# Omega Tau Sigma

Omega Tau Sigma (ΩΤΣ) is an international veterinary medicine professional fraternity. It formed at the University of Pennsylvania School of Veterinary Medicine in 1906.

## History

Omega Tau Sigma was founded by several students in veterinary medicine at the University of Pennsylvania School of Veterinary Medicine in Philadelphia, Pennsylvania in 1906. Its purpose is to encourage and foster "the development of well-rounded, ethical veterinarians and through them creates a better profession based on friendship, cooperation, and respect for their fellow professional." Its charter members were Howard H. Curtis, Gerrit P. Judd, William A. Haines, Frank E. Lentz, E. A. Parker Jr., and George A. Schwartz.
It soon opened additional chapters at other colleges of veterinary medicine. In 1911, Beta chapter was established at the New York State College of Veterinary Medicine at Cornell University in Ithaca and Gamma at the Ohio State University College of Veterinary Medicine. The fraternity went international in 1914 with the chartering of Delta chapter at Ontario Veterinary College on the campus of University of Guelph in Guelph, Ontario. It eventually spread to fifteen veterinary schools in the United States along with the branch in Canada.
The first meeting of its governing body, the Grand Chapter, was held on April 1, 1911, in Philadelphia. Today, the Grand Chapter meets annually in October.
Omega Tau Sigma was previously affiliated with the Professional Fraternity Association. The Gamma chapter went coed in 1982.

## Symbols

The Omega Tau Sigma coat of arms was developed by the Beta chapter in 1924. It features a navy blue shield with insignia, letters, and other elements in gold. The animal kingdom is represented by a lion and ram on the left and right of the shield, respectively. Behind the shield are a crossed sword and spear, representing the tools veterinarians use to defend the animal kingdom. The crest is a helmet with plumes, representing a sign of high royalty.
The fraternity's badge is a diamond-shaped yellow gold pin with a black diamond in the center that bares the Greek letters ΩΤΣ. Its pledge pin is a circular-shaped with a small square inside a larger square on a black background. The fraternity's recognition pin consists of the Greek letters ΩΤΣ.
The colors of Omega Tau Sigma are maroon and navy blue. The fraternity adopted the white carnation as its flower on April 29, 1949; the choice came from the Zeta chapter's annual White Carnation Ball. Its jewel is the pearl. Its publication is called Shroud.
