Southern University Laboratory High School, Baton Rouge Posted on September 21, 2018September 21, 2018 by africanamericanhighschoolsinlouisianabefore1970 Southern Laboratory High School was an invention of Dr. J. S. Clark and originated in 1922. The Laboratory School presently exists and thrives on its main campus. The school is noted for its scholars, athletes and alumni. The Kittens have had their share of success during the LIALO days and in the LHSAA days. The Kittens’ 1941 Year Book was added to their site page. We encourage the alumni to present more year books.
