Biography

Geffen was born on August 1, 1870, in the Lithuanian city of Kaunas. He immigrated to the United States in 1903 and became rabbi of New York's Congregation Ahavat Zedek in New York City. In 1907, he moved to Canton, Ohio, to become the rabbi of a small synagogue. In 1910 he moved to Atlanta, Georgia, where he served as rabbi of Congregation Shearith Israel until his death.
Geffen organized the first Hebrew school in Atlanta. He began a daily class in Talmud. Geffen also standardized regulation of kosher supervision in the Atlanta area under his central authority. He was the leader of the Southern division of the Union of Orthodox Rabbis.
Geffen published eight books of Talmudic and Biblical exegesis. He died on February 10, 1970.

Kosher certification of Coca-Cola

Since he lived in Atlanta near The Coca-Cola Company's headquarters, Geffen received many inquiries from rabbis across the United States inquiring whether Coca-Cola was kosher and whether it was kosher for Passover. He asked the company for a list of the beverage's ingredients. Geffen was provided with the Coca-Cola formula, a closely guarded trade secret, on the condition that he not disclose the formula.
Geffen discovered that one ingredient was glycerin produced from tallow from non-kosher beef. He convinced the company to substitute a vegetable-based glycerin.
A similar problem presented itself concerning the use of Coca-Cola during Passover, when Jews are not permitted to consume products derived from grains. One of the sweeteners used in Coca-Cola included traces of alcohol produced from grain, rendering the drink impermissible during Passover. The company's chemists found that a sweetener made from cane sugar and beet sugar could be used without changing the beverage's flavor.
Satisfied that Coca-Cola's ingredients were kosher, Geffen issued a responsum in 1935 that Coca-Cola was kosher for year-round consumption. "With the help of God, I have been able to uncover a pragmatic solution according to which there would be no question nor any doubt concerning the ingredients of Coca Cola", he wrote. "It is now possible for the most stringent Halachist to enjoy Coca Cola throughout the year and on Passover."
