Aharon Katzir

Aharon Katzir, Aharon Katzir - Katchalsky or even Aharon Katchalsky (* 1914 in Lodz, † May 30, 1972 in Tel Aviv) was an Israeli physical chemist. He was a professor at the Weizmann Institute in Rehovot.

Katchalsky came to Palestine in 1925 and today's Israel. There he slept with the Hebrew surname Katzir. In 1948 he became head of the Department of Polymer Research at the Weizmann Institute, and in 1952 Professor of Physical Chemistry at the Hebrew University in Jerusalem.

He focused on the electrochemistry of biopolymers and thermodynamics of biological networks.

In 1961 he was awarded the Israel Prize. 1962 to 1968 he was president of the Israel Academy of Sciences.

It was founded in 1972 in an attack on the Japanese terrorists Ben Gurion Airport (then Lod Airport ) killed ( massacre at Lod airport).

A lunar crater is named after him and he's on an Israeli postage stamp. Even a scientific center at the Weizmann Institute, a grant from the Israeli Ministry of Defense and a series of lectures at the Hebrew University (organized by his son, the physicist Abraham Katzir, a professor in Tel Aviv) bears his name.

He is the brother of Ephraim Katzir.
