- ‶One wrong man can always find a friend″
Richard was married to Emily Gilmore and is the father of Lorelai Gilmore and the grandfather of Rory Gilmore. His mother, Lorelai "Trix" Gilmore, also appears in several episodes. Richard is a stern, hard-working, old-fashioned husband and father, who enjoys cigars, golfing and brandy. He rigorously adheres to the traditional life of high society, with its class structures, rules and concepts of appropriate behaviour.
He does not tolerate any form of scandal, but shows glimpses of perhaps not a really emotional attachment to the trappings of his and his wife Emily's lifestyle. While at moments throughout the show, it's obvious Richard has deep affection and admiration for his daughter, Lorelai, he adheres to the confines of his societal standing, and Emily's broken heart, and does not easily forgive Lorelai for leaving the family as a teenager.
At the start of the series, Richard is the Executive Vice President of the Gehrman-Driscoll Insurance Corporation, and he oversees their international division. He has taken on several different ventures since he was initially forced into retirement. He gets a teaching job at the Yale University where he holds lectures on economics, which are attended by his granddaughter Rory. Richard suffered a bout of angina in December 2000. He has a serious second heart attack in 2006 and undergoes a open-heart surgery that'll leave him inoperative in his job for a good number of the following episodes.
During the time that Rory stayed with Richard and Emily so that she could have a "do-over", he was the first to admit and realize that "the moment they took Rory away from Lorelai, they lost."
Through the series Richard has adored Rory for her literary taste and sweet nature. He's very protective of her; as shown when he met Dean (her boyfriend during season 2). Richard grills Dean, knowing he's not good enough for Rory. During 'Richard in Stars Hallow' Dean gave Rory a car he made himself, Richard loudly protested (against Lorelai). The two males go to Gypsy's, she finds nothing wrong but Richard makes her check it many times. Dean says he loves Rory, Richard says she's young but doesn't hate Dean, somewhat apologizes for his interrogation. He notices Dean is tall, Dean sarcastically asks if he wants a dance, Richard says "No, thank you. I appreciate the offer though."
When Rory attends Yale, a Gilmore tradition, she enters a relationship with Logan Huntzberger. Richard is happy she's with a blue-blood but grieves when he learns Rory isn't a virgin.
In Season 7, while he was teaching an Economics class at Yale, he falls and has a heart attack. He is unable to fully function at his job after that.
