Curriculum vitae:

Robert de Levie was born and raised in Amsterdam, the Netherlands, and earned his Ph.D. in physical chemistry at the University of Amsterdam. He was a postdoctoral fellow with Paul Delahay at LSU in Baton Rouge LA for two years, and then for 34 years taught analytical chemistry and electrochemistry at Georgetown University in Washington DC. For ten of those years he was the US editor of the Journal of Electroanalytical Chemistry. Now an emeritus professor, he lives on Orr's Island, and is associated with Bowdoin College in nearby Brunswick ME.
