History
Ryan was platted by Arthur I. Flint, J. A. Thomas, and Andrew E. Anderson on August 28, 1888 within Adams Township. The city was incorporated in 1901.
On August 12, 1974, an F4 tornado swept through Ryan, destroying much of the southern part of the community, and injuring 12 people. The tornado severely damaged homes as well as Great Plains Lumber Company, St. Patrick's Catholic Church, and the West Delaware grade school. It was estimated that the tornado caused $2.5 million in damage.
Since the Iowa Highway 13 bypass was constructed, the city has annexed a small portion of land east of Adams Street (which follows the township line) from Hazel Green Township.
