George Theodosios Frantzis (January 13, 1911 – May 30, 1970) was a Greek-American lawyer, school principal, community leader and supporter of the sponge industry in Tarpon Springs, Florida.
In January 1943, Frantzis helped Tarpon Springs obtain a 70-ton marble altar from Mount Pentele, in Athens, Greece, that was part of Greece's entry into the 1939 New York World's Fair, held in Queens, New York.
[2] Frantzis also organized the Committee for Reorganization of the Sponge Industry in 1955, serving as the group's first president.
[3] Frantzis wrote Strangers at Ithaca: The Story of the Spongers of Tarpon Springs (St. Petersburg, FL: Great Outdoors Association, 1962; OCLC 1687861), an account of the sponge divers and development of the Greek community in Tarpon Springs.
The Great Floridian plaque for him is located at the site of his retail building at 715 Dodecanese Boulevard.
