Charles Harold Berry (1889-1965) was the Gordon McKay Professor of Mechanical Engineering at Harvard University from 1935-1955. His highly-cited research focused primarily on steam power and power generation, as well as fan design, ventilation, and associated thermodynamics. His 1954 book "Flow and Fan" remains a widely refereenced text for mechanical engineers working on ventilation problems.
