Abraham Simpson

Abraham Jay "Abe" Simpson, often known simply as Grampa, is a fictional character in the animated television series, The Simpsons. He is voiced by Dan Castellaneta and he is also the patriarch of the Simpson family, the father of Homer Simpson, and the grandfather of Bart, Lisa, and Maggie Simpson. In the 1000th issue of Entertainment Weekly, Abe was selected as the Grandpa for "The Perfect TV Family. Abe is a veteran of both World War I (by enlisting as a toddler) and World War II, who was later sent to the Springfield Retirement Castle by Homer. He is known for his long, rambling stories and incompetence. He shares his name with Matt Groening's grandfather. However, Groening says he refused to name him, leaving it to other writers to choose a name. By coincidence, the writers chose the name Abraham.
