About Delta Theta Sigma

Delta Theta Sigma is a social-professional agricultural fraternity. It was created in 1906 at The Ohio State University. There are currently eight chapters of Delta Theta Sigma. The brotherhood of Delta Theta Sigma is composed of elite agriculture majors from all over the United States. The national Delta Theta Sigma network includes eight chapters through Ohio State University, Wisconsin University, University of Minnesota, Purdue University, Wilmington College of Ohio, and Penn State University. Brothers share common interests in agriculture and outdoor recreation. A majority of the members come from farm backgrounds or rural areas, which provides common bonds through experiences.

History of Delta Theta Sigma

The Start of Delta Theta Sigma

In the spring of 1906, several men gathered together in a rooming house at 175 West 9th Avenue in Columbus, Ohio. The idea, conceived primarily by three men, Maxwell Corotius, Samuel N. Kerr, and Stanley B. Stowe, was the actual beginning of Delta Theta Sigma Fraternity at the Ohio State University. The fraternity was incorporated under the laws of the State of Ohio on April 5, 1907 with 17 charter members. The name, Delta Theta Sigma®, and the four-fold purposes of the fraternity were drafted with the advice of Professor Smith of the Greek Language Department at Ohio State University.

The Delta Theta Sigma idea was contagious, not only at Ohio State University but also on many other agricultural college campuses throughout the Midwest. Within a few years chapters had been organized on ten other campuses. At a national convention in 1912, all of the chapters except the original chapter at Ohio State University voted to make Delta Theta Sigma an agricultural honorary fraternity. The local chapter at Ohio State University retained the original name, Delta Theta Sigma. The other ten chapters, therefore, assumed the name, Gamma Sigma Delta.

New Chapters – Beta and Gamma

On November 26, 1927, representatives from Delta Theta Sigma at Ohio State University, Alpha Gamma Phi at Pennsylvania State University, and a former Farmhouse Chapter at the University of Wisconsin met in Pittsburgh, Pennsylvania in Room 211 of the William Penn Hotel. This meeting resulted in the formation of a new national agriculture fraternity, Delta Theta Sigma.

Within a two-year period from 1957-1958 all three chapters moved into new houses. Gamma Chapter at Wisconsin expanded from one house into two houses located at 320 North Lathrop Street. Beta Chapter at Pennsylvania was the victim of a costly fire during the winter of 1958. They were fortunate, however, and found an excellent house at 101 North Patterson Street, into which they moved during the spring of 1958. Alpha Chapter at Ohio State outgrew the old house and moved into a new chapter home located at 80 East 13th Avenue in March of 1958.

New Chapter – Delta

This same year, 1958, found the fraternity growing nationally, also. A fourth chapter, Delta, at the University of Minnesota, was organized and approved for membership in National Delta Theta Sigma in May 1958. During the 1960-61 school year, Delta Chapter rented their first and present chapter home located at 1485 North Cleveland Avenue. Then, in the fall of 1966 growth required they rent the downstairs of the house next door at 1495 North Cleveland Avenue.

New Chapter – Epsilon

In 1969, our fifth chapter, Epsilon, was chartered at the University of Wisconsin – River Falls. Albert Beaver, Gamma Chapter alumnus, was instrumental in organizing Epsilon, and in 1970, helped them to purchase the house in which they are presently located.

New Chapter – Zeta

Our sixth chapter, Zeta, was organized and chartered at Purdue University, West Lafayette, Indiana, in the spring of 1982. With the help of four alumni Neils Neilson, Gamma; George Van Soyoc and Jim Vorst, Alpha; and Herb Olm, Delta, the thirteen charter members and one new member, were activated by National Delta Theta Sigma officers in May 1982. Zeta was very fortunate to be able to rent a house their first year and are presently located at 321 Vine Street.

New Chapter – Eta

In January of 1983 agricultural students at Wilmington College of Ohio had a desire to belong to a national fraternity. Through the leadership of senior J. Timothy McCarty, thirty-six students were recruited and expressed desire to become founding fathers of Eta. With the direction of National Officer Rick Harr, the Eta chapter was organized and chartered in the Spring of 1983. With the help of the National Executive Council, the purchase of a large house near campus was made. The Chapter House at 780 Rombach Ave. in Wilmington was occupied in January of 1984.

New Chapter – Theta

In 1997 Delta Theta Sigma colonized the University of Minnesota-Crookston Chapter with much help from the Men of Delta Chapter. Theta was officially recognized as a chapter at the 1998 Conclave hosted by Delta Chapter. Theta Chapter is currently renting a house located at 101 North Nelson, they plan on purchasing this house in the upcoming year.
