Just in case you missed this reprint of the 1947 article about C.S. Lewis in Time:
The lecturer, a short, thickset man with a ruddy face and a big voice, was coming to the end of his talk. Gathering up his notes and books, he tucked his hornrimmed spectacles into the pocket of his tweed jacket and picked up his mortarboard.
Still talking—to the accompaniment of occasional appreciative laughs and squeals from his audience—he leaned over to return the watch he had borrowed from a student in the front row. As he ended his final sentence, he stepped off the platform.
The maneuver gained him a head start on the rush of students down the center aisle. Once in the street, he strode rapidly —his black gown billowing behind his grey flannel trousers—to the nearest pub for a pint of ale.
Clive Staples Lewis was engaged in his full-time and favorite job—the job of being an Oxford don in the Honour School of English Language & Literature, a Fellow and tutor of Magdalen College and the most popular lecturer in the University. To watch him downing his pint at the Eastgate (his favorite pub), or striding, pipe in mouth, across the deer park, a stranger would not be likely to guess that C. S. Lewis is also a best-selling author and one of the most influential spokesmen for Christianity in the English-speaking world.
Since 1941, when Lewis published a witty collection of infernal correspondence called The Screwtape Letters, this middle-aged (49) bachelor professor who lives a mildly humdrum life (“I like monotony”) has sold something over a million copies of his 15 books. He has made 29 radio broadcasts on religious subjects, each to an average of 600,000 listeners. Any fully ordained minister or priest might envy this Christian layman his audience.
