The Johnstown Flood occurred on May 31, 1889, after the failure of the South Fork Dam on the Little Conemaugh River 14 miles upstream of the town of Johnstown, Pennsylvania. A total of 2,200 people were killed and court case was opened against the members of the South Fork Fishing and Hunting Club.
Members of the Club included Andrew Carnegie and Henry Frick
This group of people which included Carnegie, did not properly maintain the dam and its structural integrity was weak causing the water to easily break through it. Although they never were found guilty, the nation knew who caused the disaster.
Similar to Andrew Carnegie, another robber baron today is Donald Trump.
