Which composer is known for songs such as "Beautiful Dreamer", "Oh Susanna", and "My Old Kentucky Home"?

The songs "Beautiful Dreamer", "Oh Susanna", and "My Old Kentucky Home" are all attributed to Stephen Collins Foster, who is widely recognized as one of the first significant American songwriters. Foster's work, particularly in the mid-19th century, played a crucial role in the development of American popular music. His melodies often conveyed themes of nostalgia, life in the South, and folk culture, which resonate in the songs mentioned.

While George Gershwin, Irving Berlin, and Johnny Cash each made significant contributions to American music in their own right, they are known for different genres and time periods, with Gershwin associated with jazz and classical crossover, Berlin with Broadway and popular standards, and Cash with country music. Foster's specific focus on the folk and minstrel themes makes him the clear choice for these particular songs.
