Henry Herbert Knibbs (1874 - 1945)

Henry Herbert Knibbs was an American author and poet. He never worked as a cowboy, but he wrote western short stories, novels and poems and spent two years hoboing in the American Midwest. Knibbs's career as a Western writer came to a sudden halt when he mistakenly gave the period of a mare's gestation as nine months in a story published in the Saturday Evening Post. He certainly knew that the correct period was 11 months, but this slip of the pen cost him his writing career, as he was never able to get another piece published.
