One of my favorite, for the simplicity and pure enjoyment of it, was Vladimir Nobokov. I came to know of and read Nobokov after I read a 1990s interview with actor Tim Curry saying he was reading a short story book by the author.
Here's how Nabokov's routine rolls out:
After waking up between six and seven in the morning, I write till ten-thirty, generally at a lectern which faces a bright corner of the room instead of the bright audiences of my professorial days. The first half- hour of relaxation is breakfast with my wife around eight-thirty, and the creaming of our mail. One kind of letter that goes into the wastepaper basket at once, with its enclosed stamped envelope and my picture, is the one from the person who tells me he has a large collection of autographs (Somerset Maugham, Abu Abdul, Karen Korona, Charles Dogson Jr., etc.) and would like to add my name, which he misspells. Around eleven, I soak for 20 minutes in a hot bath, with a sponge on my head and a wordsman’s worry in it, encroaching, alas, upon the nirvana. A stroll with my wife along the lake is followed by a frugal lunch and a two-hour nap, after which I resume my work until dinner at seven. An American friend gave us a Scrabble set in Cyrillic alphabet, manufactured in Newtown, Conn.; so we play skrebl for an hour or two after dinner. Then I read in bed—periodicals or one of the novels that proud publishers optimistically send us. Between eleven and midnight begins my usual fight with insomnia. Such are my habits in the cold season. Summers I spend in the stumbling pursuit of lepidoptera on flowery slopes and mountain screes; and, of course, after my daily hike of fifteen miles or more, I sleep even worse than in winter. My last resort in this business of relaxation is the composing of chess problems. The recent publication of two of them (in the Sunday Times and The Evening News of London) gave me more pleasure, I think, than the printing of my first poems half a century ago in St. Petersburg.
