Albert Einstein (March 14, 1879April 18, 1955) was a German-born theoretical physicist who developed the general theory of relativity, effecting a revolution in physics. Although he wasn't an actor, Einstein from Disney's 1988 movie Oliver & Company, Albert from the Disney Channel animated series Phineas and Ferb, and Albert Glass from the Disney Channel animated series Fish Hooks were named after him. Dr. Einmug specializes in atomic physics and speaks in a German-like accent which was probably a nod towards Albert Einstein. A picture of Einstein was also seen in the Timon & Pumbaa episode "Monster Massachusetts" and The Proud Family episode "Behind the Family Lines".

He was spoofed by Genie in Aladdin and the King of Thieves. In The Brave Little Toaster Goes to Mars, he was mentioned as being a former owner of the Hearing Aid who was left in a junk drawer, as well as in the Epcot attraction Ellen's Energy Adventure. In Cranium Command, when General Knowledge speaks in the pre-show and is explaining that they are different kinds of brains, he shows a picture of Albert Einstein, as the example of a person who uses his brain and Ernest P. Worrell (a popular fictional character played by Jim Varney, who was appearing in series of feature films produced by Disney at the time), as an example of the opposite. He was also mentioned in Saving Mr. Banks, an episode of I Didn't Do It, the Best Friends Whenever episode "A Time to Cheat", the BUNK'D episode "Dreams Come True" and the Bizaardvark episode "Pretty Con". He was played by Robert Towers in the Hannah Montana episode "Wherever I Go".
