Professor Yehoshua Kolodny was a leading scientist in the field of geochemistry and a recipient of the 2010 Israel Prize in Earth Sciences. Throughout his academic career, he served as Head of the Department of Geology, Director of the Institute of Earth Sciences, and Dean of the Faculty of Natural Sciences at The Hebrew University.

His research work encompassed a wide range of fields, including the development of innovative methods for using stable isotopes to study ancient geological environments. His research focused on the study of chert and phosphorite rocks, brines, and metamorphic processes. He made significant contributions to understanding the geology of Israel, particularly in studying the rock formations of Judea and Mount Scopus Groups, the Dead Sea, and the Sea of Galilee.

His scientific achievements received wide recognition: in 1971 he was awarded the Landau Prize, in 2004 he was granted honorary membership in the Geological Society of Israel, and in 2010 he was awarded the Israel Prize in Earth Sciences.

Even after his retirement in 2004, Professor Kolodny continued to mentor students and teach, dedicating his life to deepening the understanding of geological processes in Israel and worldwide.
