About Jeeves (from Wikipedia):
Jeeves (born Reginald Jeeves, nicknamed Reggie) is a fictional character in a series of comedic short stories and novels by English author P. G. Wodehouse. Jeeves is the highly competent valet of a wealthy and idle young Londoner named Bertie Wooster. First appearing in print in 1915, Jeeves continued to feature in Wodehouse’s work until his last completed novel Aunts Aren’t Gentlemen in 1974, a span of 60 years.
Both the name “Jeeves” and the character of Jeeves have come to be thought of as the quintessential name and nature of a manservant, inspiring many similar characters as well as the name of an Internet search engine, Ask Jeeves, and a financial-technology company. A “Jeeves” is now a generic term as validated by its entry in the Oxford English Dictionary.
Jeeves is a valet, not a butler; that is, he is responsible for serving an individual, whereas a butler is responsible for a household and manages other servants. On rare occasions he does fill in for someone else’s butler. According to Bertie Wooster, he “can buttle with the best of them”.
