Phi Delta Epsilon (ΦΔΕ) (commonly known as PhiDE) is a co-ed international medical fraternity and a member of the Professional Fraternity Association.[1]


Phi Delta Epsilon was founded on October 13, 1904 at Cornell University Medical College by Aaron Brown, Henry Aaronson, Michael Halpern Barsky, Bernard Hyle Eliasberg, Irving Harold Engel, Philip Frank, Abraham Leon Garbat, and William Isidore Wallach. During the first decade of this century there were many doors closed to Jewish medical students and physicians, doors which would not fully open until after World War II. In 1904, it was not uncommon for American medical schools to have quotas limiting admission of Jewish students, and medical fraternities. So Aaron Brown and his friends decided they would start their own fraternal organization, guided by the precepts of philanthropy, deity, and equity.

The success of the Cornell chapter soon led to the organization of other chapters in the East and Midwest. In 1918, Phi Delta Epsilon amalgamated with Alpha Phi Sigma, a medical fraternity organized in 1908, whose ideals and principles were similar to those of PhiDE. Its chapters were in the Midwest and West, making for an ideal union.

Following the amalgamation, the United States was divided into districts and, by 1930, enough members had graduated from medical schools allowing for the formation of graduate clubs. In 1926, an Endowment Fund was started giving the Fraternity long-term stability. In the 1940s the Aaron Brown Lectureship Program was begun and has remained a vital chapter event through the years.

In the late 1960s, the Fraternity opened its membership to women and encouraged recruitment of medical students of all races, nationalities and religious beliefs. The past 25 years have seen the Fraternity's membership become diverse, reflecting the diversity of the medical profession today. The addition of the premedical affiliation in 1994 at Binghamton University rounded out the Fraternity's membership, which now spans an entire lifetime of medical education and practice.

Symbols and Seal

Over the course of its history, the Fraternity has claimed three badges. The first and oldest badge includes the Greek letter Phi on its left side, Delta at its top, and Epsilon on its right. The Delta is set with pearls on its sides and amethysts at its angles. Below the Delta is a torch, and in front of the torch is a bow with a ruby at its center. All badges are identical, but as occasion demands various stones are placed therein to designate successful completion of a term in a specific International Board office.

The Fraternity's premedical badge is made of 14 carat gold and is triangular in shape. The left side of its face is purple, while the right side is ivory. The medical badge, also made of 14 carat gold, consists of a torch centered in front of the outline of a triangle.

The seal of the Fraternity consists of the scales of justice with the letters Phi, Delta, and Epsilon on the sides and at the bottom. The scale is balanced upon a caduceus with a Delta as its base. The letter Alpha appears beside the left wing and the letter Sigma beside the right. Above the center of the wings is a star containing the letter Phi.

Both badge and seal may only be used or worn by initiated members.

Other symbols of PhiDE include amethyst, pearl, and the scarlet red carnation.
