fraternity was able to expand when men returned home at the end of the war and began, or resumed, their education. By 1918 there were 14 chapters in seven states from California to New York. In 1920 the fraternity produced its first song book, The Songs of Sigma Pi. The book was produced by brothers James P. deWolfe, Herman S. Sidener, and Philip W. Timberlake. That same year the fraternity opened its first chapter in the American south with the Omicron chapter at Tulane University. Plans were first made for the creation of the Sigma Pi Foundation in 1922. The fund sold life memberships to alumni and was an endowment fund for the fraternity. Money raised was used to help chapters purchase housing and to fund other fraternity needs. Life memberships also came with a lifetime subscription to The Emerald. The fund was formally chartered in the State of Indiana on February 26, 1923. From 1920 to 1927, Sigma Pi doubled in number of chapters and established a national office on May 16, 1927. The first office was located in Roselle, NJ in the home of fraternity's first executive director, Harold Jacobsen.

That same year, the fraternity saw the first publication of the Keryx newsletter. In 1937, Mississippi State University chapter was installed, becoming the first new chapter formed from a colony. Before the Alpha-Lambda chapter, all new chapters had been fraternities or societies already in existence that agreed to consolidate into Sigma Pi. That same year the fraternity hired brother James Hauser as its first field representative. By May 1940, Sigma Pi had 34 active chapters and 2 inactive chapters, and had begun using the new I Believe pledge manual. World War II decimated the fraternity, causing it to almost disappear entirely. As all able bodied young men left to fight for their country or to serve in defense plants, few college aged men remained. By the end of the war, Sigma Pi had
