[1] In 1916, its members were interested in affiliating with an intercollegiate Greek-letter organization, specifically Acacia which was the only national Masonic fraternity at the time.

[1] Instead, the club adopted the name Square and Compass in 1916, forming a fraternity that could accept members of other Greek letter organizations.

[1] However, any expansion plans were put on hold on the eve of World War I when the fraternity's two leaders left immediately to enter the Reserve Officers' Training Corps on May 14, 1917.

[1] Although the Great Depression led to a decline in the fraternity's vitality, by the beginning of World War II, it had initiated nearly 4,500 members and had expanded to 57 chapters.

The Square and Compass badge was diamond-shaped with the letters M, F, C & E at the four corners and two secret characters in the center.

[6] Its pledge button was a circle divided by the letter S in navy blue and silver gray.

[8] Square and Compass adopted the Masonic model where interested candidates applied for membership, rather than opting for a typical Greek letter organization bidding process.

[1] Square and Compass was governed by national officers who met at biennial convention.
