WREN

It's the birthday of the man who designed St. Paul's Cathedral in London, architect Christopher Wren, born in East Knoyle, England (1632). In addition to his accomplishments as an architect, he knew Latin, he could draw, he did work in medicine and mechanics, he was a brilliant mathematician and astronomer, and a philosopher, too.
And he had impeccable manners. He particularly disliked swearing. When he was overseeing the construction of St. Paul's, he issued this official order: "Whereas, among laborers, etc., that ungodly custom of swearing is too frequently heard, to the dishonor of God, and contempt of authority; and to the end, therefore, that such impiety may be utterly banished from these works, intended for the service of God, and the honor of religion. It is ordered, that customary swearing shall be a sufficient crime to dismiss any laborer that comes to the call; and the clerk of the works, upon sufficient proof, shall dismiss them accordingly. And if any master, working by task, shall not, upon admonition, reform this profanation among his apprentices, servants, and laborers, it shall be construed his fault; and he shall be liable to be censured by the commissioners."
