Sam Houston State University, (known as SHSU or Sam) was founded in 1879 and is a public university located in Huntsville, Texas. It is one of the oldest purpose-built institutions for the instruction of teachers west of the Mississippi River and the first such institution of its type in the State of Texas. It is named for one of Texas' founding fathers, Sam Houston, who made his home in the city. The university is part of the Texas State University System and is a comprehensive, doctoral granting university enrolling approximately 16,000 undergraduate and graduate students. The University is ranked as a Doctoral Research University by the Carnegie Commission on Higher Education and is the only university classified as such within the Texas State University System. Created by legislation signed by Governor Oran M. Roberts on April 21, 1879, Sam Houston Normal Institute's dedicated goal was to train teachers for the public schools of Texas—the first of its kind in the southwestern United States. On October 10 of the same year, the first class of 110 students and four faculty commenced instruction on the site of what had once been the campus of Austin College. When the university first opened, students received a certification to teach in the state's elementary and secondary schools, but after 1919, the university began to award bachelor's degrees. In 1936, the school awarded its first post-baccalaureate degree. The university celebrated its 125th year in 2004.
