The Rensselaer School was established in 1824 by Stephen Van Rensselaer "for the purpose of instructing persons ... in the application of science to the common purposes of life."
In 1833 the school became the Rensselaer Institute, and in the 1850s its purpose was broadened to become a polytechnic institution.
The Institute's name was changed in 1861 to Rensselaer Polytechnic Institute.
Rensselaer maintains an online archive of five rare books covering the Institute's early history.
Published between 1855 and 1968, the books detail Rensselaer's founding and development, and place the school in the context of scientific and technological education in the 19th and 20th centuries.
