David Max Eichhorn (January 6, 1906 – July 16, 1986) was an American rabbi of Reform Judaism, a director for Hillel, a chaplain in the Army, an author, and an authority within Reform Judaism on the subjects of interfaith marriage and religious conversion.

In July 1942, Eichhorn was stationed at Camp Croft in Spartanburg County, SC and evidently assisted the local Jewish congregation, which was then without a rabbi.

[1] Throughout World War II, Eichhorn was assigned to serve in combat units in France and Germany, and was among the troops that liberated Dachau.

After returning from the war in 1945, Eichhorn retained his active military status in the United States Army Reserve.

Eichhorn died on July 16, 1986, of a heart attack at Holmes Regional Medical Center in Melbourne, Florida.
