At 7:28 on the morning of Saturday, 24 July 1915, the steamer SS Eastland — chartered by the Western Electric Company for the annual employee picnic of its Hawthorne Works plant in Cicero, Illinois — was tied at the south bank of the Chicago River between the Clark Street and LaSalle Street bridges, taking on passengers for an excursion to Michigan City, Indiana. The boat was fully booked. 2,572 picnic-goers had boarded over the preceding twenty-five minutes. They were mostly young Western Electric employees and their families: factory workers, switchboard girls, husbands, wives, children. The day was overcast but pleasant. A small band was playing on the deck.

At 7:28 the ship began to list to port. The angle increased over the next four minutes. Passengers began to slide. Furniture and pianos on the upper deck broke loose. A piano on the promenade deck slid into the river. Some passengers, sensing what was happening, leapt for the dock. Most did not have time.

At 7:32 the Eastland rolled completely onto her port side and came to rest on the muddy bottom of the river in twenty feet of water. Approximately 844 people drowned in the next several minutes, mostly inside the submerged hull, where the rapid roll and the inrush of river water gave them no time to find an exit. Twenty-two entire families were wiped out. The dead included 22 children under age 16 of a single Western Electric employee, Joseph Mioduszewski, who had brought his entire extended family for the picnic.

The river is about six feet deep on average. The ship rolled in seven feet of water at the dock. Most of the dead drowned within twenty feet of land in a depth a tall man could have stood up in.

What had gone wrong with the ship

The Eastland, built in 1903 for excursion service on Lake Michigan, had been known to be top-heavy since her commissioning. She had a history of dangerous list incidents — minor heels of fifteen or twenty degrees during ordinary maneuvering — and had been the subject of multiple regulatory inquiries. Her original design called for accommodation of 500 passengers. By 1915 her certified capacity had been raised, through a series of regulatory revisions, to 2,500.

The reason for the final, fatal instability is well-established. After the sinking of the Titanic in April 1912, the United States had passed the LaFollette Seamen’s Act of 1915, requiring all U.S.-flagged passenger ships to carry sufficient lifeboats for all aboard. The Eastland’s owners had complied, adding three additional lifeboats and six rafts to her upper deck. The added weight, all of it above the waterline, had raised the ship’s center of gravity and reduced her stability margin to approximately zero at the maximum certified passenger load. With 2,572 passengers concentrated on the upper decks (most had not yet gone below) and the river’s mild current pushing against her port side, the Eastland exceeded her stability threshold and rolled.

The post-Titanic safety regulation that had been intended to save passengers had, in this case, killed them. The Eastland’s captain, Harry Pedersen, was on the bridge throughout. He survived. He was arrested at the scene on charges of manslaughter and held briefly. The charges were dropped. He never commanded another ship.

The chief engineer, Joseph M. Erickson, had been ordered earlier that morning to take on additional ballast water in the tanks below the waterline — a standard procedure intended to lower the ship’s center of gravity and improve stability. Erickson’s later testimony to the federal inquiry was that he had taken on the ballast but that the tanks had not filled correctly due to a defect in the Eastland’s ballast system. The defect, by then well-documented, had been noted in multiple prior inspections. It had not been corrected.

Inside the hull

The rescue effort began within minutes. Tugboats from the Chicago River fleet were on the scene by 7:35. The Chicago Fire Department arrived by 7:40. Workers from the Reid Murdoch food-processing plant directly across the river ran out with ropes and ladders. Civilians dove from the dock into the river to pull people up. Most of those who were still on the upper deck or in the river when the rolling stopped survived.

Most of those trapped inside the hull did not.

The hull lay on its side in the river with the starboard hull plates above the waterline. Workers with welding torches began cutting holes through the starboard plates at about 8:00 a.m. The first survivors were pulled out by 8:15. By 9:00 the focus had shifted from rescue to body recovery. Divers worked in the muddy interior of the hull for the next three days. The Second Regiment Armory on Washington Street was requisitioned as a temporary morgue. The bodies were laid out in long rows. Families came to identify them.

The youngest victim recovered was a baby named Bobbie O’Neill, age nine months, who had been brought to the picnic by her parents. Both parents survived. They held a private funeral for the child the following Tuesday.

The oldest documented victim was a Mr. Wenzel Pikulik, age 66, who had retired from Western Electric the previous year and had come to the picnic as a guest of his son. The son also drowned. Neither was buried with the other.

The cleanup, the inquiry, and the aftermath

The Eastland was righted in three weeks. The hull was largely undamaged. The ship was sold to the U.S. Navy in 1917 for use as a training vessel. She was renamed USS Wilmette. She served as a Great Lakes naval reserve training ship until 1946, then was sold for scrap. She was broken up in 1947. The site of the breaking is in southern Illinois.

The federal inquiry, conducted by the U.S. Steamship Inspection Service through the fall of 1915, identified the design flaw in the ballast system as the proximate cause of the disaster and the post-Titanic lifeboat additions as a contributing factor. The inquiry recommended several technical revisions to passenger-ship inspection standards. Most of the recommendations were adopted. No individual was held criminally responsible. The owners of the Eastland — the Indiana Transportation Company — went bankrupt in 1917 and were unable to pay the substantial civil damages awarded against them in subsequent lawsuits. The families of the dead received, on average, settlements of under $1,000 each, paid out of the company’s residual insurance.

In Chicago, the disaster largely vanished from public memory within a generation. There was no permanent memorial at the disaster site until 1989. The current memorial — a small bronze plaque on the south bank of the river near the location of the dock — was installed by the Eastland Disaster Historical Society, an organization founded by descendants of victims. The plaque names no one specifically. It records the date, the death toll, and the words “The largest loss of life from a single shipwreck on the Great Lakes.”

The Western Electric Hawthorne Works plant in Cicero continued to operate until 1986. At its peak in the mid-twentieth century it employed 45,000 people. Generations of Chicago factory workers passed through its assembly lines. The plant kept, for decades, an internal employee newsletter that mentioned the Eastland disaster in commemorative issues every July. The newsletter ceased publication in the 1970s.

The plant itself was demolished in 1986. The site is now a strip mall. There is no plaque.
