Inventors and Scientific Discoveries

Frederick W. Taylor conducted the pig iron experiments at Bethlehem Steel Company (1899) as part of his scientific management studies. Taylor's work analyzed how workers could maximize pig iron loading efficiency through task specialization, rest periods, and incentive-based pay. Robert Owen pioneered worker welfare, Chester Barnard studied executive functions and acceptance theory, and Mary Parker Follett developed participative management concepts.
