The advent of methods for forming and studying lipid bilayer membranes (Mueller et al. 1962; Hanai et al. 1964) opened the way for some fifteen years of intensive and productive study of the properties of lipid soluble ions and ion carriers. I expect that none will dissent from the view that Peter Läuger and his associates, including R. Benz and G. Stark, did more than any other research group to advance the study of the mechanism of the charge transfer. Between 1970 and 1981 they published more than 25 substantial contributions. Thus it is appropriate that this memorial issue should contain a short review of this subject. As I have the highest regard for their work I was very pleased to be asked to write such a chapter. There is little point in providing another general survey because Läuger's group published reviews at the end of this period (Benz et al. 1980; Läuger et al. 1981) and I also reviewed the field at length (Hladky, 1979a). Instead I would like to consider the three cornerstone papers of 1971, some of the difficulties that arose from those papers, how they were overcome, and three aspects of the description that are still incomplete.
