His relatives include: uncle Charles Silversmith and niece Queenie; uncle Cyril; uncle George; aunt Annie; an aunt, Mrs P. B. Pigott, who lives in Maiden Eggesford, Somerset; an aunt who had urges to ride in Hansom Cabs; aunt Emily (deceased); a niece, Mabel; cousin Egbert, a policeman in Yorkshire; and a cousin George.
He was privately educated, can read and write shorthand and type. He is fond of reading philosophical works, particularly by Spinoza* and the 'great Russians'. Not surprisingly, he has extensive knowledge of literature and philosophy and quotes freely, although not always accurately. He has also spent time studying jewellery with a cousin in the trade; he can tell the difference between natural and cultured pearls. He knows how to use a cosh effectively and 'dabbled' in the First World War.
In his early days in service, he was a page-boy at a school for young ladies. Later, he worked for Lord Brancaster, Lord Frederick Ranelagh, Lord Worplesdon, and Mr Digby Thistleton (now Lord Bridgenorth) and Mr Montague-Todd, both financiers. He is now valet to Bertie Wooster. He can also buttle with the best, as when he temporarily worked for Lord Rowcester and stood in for Dahlia Travers's butler when he was sick.
He frequently criticizes Bertie's dress sense, being more conservative in such matters. He is a member of the Junior Ganymede Club for valets and butlers and has contributed over 11 pages concerning Mr Wooster to the club book. He rarely exhibits any emotion, but has been known to raise an eyebrow a fraction of an inch.
He takes a summer holiday, usually two weeks shrimping in Bognor Regis, July or August, but also in Herne Bay in Kent. On more than one occasion he has left his holiday to rally round Bertie. He once judged a beauty contest in Folkestone. A keen fisherman, he 'dearly loves to flick the baited hook'.
His first appearance is told in Jeeves Takes Charge which just about sums up his first rescue of Bertie.
He had an 'understanding' with Mrs Watson, Mr Mortimer Little's cook, but engineered a break to pursue a waitress. He also made Sir Roderick Glossop think that Wooster is of unsound mind to engineer a break between Bertie and Honoria Glossop. He proved a good judge of the betting, whether horses, sermons or the egg-and-spoon race. (The Inimitable Jeeves)
He can be the 'man about town', successfully mixing with celebrities in New York night clubs. (The Aunt and the Sluggard)
He engineered Anatole's move from the Little's household to the Travers. (Clustering Round Young Bingo)
He temporarily left Mr Wooster's service for Lord Chuffnell and J. W. Stoker but readily returned after Bertie gave up the banjolele. (Thank you, Jeeves)
He sorted out Bertie's failures to bring couples together at Brinkley Court after making a mistake sending Gussie Fink-Nottle out dressed as Mephistopheles. (Right Ho, Jeeves)
He helped resolve the alliances of Gussie and Madeline Bassett and Stiffy Byng and Rev Pinker, while keeping Bertie safe from his host Sir Watkyn Bassett and Roderick Spode. (The Code of the Woosters)
He devised a scheme to help Bertie's uncle Lord Worplesdon which just happened to take them to Steeple Bumpleigh where the fishing is good. His schemes went wrong several times, not through his fault. (Joy in the Morning)
When Gussie Fink-Nottle had to pose as Bertie, Jeeves had to accompany Gussie as his (Bertie's) valet to Deverill Hall. Here he showed that he could wield a cosh with great efficiency. (The Mating Season)
He was loaned to Lord Rowcester as a butler while Bertie was at a special school learning to fend for himself. He helped his Lordship by acting as a bookie's clerk until that all went wrong when they couldn't cover a bet. (Ring for Jeeves) He performed the same services in the earlier play version of the story. (Come On, Jeeves)
Back in Bertie's employ, he helped Bertie's Aunt Dahlia in her mission to sell her paper and in doing so, Bertie to avoid Florence Craye again. (Jeeves and the Feudal Spirit)
He accompanied Bertie to a country home where he helped fake a burglary with brown paper and treacle. (Jeeves Makes an Omelette)
He gave up his holiday to help Bertie at Brinkley when it looked like there were sundered hearts to mend and couples to be kept apart. (Jeeves in the Offing)
He adopted the alias Chief Inspector Witherspoon, of Scotland Yard, to save Bertie from being arrested in Stiff Upper Lip, Jeeves.
He assisted Bertie to escape from the Greasy Bird's plot. (Jeeves and the Greasy Bird)
He has some political views, probably Conservative, and canvassed for Harold Winship in Much Obliged, Jeeves. He had canvassed twice before entering Bertie Wooster's service.
He accompanied Bertie to Maiden Eggesford where, coincidentally, one of his aunts lives. (Aunts Aren't Gentlemen)
According to Wodehouse in Bring on the Girls, Jeeves was named after a Gloucestershire cricketer Percy Jeeves, and based on a butler that PG employed for the purpose of study. The butler's name was Eugene Robinson. (Robinson and Wooster?)
