“Everybody complains about the weather, but nobody does anything about it.”

Charles Dudley Warner (1829 – 1900) was an American essayist, novelist, and friend of Mark Twain, with whom he co-authored the novel The Gilded Age: A Tale of Today.
Warner travelled widely, lectured frequently, and was actively interested in prison reform, city park supervision, and other movements for the public good. He was the first president of the National Institute of Arts and Letters, and, at the time of his death, was president of the American Social Science Association. He first attracted attention by the reflective sketches entitled My Summer in a Garden (1870; first published in The Hartford Courant), popular for their abounding and refined humour and mellow personal charm, their wholesome love of outdoor things, their suggestive comment on life and affairs, and their delicately finished style.
Charles Dudley Warner is known for making the famous remark,

“Everybody complains about the weather, but nobody does anything about it.”

This was quoted by Mark Twain in a lecture, and is still commonly misattributed to Twain.
