Leonard Lanson Cline (11 May 1893-15/16 January 1929) was an American novelist, poet, short story writer, and journalist.
Born in the United States in Bay City, Michigan, he attended the University of Michigan, was married in 1913, published his first book of poetry, Poems, in 1914 and worked for The Detroit News from 1916 until 1922. In 1922 he began a job with the newspaper Baltimore Sun.
His writings were published in a variety of magazines: The New Republic, The American Mercury, The Smart Set, The Nation and Scribner's Magazine. His journalist work was published in the Baltimore Sun, The New York World, The Chicago Daily News, The New York Herald Tribune, and St. Louis Post-Dispatch.
The Viking Press published his first novel, God Head in 1925. It deals with the Kalevala legends in a modern society. The critic Laurence Stallings wrote: "It is the most tempestuous novel of many seasons. It would be eminently fair to believe that Leonard Cline could write rings around a half dozen of our ten best novelists." (The New York World, 21 October 1925)
In 1926 he published the humorous novel Listen, Moon!, which deals with a professor assuming the role of a pirate along the Chesapeake. Time’s reviewer wrote of it, "the commonplace has suddenly, with sublime and innocent vulgarity, comic pedantry, unflagging ebullience, gone stark, raving romantic.... The contrasting humor and whimsy of [Cline’s] new novel is as astonishing as it is joyous."
