Did you know Hayes is the only U.S. president to have been wounded in action during the Civil War ? (He was injured four times, most notably taking a musket ball to the left arm at the Battle of South Mountain.)

Did you know along with his wife Lucy, Hayes hosted the very first official White House Easter Egg Roll on the South Lawn in 1879, kicking off an annual tradition still held today ?

Did you know Hayes is surprisingly revered as a national hero in the South American country of Paraguay ? (After the War of the Triple Alliance, he arbitrated a land dispute between Paraguay and Argentina, ruling in Paraguay's favor and keeping 60% of their modern territory. They even named a region and a soccer club after him!)

Did you know Hayes was the first US president to use and install a telephone in the White House ? (Installed in 1877, it originally connected exclusively to the nearby Treasury Department and was assigned the phone number "1". The original phone had to be placed in the mansion's telegraph room rather than the Oval Office, as it was considered undignified for earlier executives to have a phone at their desk.)

Did you know in 1878, the U.S. consul in Bangkok gifted his wife Lucy Hayes a Siamese cat, making it the very first known Siamese cat to arrive in America ?
