The ever-efficient secretary to Mr. Drysdale, Jane Hathaway takes great pleasure in teaching the Clampetts the ways of big city life. More intelligent than her money-hungry boss, Miss Jane appreciates Jed's simple wisdom. But the prim and proper spinster is smitten with Jed's nephew, the rugged, but simple, Jethro Bodine. At times she can be so blinded by his brawn that she comes frightfully close to making a fool of herself. In the end, Miss Hathaway always manages to maintain her composure with the Clampetts while carrying out Drysdale's outrageous demands.
Though she always carried out his wishes, she was inherently decent and was frequently put off by her boss' greed. When she was annoyed with him, as was often especially when one of Drysdale's schemes went too far, she would usually and forcefully say "Chief!" Unlike Drysdale (who was merely interested in the Clampetts' wealth), Jane was genuinely fond of them (to the Clampetts, she was considered family; even Granny, the one most dead-set against living in California, liked her very much and thought of her as part of the family), in fact, she actually harbored something of a crush on Jethro for most of the series' run. At first, she mistook the Clampetts as the servants, until she realized who they really were (which almost cost her her job). Miss Hathaway frequently has to "rescue" Drysdale from his idiotic schemes, receiving little or no thanks for her efforts. In one episode, she and Granny, disguised as "geisha girls," finally have enough and "crown" Drysdale and Jethro, who have made one too many comments about women serving men. Jane is loyal to Drysdale as well, despite her misgivings toward his avarice and greed. In one episode, the Clampetts, feeling money has corrupted them, give all of their money to Jenny Jennings (Sheila Kuehl), a college student. While Drysdale moans the loss of the money, Jane immediately tells him to stop thinking about the Clampetts and start trying to get the Jennings account. Eventually, everyone discovered Jennings' real motives, and she was gone, with the Clampetts getting their money back, and things were as they were before. In one episode, it is established that Miss Jane sacrificed her job as the top secretary of the top executive of the top insurance company to join Mr. Drysdale at the Commerce Bank. Miss Jane was a Vassar graduate. Jane Hathaway appears in 246 episodes.
