Eliezer E. Goldschmidt (Born 1938, Jerusalem) is an emeritus professor of agriculture at the Hebrew University of Jerusalem. He is a Ph.D. since 1968, and a professor since 1982.


He is mostly known for his many research projects on the citron genetics,[1] shape variability of citrons,[2] and all which is relevant for the citron cultivation for etrog ritual. He developed an auxin which is very instrumental in preserving the style and stigma of the citron, which adds beauty and halachic promotion to an etrog.

He has many credits on different citrus species, and general agriculture as well.

He mastered a book named The Biology of Citrus together with Pinhas Spiegel-Roy,[3] and a lengtful article A History of Grafting together with some other scientists in the United States.[4]

He is one of the retirees from the Hebrew University faculty, working on a project to lengthen the shelf live of produce, and to heighten the produce of wheat.[5]
