Perhaps the person who is most responsible for making Casey at the Bat one of the most beloved and well-known poems in American history is the actor and singer DeWolf Hopper (1858-1935). Hopper, who had a booming voice, first recited the poem on August 18, 1888, on Thayer’s 25th birthday. It is said he ultimately performed the poem 10,000 times, often as an encore to a stage presentation. He also recorded a phonograph version.
One of the earliest recordings of Hopper’s recitation available on the internet is from June 16, 1909, in New York, USA.
