Venerable Augustus Tolton (1854–1897) was the first recognized African American Catholic priest in the United States. Born into slavery on April 1, 1854, in Brush Creek, Missouri, he escaped to freedom with his mother and siblings during the Civil War, settling in Quincy, Illinois. Despite facing significant racial prejudice, Tolton pursued his vocation to the priesthood, eventually studying in Rome due to the lack of acceptance in American seminaries. He was ordained on April 24, 1886, at the Basilica of St. John Lateran.

After his ordination, Father Tolton returned to the United States, ministering first in Quincy and later in Chicago, where he founded St. Monica's Catholic Church as a national parish for Black Catholics. Known for his eloquent sermons, deep devotion, and pastoral care, he attracted both Black and white congregants, challenging the racial barriers of his time. He tirelessly served his community until his untimely death from heatstroke on July 9, 1897.

In recognition of his virtuous life, Pope Francis declared Father Tolton "Venerable" on June 11, 2019, acknowledging his heroic virtues and advancing his cause for canonization.

Reflecting on his legacy, Cardinal Francis George remarked, "Father Tolton's story represents the long and rich history of African-American Catholics, who have lived through troubling chapters and setbacks in our common American history."
