Abraham Jay-Jedediah "Abe" Simpson, often known simply as Grampa, is a fictional character in the animated television series The Simpsons. Voiced by Dan Castellaneta, he is 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 World War II veteran and former farmer 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. Grampa Simpson is the father to Homer Simpson, father-in-law to Marge Simpson and grandfather to siblings Bart, Lisa and Maggie. Grampa has also fathered two illegitimate children; a daughter named Abbie by a British woman named Edwina while in the United Kingdom during World War II, and Herbert Powell by a carnival prostitute. Grampa has an older brother named Cyrus, who lives in Tahiti and has multiple native wives. He also has a younger brother named Chet, who owns an unsuccessful shrimp company. Grampa was briefly married to Amber, the same woman Homer married on a drinking binge in Las Vegas. Grampa has also been briefly married to Marge's sister, Selma Bouvier, though Homer was against it, and was once romantically linked to Marge's mother, Jacqueline Bouvier. Abe Simpson is currently married to Rita LaFleur.
