  Experiments on one-dimensional small capacitance Josephson Junction arrays
are described. The arrays have a junction capacitance that is much larger than
the stray capacitance of the electrodes, which we argue is important for
observation of Coulomb blockade. The Josephson energy can be tuned in situ and
an evolution from Josephson-like to Coulomb blockade behavior is observed. This
evolution can be described as a superconducting to insulating, quantum phase
transition. In the Coulomb blockade state, hysteretic current-voltage
characteristics are described by a dynamic model which is dual to the
resistively shunted junction model of classical Josephson junctions.
