Tobias Geffen (; August 1, 1870 – February 10, 1970) was a prominent American Orthodox rabbi who served as the spiritual leader of Congregation Shearith Israel in Atlanta, Georgia for six decades, from 1910 until his passing in 1970. He is widely recognized for his 1935 halachic ruling that officially certified Coca-Cola as kosher.
Biography
Geffen was born in Kaunas (then known as Kovno), Lithuania, and received his rabbinical ordination from Rabbis Tzvi Rabinowitz and Moshe Danishevsky at the Slobodka Yeshivah. In 1903, he emigrated to the United States and initially took up the rabbinate at Congregation Ahavat Zedek in New York City. Due to overcrowding issues, he relocated in 1907 to Canton, Ohio, where despite health challenges, he managed to unify the local Jewish community effectively. Following medical recommendations, Geffen moved to Atlanta in 1910 to assume leadership of Congregation Shearith Israel, a position he held until his death at age 99.
While in Atlanta, Geffen established the city's inaugural Hebrew school within his residence and initiated a daily Talmud study program. He consolidated kosher supervision across the region under his jurisdiction and served as head of the Southern division of the Union of Orthodox Rabbis.
An accomplished scholar, Geffen authored eight volumes focusing on Talmudic studies and biblical interpretation. He passed away on February 10, 1970. His grandson David drew inspiration from his life story to create "The Georgia Variations," an interactive Choose Your Own Adventure-style educational game employed by Gesher Educational Affiliates for teaching Jewish heritage.
Kosher certification of Coca-Cola
Residing near the headquarters of The Coca-Cola Company in Atlanta, Geffen was frequently consulted by rabbis nationwide regarding the kosher status of Coca-Cola, including its suitability for Passover. Upon reviewing the beverage's ingredient list and obtaining confidential access to its secret formula, he identified glycerin derived from non-kosher beef tallow as problematic. He successfully convinced the company to replace it with glycerin sourced from vegetables.
A further complication arose concerning Passover observance because grain-based ingredients are forbidden; trace amounts of grain-derived alcohol found in a sweetener rendered Coca-Cola non-compliant during the holiday. The company’s chemists responded by substituting this with a blend of cane and beet sugar that preserved the original taste.
After these modifications, Geffen issued a responsum in 1935 affirming that Coca-Cola fulfilled kosher requirements for consumption year-round. He emphasized that even those adhering to the most stringent Halachic standards could drink Coca-Cola throughout all seasons, including Passover.
