • Mike Robinson, modern-day daguerreotypist
  • William Stapp, former Curator of Photographs at the National Portrait Gallery
  • Andrew Robb, Head of Special Format Conservation in the Conservation Division of the Library of Congress
  • Beverly Brannan, Curator of 20th-century Documentary Photography at the Library of Congress
  • Sarah Weatherwax, Curator of Prints & Photographs at the Library Company of Philadelphia
  • Paul Messier, Head of Yale University's Lens Media Lab
