At 7:18 a.m. on July 24, 1915, the crew of the Great Lakes excursion steamer Eastland prepared for that morning's journey and hauled in its gangplank, forcing a tardy passenger to leap aboard from the wharf along the Chicago River.
Despite the cool, damp weather, 2,573 passengers and crew crowded aboard the Eastland, the atmosphere festive. The latecomer, E.W. Sladkey, headed to the promenade deck to join coworkers from the Western Electric Company's Hawthorne Works factory in nearby Cicero. The Eastland was one of five vessels chartered to carry Western Electric workers and their families on a day-long outing from downtown Chicago to a park 38 miles across Lake Michigan to the southeast. More than 7,000 tickets had been sold.
