Alexander Graham Bell

Alexander Graham Bell was a human scientist born on Earth. He was best known for his invention of the telephone. The very first phone call, made by Bell to his assistant Thomas Watson ,"Watson, come here, I need you.", bled through onto Sonny Hoskins' portable phone and Rose Tyler's anachronistic mobile phone in 1987. This was just as a time breach occured as a result of Rose saving her father, an act strictly forbidden, as his death was a fixed point in time. (DW: Father's Day)
