Early life
Chicago held him from the first. Born to Irish immigrant parents in May 1859, he attended city schools and spent his boyhood watching neighborhood engine companies. Family records place his birthday on 10 May; contemporary newspaper accounts give 29 May.
In 1881, at twenty-two, he entered the department as a water-supply driver. The next quarter century is a climb without a leap — pipeman, lieutenant, captain, assistant marshal — until the city put the whole brigade in his hands. About 1886 he married Katie A. Ryan. She died in 1895 and was laid at Calvary. On 21 October 1903 he married Margaret Ellen Mahoney. Four children were living when he was killed. The house stood at 722 Ashland Avenue, near Twelfth Street, later Roosevelt Road. He was a Catholic and a Knight of Columbus.
Iroquois, 1903
In late December 1903, Horan was Third Assistant Fire Marshal. When the Iroquois Theatre burned on 30 December, he was among the first senior commanders to enter the building, directing rescue operations in the balconies. The fire took 602 lives and prompted widespread theater safety reforms.
Chief, 1906–1910
Mayor Edward Dunne named him Fire Marshal in 1906, after John Campion. He was forty-seven. Mayor Fred Busse kept him the next year. Campion had followed William H. Musham; Musham is an earlier chief, not Horan’s predecessor.
Four years of command meant new houses, new iron, and companies pushed into industrial ground. Engine Companies 101 through 117 and Truck Companies 30 through 34 were organized in that span. Merchants and insurers backed the upgrades, and a Tribune editorial praised him as an “implacable enemy of politics.” Throughout his command, Horan urged the city to fund high-pressure water mains in the Stock Yards, but the City Council adjourned each term without action.
Cherry, 1909
In November 1909 the state asked Chicago for men and gear at Cherry, Illinois. Horan went by special train with eleven veterans, Draeger oxygen helmets, deluge hose, and chemical apparatus. The Chicago squad pumped hundreds of gallons of water per minute down the burning shafts and entered the toxic galleries. Twenty-one miners were brought out alive on the seventh day. Two hundred fifty-nine miners died. The full forensic record sits on the Cherry Mine disaster event page.
Stock Yards, line of duty, 1910
On the morning of 22 December 1910 he stood before the City Council and asked again for those high-pressure mains. The Council adjourned without acting. Hours later he was dead under a packinghouse wall.
About 04:00 a watchman found fire in the hide cellar of Nelson Morris Beef Plant No. 7. Companies came. Freight cars on the siding forced long hose lays. Hydrants had been turned down against freeze. Horan took command at 05:05. With Second Assistant Fire Marshal William J. Burroughs he set lines under the wooden loading canopy at the east door. Other men climbed the canopy to hit the upper windows. The tracks left them no other platform.
Lieutenant Joseph Mackey saw the brick wall bow, gave warning, and jumped. Ten or twelve jumped with him and lived. Those under the canopy had no path. Six stories of masonry came out. The canopy went under. Horan and twenty of his men were buried. He was fifty-one. Twenty-one Chicago firefighters and three civilians died. It remains the department’s deadliest hour.
Command passed to First Assistant Charles Seyferlich. Late that night an ammonia tank blew the roof off Warehouse No. 6. Mayor Busse spent hours in the wreckage; Seyferlich pulled him clear of flying brick. Railroad derricks and steam shovels worked about seventeen hours before they uncovered the chief. CFD historian Bill Cattorini, speaking to CBS Chicago in 2010, said the body was on its knees, arms folded, facing the ruins. Margaret was first told he had been hurt. She collapsed when the recovery was named.
The complete timeline of the fire and the names of the twenty-one firefighters killed with him are recorded on the yards event page and the Fallen 21 roll.
Funeral / the men
Chicago stopped for him. Busse called the Council and named fifteen aldermen to honors and relief. On 26 December a horse-drawn caisson left the Ashland Avenue house. His white leather helmet sat on the flag. The Tribune called the cortege a civic pageant. Tens of thousands stood in the cold. Archbishop James Quigley said a Requiem High Mass at Holy Name Cathedral. They buried him at Calvary Catholic Cemetery in Evanston.
A public fund raised $211,000 for widows and children. When trustees tried to pay only interest, the widows sued and won the principal.
Burroughs died on the same canopy line. Captain Patrick E. Collins and Lieutenants Herman G. Brandenburg, Edward J. Danis, and William G. Sturm are named in the contemporary lists. All twenty-one members are commemorated on the memorial roll at the Union Stock Yard Gate. Two leather helmets later entered the Chicago History Museum, and the National Fallen Firefighters Foundation keeps Horan on its Roll of Honor.
