Our brief survey of the Josephson junctions will be started with tunnel junctions proposed1 in 1960 by Ivar Giaever who later shared the Nobel Prize with Brian Josephson. These were the tunnel junctions for which the original Josephson prediction was madeP.1 and in which the effect was experimentally observed for the first time.P.2 Despite a considerable competition from the junctions of other types, the tunnel structures are still the best studied and the most important for applications.
