The Roslin Institute of the University of Edinburgh is a major international centre for research on the molecular and quantitative genetics of farm animals. This photograph is part of a series of four images which show the key members of the team that created Dolly the sheep, the first mammal cloned from an adult cell. The series tracks the main stages of the cloning process. Here, Bill Richie, the Embryologist, is shown in the micro-manipulation lab. In the 1990s the photographer Wendy McMurdo was already exploring the idea of the perfect copy in relation to cloning, a parallel concern of the scientific world. As part of this commission McMurdo wanted to explore each person’s individual contribution to an event of great significance.
