In 1867, Bell and his family moved to London so that he and his remaining brother could study at better schools. Prior to moving to London, Bell had been experimenting with using electrical current to send sounds from one place to another. He set up a telegraph wire from his Somerset College room to the room of a friend in a different building. Later that year, Bell's second brother passed away. The family mourned, but Bell and his father were in the middle of a tour of English colleges doing demonstrations on speech innovations, including sign language and advanced lip-reading techniques. Bell and his father had created a laboratory where they were conducting their experiments, and they had several techniques that were getting the attention of speech experts from all over the country.
