Father Clark was born Charles Clark in 1901 in Pennsylvania. His family moved to Illinois. In 1919 he entered the
Jesuits (the Society of Jesus) at St. Stanislaus Seminary in Florissant and was ordained a Catholic priest in 1932. He taught at Saint Louis University High School from 1934 to 1936. During World War II, Father Clark served as an Army chaplain at Camp Bowie, Texas. Being Clark, he connected most to the soldiers who got in trouble. Clark then became a retreat leader and did parish mission work around the country. Clark was a popular speaker who packed them in with his frankness and honesty. He connected easily with the sinners, but not so much with "the good people." One day Clark found himself outside of City Jail in St. Louis. Curious, he went inside. There he found a prisoner in a cell laying in his own vomit who had been beaten into a
false confession. Charles Clark found his mission. He made more visits to City Jail and discovered more mistreatment of prisoners and injustices in the court system. In particular, he became aware of the lack of support for prisoners leaving prison. He began working full time with men in prison. Often called "Charlie," Father Clark changed his first name to Dismas to connect with ex-convicts. According to Christian tradition,
St. Dismas was the name of the Good Thief on the cross to whom Jesus promised: "Today you will be with me in paradise." As is mentioned in the movie
The Hoodlum Priest, the Good Thief is the only one in the gospels to get such a promise. ==Dismas House==
