Sigma Delta Chi, known today as the Society of Professional Journalists, was founded at the university in 1909 by a group of student journalists, including Eugene C. Pulliam. The world's first Greek-letter sorority, Kappa Alpha Theta, was also founded at DePauw in 1870. DePauw is home to the two longest continually running fraternity chapters in the world: the Delta chapter of Beta Theta Pi and the Lambda chapter of Phi Gamma Delta.[9]
