At the end of 2006 , the Delta Chapter of Delta Zeta at DePauw University became enmeshed in a controversy that would eventually make national headlines and result in the chapter ' s closure . The Delta Zeta national leadership was criticized after the New York Times published an article accusing the National office of moving certain members of the Delta Chapter at DePauw University to alumnae status based on their perceived attractiveness . Founded in 1909 , the Delta chapter was the sorority ' s second oldest active chapter and its fourth oldest chapter overall ( a " single letter " chapter ) . Despite its long history at DePauw , the Delta chapter struggled with declining membership and had acquired a negative reputation on campus . As a result , the Delta chapter members voted to request Delta Zeta Sorority to close the chapter due to falling numbers and lack of interest in recruitment . When notified of the chapter decision , Delta Zeta Sorority arranged a chapter membership review and chapter reorganization rather than close the chapter completely . Several of the members that were moved to alumnae status ( and therefore required to move out of the Delta Zeta house at DePauw ) argued that they were moved to alumnae status due to their perceived unattractiveness , weight , or ethnicity and contacted the media .
