?Martin Panusch is working with Peter Heering at the University of Flensburg on the history of the apparatus that Robert Millikan used in his Nobel Prize winning research on the charge of the electron.  He is recreating the instrument as part of an investigation into its performance and an understanding of the skills of the experimenter.  

His work has already taken him to CalTech and the University of Chicago in search of clues. His visit to Aarhus is occasioned by inspection of a period chronometer at the Steno Museum.
