Msgr. Quinn (1888-1940), who was an Irish-American, was known for his fight against racial injustice.
He was a visionary and the driving force behind the establishment of St. Peter Claver Church in Bedford-Stuyvesant in 1922 — the first church in the diocese to serve a black congregation. He also founded the Little Flower House of Providence, an orphanage that cared for many children in Wading River, Long Island.
