Arthur Ernest Morgan was a civil engineer, U.S. administrator, and educator. He was the design engineer for the Miami Conservancy District flood control system and oversaw construction. He served as the president of Antioch College between 1920 and 1936. He was also the first chairman of Tennessee Valley Authority from 1933 until 1938 in which he used the concepts proven in his earlier work with the Miami Conservancy District.

The Miami Conservancy District is a river management agency operating in Southwest Ohio to control flooding of the Great Miami River and its tributaries. It was organized in 1915 following the catastrophic Great Dayton Flood of the Great Miami River in March 1913, which hit Dayton, Ohio particularly hard. Designed by Arthur Ernest Morgan, the Miami Conservancy District built levees, straightened the river channel throughout the Miami Valley, and built five dry dams on various tributaries to control flooding. The district and its projects are unusual in that they were funded almost entirely by local tax initiatives, unlike similar projects elsewhere which were funded by the federal government and coordinated by the U.S. Army Corps of Engineers.
