Starting fresh

After the success of Menlo Park, Edison built a new laboratory complex in 1887, bigger and better equipped in every way, in West Orange, New Jersey. There, he worked on all sorts of projects, ranging from movies to ore mining to batteries to cement.There were happy times and sad ones in his personal life. His first wife, Mary, died in 1884 and he remarried two years later to a young socialite named Mina Miller. From the two marriages, he had 6 children, one of whom became governor of New Jersey, another who followed his own career of invention.
