Originally founded in 1864 at Rensselaer Polytechnic Institute, Theta Xi was the only fraternity to emerge during the Civil War. It was also the first-ever professional Greek letter organization, in that it was originally founded as an engineering fraternity. In 1926, it became a general social fraternity and began accepting prospective members with all interests and backgrounds as it continues to do today.
As of 2013, Theta Xi consists of over 50 active chapters across the United States and has initiated over 65,000 individuals who went on to become award-winning actors and screenwriters, College Football Hall of Fame members, inventors, Congressmen, Nobel laureates, and more. Among our notable alumni are steel tycoon Andrew Carnegie, Garfield creator Jim Davis, NASA astronaut James Voss, former Disneyland president Jack Lindquist, and Father of Scientific Management Fredrick Winslow Taylor.
