Leo Markun

Leo Markun (1901–1932) was a writer, compiler, and editor associated with Emanuel Haldeman-Julius’s Little Blue Books, the inexpensive booklet series published in Girard, Kansas. He produced short works on subjects ranging from scientific and geographical reference to American history, statistics, psychology, crime, marriage customs, and social issues.

Markun was also involved in editorial and translation work, including editions of writings by Max Nordau and Gotthold Ephraim Lessing. His bibliography includes A Dictionary of Scientific Terms, The Psychology of the Criminal, Strange Marriage Customs, A Dictionary of Contemporary Authors, and Max Stirner and the Philosophy of the Individual.

Although few personal details about his life have survived, his substantial output made him one of the more prolific contributors to the Little Blue Book series before his death in 1932.
