Elbert

Elbert Tuttle (1897 – 1996) was an American judge. He was the chief judge of the United States Court of Appeals for the Fifth Circuit from 1960 to 1967, when that court became known for a series of decisions crucial in advancing the civil rights of African Americans during the civil rights movement. A Republican from Georgia, he was among the judges that became known as the "Fifth Circuit Four". At that time, the Fifth Circuit included not only Louisiana, Mississippi, and Texas (its jurisdiction as of 2024), but also Alabama, Georgia, Florida, and the Panama Canal Zone.

Elbert was the name of Eugene's imaginary pet hippo on the episode of Hey Arnold where Arnold accidentally kills Eugene's goldfish Henry.
