Patrick John Brown was born on 9 November 1952 in Oak Park, Illinois, the eldest of three children of John Brown, an FBI agent, and his wife Ruth, a music teacher. A year later his father was transferred and the family moved to Queens Village, New York.
At 17, with his father's signature on the waiver, he enlisted in the United States Marine Corps. He served from 1969 to 1973, including service in Vietnam, and rose to sergeant. After his discharge he joined the city's Fire Patrol, and in 1977 he was appointed to the New York City Fire Department.
He served with Ladder 26 in Harlem and then with Rescue 1 and Rescue 2, and became one of the most decorated firefighters in the department, with five medals on Medal Day between 1981 and 1988 for rescues from fire escapes, rooftops and burning apartments. He was promoted to lieutenant in 1987 and to captain in 1993. On 14 May 1991, leading Rescue 1 at a fire on the twelfth floor of 723 Seventh Avenue near Times Square, he set up two rope rescues from the roof that brought two trapped people to safety. In October 2000 he took command of Ladder 3.
Off duty he boxed, held a black belt in karate and taught self-defense to the blind, ran marathons, practised yoga and helped others find the sobriety he had found himself.
On 11 September 2001, Captain Brown led Ladder 3 into the North Tower of the World Trade Center. At 9:21 a.m. he reported from the 35th floor that there were many burned civilians and that his company was still heading up. After the South Tower fell and the order came to get out, he answered that he was on the 44th floor with too many burned people and would not leave them. He and ten other men of Ladder 3 were killed when the North Tower came down. He was 48.
His remains were recovered on 14 December 2001, and his ashes were scattered in Central Park at a spot he had chosen. His name is on Panel S-8 of the South Pool at the National September 11 Memorial, and the walkway in East River Park between East 14th and East 18th Streets is named Captain Patrick J. Brown Walk.
