Michel Janssen is a professor in the Program in the History of Science, Technology, and Medicine at the University of Minnesota. Before coming to Minnesota, he was a member of the editorial team of the Einstein Papers Project, then at Boston University. He has published extensively on the relativity and quantum revolutions of the early twentieth century. Christoph Lehner is a research scholar at the Max Planck Institute for the History of Science and the coordinator of its project on the History and Foundations of Quantum Mechanics. He has been an editor at the Einstein Papers Project at Boston University and at the California Institute of Technology, and has been a scientific advisor for the 2005 exhibit 'Einstein, Chief Engineer of the Universe' in Berlin. The focus of his research is the history and philosophy of quantum theory.
