Doc Brown

Dr. Emmett Brown was the iconic deuteragonist of the trilogy. He was the inventor of the DeLorean time machine. He is the world's third time traveler (after Einstein and Marty McFly), the second to travel forwards in time (after Einstein), the first human to travel forwards in time, and the second human to through time (after Marty).

A scientist by trade, Doc was a "student of all sciences" who spent much of his time inventing. He was the son of Judge Erhardt Brown (whose birth name was Erhardt Von Braun) and. He usually had a pet dog – in 1955, his dog was named Copernicus after Nicolaus Copernicus, the third in a line of pets named after famous scientists, and by 1985 his dog was named Einstein after Albert Einstein.

Doc's role models were scientists, as evidenced by the names of his dogs and the portraits of Isaac Newton, Benjamin Franklin, Thomas Edison, and Albert Einstein found in his laboratory (which were on his fireplace mantle in 1955).
