Who was responsible for creating high schools?

The establishment of high schools in the United States is largely attributed to the educational reforms of the 19th century, particularly the work of educators like Horace Mann and the influence of the common school movement. Mann advocated for universal public education, which led to the development of secondary schools to provide more comprehensive education. The first public high school, Boston Latin School, was founded in 1635, but the modern high school system evolved in the late 1800s and early 1900s, influenced by various educational leaders and societal demands for a more educated workforce.
