favor greater care for public safety" was aimed directly at
alternating current..
It was Hastings who mobilized the facilities Edison's
laboratory for Brown and his colleague Petersen, nerve
specialist from Vanderbilt Hospital. More electrocution experiments were
organized Hastings the fall and winter 1888.
Kennelly reported that the experiments were done a
hurry, with makeshift equipment, and the whole process normally
taking less than hour. Brown and Petersen
electrocuted animals the West Orange laboratory and a

demonstrate the dangers alternating current. the spring 1888 Brown began a
publicity campaign draw attention the "large number of
