the move was Dr. Joseph Samuel Clark, an African-American leader from Baton Rouge, who previously led Baton Rouge College and the Louisiana Colored Teachers Association. In 1921, the Louisiana Constitutional Convention authorized the reorganization and expansion of Southern University; Legislative Act 100 of 1922 provided that the institution be reorganized under the control of the State Board of Education. Clark continued to preside over Southern University during its resulting expansion. Student enrollment grew from 47 to 500, and two of the school's early buildings were built during this time. The Southern University Laboratory School System began operating in September 1922. The Laboratory School was first accredited by the Southern Association of Colleges and Schools in 1936 and has conferred more than 5,000 high school diplomas since its inception. Clark presided until his retirement in 1938. Clark's son Dr. Felton Grandison Clark was appointed as president that year. He had been serving as a dean at Southern since 1934. The State School for the Negro Deaf and Blind was established here in 1938, under supervision of Southern University. In 1943, the university was visited by the First Lady, Eleanor Roosevelt. F. G. Clark generated much more expansion of the university: 33 of 114 current buildings were erected during his 30 years of tenure. The student enrollment grew from 500 to nearly 10,000 students by the end of his tenure. Under segregated state education, LSU Law School had refused to admit Charles J. Hatfield, III, an African American college graduate who filed a lawsuit in 1946 to gain professional education in the state. A special Louisiana Convention established a law program in 1947 at Southern University; it is now known as the Southern University Law Center. F. G. Clark expanded affiliated centers for Southern University, founding Southern University at New Orleans (SUNO) (1956) and Southern University at Shreveport (SUSLA) (1964). They were officially incorporated by the legislature into the Southern University System in 1974. In 1969, Clark retired and Dr. G. Leon Netterville was selected as president. On November 16, 1972, in a second day of protests as students argued to be included in determining administration policies and decisions, Denver Smith and Leonard Brown were shot during a protest outside the Old Auditorium (now the Southern University Museum of Art). The murders have never been solved, but the students were killed with buckshot, which the sheriff's deputies were using. These two students
