Theta Omicron Chapter History

About Tri Delta

In 1836, a few miles from the current city of Walla Walla, Marcus and Narcissa Whitman established a medical mission and a school to serve the Cayuse Indians and immigrants on the Oregon Trail. After the Whitmans were killed by Indians in 1847, Rev. Cushing Eells resolved to establish a school in the Whitmans' honor. The Washington Territorial Legislature granted a charter to Whitman Seminary on December 20, 1859. On November 28, 1883, the legislature issued a new charter, changing the seminary into a four-year, degree-granting college. Text courtesy of Whitman College,

In the early 20th century, a women's group called Wakelita formed on the Whitman College campus. Originally organized as a social group, the women of Wakelita decided to become a local sorority and petition for membership in a national organization. Wakelita became the local sorority Sigma Gamma in 1919, and the women began a quest for a larger organization with values similar to theirs.

Many of Whitman's men were called to fight in World War I, including many men from Phi Delta Theta. To help maintain their house, Phi Delta Theta sectioned off part of it and allowed Sigma Gamma to live there. This is also recorded in the history of Washington Beta Chapter of Phi Delta Theta, available at The women of Sigma Gamma chose to affiliate with Delta Delta Delta during this time and began the process of petitioning for membership. Helped by the men of Phi Delta Theta, Sigma Gamma produced an excellent petition and was granted a charter. From January 18-21, 1923, Theta Omicron Chapter of Delta Delta Delta was installed at Whitman College.

After eighty-two years on the Whitman College campus, Theta Omicron chapter has been closed by the Tri Delta Executive Office. Our closing date was May 10, 2005.
