Mercy Quick Facts

Mercy Heritage

  • The Sisters of Mercy were founded by Catherine McAuley, a Catholic woman, almost 200 years ago in the bleakest of societies, Dublin, Ireland. Women didn't have equal citizenship with men, a voice in government or the right to vote, and religious strife was common among Catholics and Protestants.
  • The first House of Mercy in 1927 in Dublin, Ireland. 
  • The Sisters of Mercy were among one of the world's first religious orders not to be cloistered - confined to prayer and quietness within a convent. Instead, the Sisters went out into the communities where they lived to feed the hungry, care for the sick and provide education. They were lovingly named the "Walking Sisters" because of this unique attribute.
  • The Sisters of Mercy take a fourth vow of service to the poor, sick and uneducated, in addition to the traditional three vows of all religious orders: chastity, poverty and obedience.
  • During the Crimean War, in the mid 1800s, the Sisters of Mercy worked alongside Florence Nightingale. Mercy's nursing model today was influenced by Nightingale and the care she provided alongside the Sisters of Mercy.
  • The first Mercy hospital in the world opened in Pittsburgh, Pennsylvania, in 1857.
  • In the late 1800s, the Sisters of Mercy in St. Louis worked with United Railways Company to offer its employees the first pre-paid health insurance in the country. Around the same time, the Sisters of Mercy in Joplin, Missouri, did something similar by offering care to miners for as little as 25 cents a week.
  • By the late 1800s, the Sisters of Mercy founded more schools than any other religious order in the English-speaking world.
  • The Central Bank of Ireland honored Mercy founder Catherine McAuley for her impact on Irish culture by putting her picture on a £5 note.
  • Many of the thriving hospitals built by the Sisters of Mercy began in unexpected places thanks to their foresight of how the population would shift - Mercy Hospital St. Louis was once an apple orchard and Mercy Hospital Oklahoma City was built on a cow pasture.
  • The Sisters of Mercy are currently seeking sainthood through the Roman Catholic Church for founder Catherine McAuley. She has already passed the first of three steps and has been declared venerable.
  • Sisters of Mercy Health System, which was formed in 1986, transitioned in 2011 to one name – Mercy – across four states.
