Francis Joseph Thompson (16 December 1859 – 13 November 1907) was an English poet and Catholic mystic. At the behest of his father, a doctor, he entered medical school at the age of 18, but at 26 left home to pursue his talent as a writer and poet. He spent three years on the streets of London, supporting himself with menial labour, becoming addicted to opium which he took to relieve a nervous problem.
