The Past Lives of Alcatraz — 12 Moments You Probably Don’t Know

Alcatraz Island (San Francisco, CA)

Most prison tales start with a breakout, but Alcatraz began as a fort and lighthouse before it became America’s toughest federal pen.

No one ever escaped from the prison. Well, almost. And it played a part in Native American resistance.

Here’s more about that plus other interesting facts about “The Rock.”

1. Home to the First Lighthouse on the West Coast

In 1850, as gold fever gripped San Francisco, President Millard Fillmore designated Alcatraz a military reservation.

The Army saw potential in the 22-acre sandstone outcrop rising from the bay. Workers began reshaping the island in 1853, battling fierce winds and isolation.

Many laborers quit for gold prospecting, slowing construction. On June 1, 1854, keepers lit the tower’s oil lamp, creating the West Coast’s first operational lighthouse.

2. Where 100+ Cannons Stood at the Ready

Army engineers transformed Alcatraz into a fortress bristling with artillery by 1859.

They built thick walls of brick and stone, cut tunnels through solid rock, and placed gun positions to sweep the bay’s entrance.

Laborers installed 85 heavy cannons by 1861, increasing to 111 at the war’s peak.

A massive 15-inch Rodman gun joined the arsenal in 1864, capable of firing a 450-pound shell over two miles.

The fort needed constant supplies ferried from the mainland.

Soldiers hauled thousands of pounds of gunpowder, cannonballs, and provisions up the steep hillsides to stock the island’s magazines and barracks.

3. The First Prisoners of Alcatraz

Military prisoners began arriving on Alcatraz as early as 1859, housed in the damp basement of the guardhouse.

Most were Army deserters, thieves, or soldiers who couldn’t follow orders. During the Civil War, the cells filled with Confederate prisoners and local Southern sympathizers.

Guards crammed the growing population into every available space. In 1867, the Army built a dedicated brick jailhouse with proper cell blocks.

By 1868, the island officially became a long-term military prison, shifting from defense to detention as its primary mission.

4. Alcatraz & the Colonel Who Refused the Confederacy

When the Civil War erupted in April 1861, Colonel Albert Sidney Johnston commanded the Department of the Pacific.

Though Southern-born, Johnston defied Confederate supporters’ hopes that he would surrender San Francisco’s defenses.

Instead, he dispatched 10,000 muskets and 150,000 ammunition cartridges to Alcatraz.

Johnston was quoted as saying he would “defend the property of the United States with every resource at my command, and with the last drop of blood in my body. Tell that to our Southern friends!“

By 1863, when Confederate sympathizers attempted to outfit the schooner J.M. Chapman as a privateer, Alcatraz stood ready.

Federal authorities seized the vessel, arresting the crew and uncovering their planned attacks on Pacific shipping.

5. The 19 Hopi Men Didn’t Want to Give Up Their Children

On January 1895, nineteen Hopi men from Arizona arrived in chains at Alcatraz.

Their crime? Refusing to let government agents take their children to distant boarding schools.

U.S. officials branded them ‘hostiles’ for resisting policies designed to destroy Hopi culture.

The San Francisco Call newspaper mistakenly identified them as ‘murderous-looking Apache Indians’ and claimed they would stay imprisoned until they ‘learned to appreciate the advantage of education.’

For seven months, these men endured the Lower Prison’s deplorable conditions, suffering from poor ventilation, inadequate sanitation, and separation from their families during important ceremonial seasons.

They returned to Arizona on August 7, 1895, where the Hopi continued their quiet resistance against forced assimilation.

6. World’s Largest Concrete Building Rises on the Rock

In 1909, the Army began transforming Alcatraz with massive new construction.

Engineers demolished the old Citadel down to its first floor, then used that foundation to support a modern concrete cellblock designed by Major Reuben Turner.

Hundreds of military prisoners provided the labor, mixing and pouring tons of concrete reinforced with steel bars.

When completed in 1912, the three-story structure stood as the world’s largest reinforced concrete building. This imposing gray fortress contained over 600 cells, each just 5 feet wide by 9 feet deep.

The hard concrete walls absorbed sound and held the damp cold of the fog-shrouded bay, creating an atmosphere of complete isolation.

7. Capone Plays Banjo While His Brain Deteriorates

When Al ‘Scarface’ Capone arrived on August 22, 1934, he found Alcatraz far different from his cushy Atlanta prison experience.

The former Chicago mob boss, serving time for tax evasion, entered as prisoner #85.

Guards placed him in B-block, cell 181, where he lived in the same 5×9-foot space as every other inmate. Capone petitioned to join the prison band, eventually earning permission to play banjo during Sunday concerts.

Meanwhile, untreated syphilis was destroying his brain.

Fellow inmates watched his mental decline, noting his confused conversations with invisible people and unpredictable behavior swings from model prisoner to raging inmate.

8. The Birdman that Never Had Birds

Robert Stroud arrived at Alcatraz in 1942, already famous from his 17 years studying canaries at Leavenworth prison.

Reporters had dubbed him the ‘Birdman,’ but the nickname proved ironic, because Alcatraz Warden James Johnston banned birds from his prison.

Stroud had earned his transfer to Alcatraz through violence and manipulation.

After murdering a guard in 1916, he received a death sentence that President Wilson commuted to life imprisonment.

At Leavenworth, he published two books on bird diseases while continuing to clash with authorities. During his 17 years on Alcatraz, Stroud spent most of his time in isolation, studying law books instead of birds.

Fellow inmates described him as intelligent but deeply disturbed and dangerous. Nothing like the gentle character portrayed by Burt Lancaster in the 1962 film.

9. The Bay’s Cold Waters Claimed Desperate Swimmers

Alcatraz earned its reputation as escape-proof largely thanks to San Francisco Bay itself. The frigid water averaged 53°F, cold enough to cause hypothermia within 30 minutes.

Powerful tidal currents reaching 6 knots swept around the island, potentially dragging swimmers toward the Pacific Ocean.

Guards maintained that the 1.25-mile swim to shore was impossible.

They didn’t bother manning the shoreline at night, relying on the deadly water as their most effective barrier. Despite the dangers, desperate inmates still tried.

Of the 36 men involved in 14 escape attempts during the federal prison years, six were shot, two drowned, and 23 were captured.

Five disappeared into the bay, officially listed as ‘missing and presumed drowned.’

10. A Three-Day Battle That Resulted in Bloodshed

On May 2, 1946, inmate Bernard Coy squeezed his greased body through cell-block bars he’d slowly bent using stolen spoons.

He overpowered a guard, seized weapons, and freed five accomplices, igniting what became known as the ‘Battle of Alcatraz.’

Their escape plan collapsed when they couldn’t find the key to the recreation yard.

Rather than surrender, they took nine guards hostage and barricaded themselves in a cellblock, demanding safe passage from the island.

For three violent days, they fought against authorities. The standoff ended when Marines stormed the prison, using grenades and rifle fire to retake control.

Two officers and three inmates died in the bloodiest episode in Alcatraz history.

11. The Dummy Heads That Fooled the Guards

On the night of June 11, 1962, Frank Morris and brothers John and Clarence Anglin vanished from their cells.

When guards peered in during routine checks, they saw what appeared to be three sleeping men.

The next morning, officers discovered the truth. The ‘sleeping inmates’ were actually ingenious dummy heads made from toilet paper, soap, and real hair from the prison barbershop.

The convicts had spent months digging through their cell walls using metal spoons from the mess hall.

They escaped through utility corridors, climbed pipes to the roof, descended to the shoreline, and launched a homemade raft constructed from raincoats.

Despite an extensive manhunt, the three were never found, leaving behind America’s most enduring prison mystery.

12. The Quiet Final Day of Alcatraz Penitentiary

After 29 years housing America’s most notorious criminals, Alcatraz Federal Penitentiary shut down on March 21, 1963.

Attorney General Robert Kennedy announced the closure, citing runaway costs rather than security concerns.

The harsh salt air had severely corroded the concrete buildings, requiring an estimated $5 million in repairs ($47 million today).

Each prisoner cost nearly three times more to house than inmates at other federal facilities. $10 daily versus the average $3.

The prison’s final day was surprisingly ordinary. Guards escorted the last 27 inmates to the dock, where they boarded the boat to San Francisco wearing civilian clothes.

The Rock’s era as America’s most feared prison address had ended without ceremony.
