I discovered this neat little tidbit on The Rutherford B. Hayes Presidential Center

Even before he was president, Rutherford B. Hayes envisioned where technology would take the United States. In 1851 Hayes was a passenger on the first train to operate between Cincinnati and Dayton. He described the experience in a letter to his future wife Lucy Webb and, demonstrating his propensity for forward thinking, predicted air travel:

Sept. 19, 1851 – I went to Dayton yesterday and back celebrating the completion of the railroad which makes Dayton a suburb of Cincinnati. Only two hours and a half to Dayton! Shades of departed coaches “buses,” and canal boats, hide forever your diminished heads! The ‘iron-horse’ has taken away your occupation, to keep it until aerial ships take it away!

Although Rutherford B. Hayes was a man of the 19th Century, his attitude toward innovation and willingness to embrace its potential reflect an individual whose thinking extended far beyond his time.
