George Cooper wrote hundreds of poems, including “The Wind and the Leaves,” “Only One Mother,” and “October’s Party.” Today he is remembered primarily for his collaboration with Stephen C. Foster, with whom he wrote more than twenty songs, including war songs, such as “For the Dear Old Flag I Die!”, and comedic music hall songs, such as “There Are Plenty of Fish in the Sea.” In his lifetime, his most popular song was “Sweet Genevieve” (1869), which was set to music by Henry Tucker. “Sweet Genevieve” experienced a revival in the early twentieth century, which, according to his obituary, earned Cooper substantial royalties in the years before his death in 1927. From 1930 to 1958 “Sweet Genevieve” appeared in at least 27 films.
