Leonid Nikolaievich Andreyev (21 August [O. S. 9 August] 1871 - 12 September 1919) was a Russian playwright, novelist and short-story writer, who is considered to be a father of Expressionism in Russian literature. He is regarded as one of the most talented and prolific representatives of the Silver Age period. Andreyev's style combines elements of realist, naturalist, and symbolist schools in literature. Of his 25 plays, his 1915 play He Who Gets Slapped is regarded as his finest achievement. Often referred to as 'a Russian Edgar Allan Poe', Andreyev had an influence through translations on two of the great horror writers, H. P. Lovecraft and R. E. Howard. Copies of his The Seven Who Were Hanged and The Red Laugh were found in the library of horror writer H. P. Lovecraft at his death, as listed in the "Lovecraft's Library" catalogue by S. T. Joshi. Andreyev was also one of the seven "most powerful" writers of all time, in the opinion of Robert E. Howard. (wikipedia. org)
