Dr. Emmett Lathrop Brown, commonly referred to as "Doc Brown", is a fictional scientist in the Back to the Future franchise. He was created by Robert Zemeckis and Bob Gale. First appearing in the 1985 film Back to the Future, he is an eccentric mad scientist and friend to the protagonist Marty McFly. In the franchise, he invents a time machine using a DMC DeLorean. He is portrayed by Christopher Lloyd in all three films and in the television series and was loosely inspired by Leopold Stokowski and Albert Einstein. He is also voiced by Dan Castellaneta in the animated sections of the television series.
In Back to the Future, he introduces Marty McFly to the DeLorean time machine that he invented, which results in Marty being accidentally transported back to the year 1955. He returned alongside Marty in Back to the Future Part II, in which they travel into the future to 2015. In Back to the Future Part III, he is accidentally transported back to 1885 and there builds another time machine using a steam engine locomotive.
Emmett Brown has been ranked by critics as one of the greatest film characters of the 1980s and is regarded as Lloyd's most memorable film role. He was listed by Empire as one of the greatest film characters of all time.
