Sigma Phi

The Sigma Phi Society (ΣΦ) is the second Greek fraternal organization founded in the United States and the first to establish a chapter at another college, making it the first national Greek organization.

History
The Sigma Phi Society (ΣΦ) was founded on March 4, 1827, on the campus of Union College as a part of the Union Triad in Schenectady, New York. Its founders were: • Samuel W. Beall

• Thomas Fielder Bowie

• Rev. R. H. Chapman

• Hon. Charles T. Cromwell

• George N. Porter

• Hon. Charles N. Rowley. The Alpha chapter of Sigma Phi at Union College has been in continuous operation since its founding, making it the oldest continuously running fraternity chapter in the United States.

In 1831, Beta of New York was established at Hamilton College, making the society the first Greek fraternal organization in the United States to establish a chapter at another college. Thus, Sigma Phi Society is the first National Greek Organization in the United States.

The practices and rituals of the Sigma Phi Society are relatively unknown due to its establishment, and continued consideration, as a secret society.

Sigma Phi is a founding member of the North American Interfraternity Conference.

Symbols
The Sigma Phi badge is a monogram with a jeweled Σ directly over a Φ that is either plain or chased. It was designed by Charles N. Rowley, founder of the Beta of New York chapter. In 1879, Baird's stated that the badge was royal purple. Since 1879, the badge has been produced mainly in gold. Some gold plated options have been made available and in 2024 three options were introduced; sterling silver, with a gold plating on top, with pearls for $150 base price engraved, 10k gold for $675 plus engraving, and in gold filled for $375, engraved. All the options include pearls as gems have been out of fashion for sometime now.
