Abraham Jay-Jedediah "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, Grampa was selected as the Grandpa for "The Perfect TV Family".
Grampa 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, often incoherent 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.
Homer Jay Simpson is a fictional character who appears in the animated television series The Simpsons as the patriarch of the eponymous family. He is voiced by Dan Castellaneta and first appeared on television, along with the rest of his family, in The Tracey Ullman Show short "Good Night" on April 19, 1987. Homer was created and designed by cartoonist Matt Groening while he was waiting in the lobby of James L. Brooks' office. Groening had been called to pitch a series of shorts based on his comic strip Life in Hell but instead decided to create a new set of characters. He named the character after his father, Homer Groening. After appearing for three seasons on The Tracey Ullman Show, the Simpson family got their own series on Fox that debuted December 17, 1989.
Homer and his wife Marge have three children: Bart, Lisa, and Maggie. As the family's provider, he works at the Springfield Nuclear Power Plant. Homer embodies several American working class stereotypes: he is crude, overweight, incompetent, clumsy, lazy, a heavy drinker, and ignorant; however, he is essentially a decent man and fiercely devoted to his family. Despite the suburban blue-collar routine of his life, he has had a number of remarkable experiences.
