Abstract
Since the beginning of this century the platinum resistance thermometer has been relied upon as a most convenient means of temperature measurement and control in industrial applications, while its accuracy in precision thermometry has contributed largely to the definition of the International Temperature Scale. Its origin stems, however, from the early years of the costly and hazardous attempts to lay underwater telegraph cables, before even a standard unit of resistance had been generally adopted.
