Prof. Yaakov Krakower


Prof. Yaakov Krakower joined the faculty of Bar-Ilan University in 1969. He was born in Brooklyn, New York and attained his B.S. from Yeshiva University. He received his rabbinical ordination from Rabbi J.B. Soloveitchik. In 1954, he completed his M.S. Degree at Columbia University and then went to Wayne State University in Detroit, Michigan to carry out his doctoral dissertation under the noted authority on fertility, Prof. Carl Djerassi. Subsequently, Prof. Krakower was employed for 10 years by Squibb Pharmaceuticals in the field of endocrinology and fertility. 

In 1969, Prof. Krakower and his family came on Aliya where he joined the Chemistry Department at Bar-Ilan University.

Prof. Krakower exemplified “Torah with Derech Eretz” and for decades, he conducted a weekly Talmud shiur for the faculty in the department.

His area of scientific research focused on natural products, in particular, steroids and the spectroscopy of organic natural materials. Prof. Krakower also served as Halachic and scientific advisor for Badatz Mehadrin-HaRav Rubin in Rehovot.

Prof. Krakower was an outstanding lecturer and a devoted mentor. He was much beloved by his students whom he guided with care and consideration. He was an excellent administrator and served as Chairman of the Chemistry Department for two terms. His colleagues and students considered him to be “a real mensch”.

Prof. Krakower is survived by his wife, Risha, their six children and many generations of loving descendants.



Dr. Moshe Ben-TzionDr. Moshe Ben-Tzion


It is with great sadness that the Chemistry Department of Bar Ilan University announces the passing of Dr. Moshe (Mel) Ben-Tzion, one of the pillars of the department. Dr. Ben-Tzion was a devoted and beloved lecturer for many years and was Deputy Head of the department from 1988 until his retirement in 2013. 

Moshe Ben-Tzion is remembered not only as a remarkable and inspirational tutor and teacher; but also, for his many contributions to the department’s teaching and administrative activities.

Moshe was highly influential in the development and growth of academic teaching in the Chemistry Department. His impact on the curriculum development programs and projects of the department cannot be overstated. For example, he was one of the key proponents behind the introduction of computational courses in the Chemistry curriculum and was deeply involved in the establishment of the student computer laboratories in the department.

Prof. Yehoshua SchachterProf. Yehoshua Schachter


Prof. Yehoshua Schachter joined Bar-Ilan in 1960, as the chairman of the department of chemistry. He served in the position for 5 years, followed by one year as the Rector of the University.

Prof. Schachter graduated from the Technion of Viena in chemical engineering with excellence (in spite of his anti-Semitic professor) in the mid-thirties, where he established the Zionist student organization (Blau Weiss). In 1935 he left for Milano, warning all his friends to leave as well. In 1940 the British granted Schachter a certificate to enter Palestine, to head a top secret project at the lab of Prof. Farkash at the Hebrew University. The project involved calcification of bromide from the Dead Sea for shipping to England to serve as a crucial additive for airplane fuel. Later on Schachter received his PhD in chemistry from the Hebrew University. During the War of Independence, Schachter produced gunpowder for the Hagana in Yerushlaim from raw material from the Dead Sea.

Following a period of research in Zahal as an Air-Force officer, and a couple of years in the Scientific Council, Schachter was appointed the head of research of Machzevei-Israel. Based on his patent for producing Ethylene Di Bromide, Machzevei-Israel built a plant in the Dead Sea.

Prof. Schachter research's in Bar-Ilan University was in the field of physical chemistry. He researched the use of oil shale as a source of energy.

Prof. Schechter was on the editorial of the Hebrew Encyclopedia, a member of the committee for selecting Israel Prize winners, one of the selected group to whom Prime Minister Ben-Gurion turned concerning the issue of "who is a Jew", and a member of the Committee of Higher Education.



Prof. Harry Friedmann

Prof. Harry Friedmann


Harry Friedmann (28 November 1931 - 28 May 2018) was a Professor of Chemistry who specialized in theoretical Nonlinear optics and lasers in Biology. He was born in Frankfurt am Main. Soon after his birth, the family fled to Czechoslovakia and from there to Belgium. He studied at the Université Libre de Bruxelles from 1951, gaining a Ph.D. with distinction in 1964 under the supervision of Nobel Laureate Prof. Ilya Prigogine. He was a Research Associate at the Weizmann Institute of Science (1962-1967), a Senior Lecturer at the Technion – Israel Institute of Technology (1967-1969) and then a Professor at Bar-Ilan University in the Chemistry Department. He became a Professor Emeritus at Bar-Ilan University in 1999. His research focused on quantum statistical mechanics, spectroscopy of molecules in rare-gas crystals, theoretical nonlinear optics, especially isotope separation, nonlinear optical processes in atomic systems, light propagation and storage, and also the effect of laser light on biological systems. He published over 120 papers in peer-reviewed journals, many of them were co-authored by colleagues Arlene Wilson-Gordon and Rachel Lubart.

פרופ' ברוורמן ז"לProf. Shmuel Braverman

 1934 – 2023

Prof. Shmuel (Samuel) Braverman joined the Chemistry Department at Bar-Ilan University in 1963 and became a Full Professor in 1990. He was born on May 23, 1934, in Falticeni, Romania, and immigrated to Israel on March 14, 1952. After his military service (1953-1956), he attained his BSc (1960, cum laude) at the newly established Chemistry Department at Bar-Ilan University and his PhD (1963) from the University of Alberta at Edmonton, Canada. He served as the Chemistry Department Chair (1968-70) and was a Visiting Professor at Cornell University (1976-1977), University of Illinois at Urbana (1980-1981), University of Alberta (1984), University of Toronto (1988, 1989, 1990, 1991), University of Lund, Sweden (1989), York University, North York, Ontario (1989), and University of Nijmegen, The Netherlands (1990). 

Prof. Braverman was interested in reaction mechanisms and organic synthesis. He focused on [2,3]-sigmatropic rearrangements of various allylic and propargylic sulfur esters. He discovered and studied the [2,3]-sigmatropic rearrangement of allylic sulfenates to sulfoxides (the Mislow-Braverman-Evans Rearrangement), propargylic sulfenates to allenic sulfoxides, and of allylic and propargylic sulfinates to the corresponding sulfones. In addition, he studied diradical cyclization and cycloaromatization of bridged diallenic systems (Garratt-Braverman Cyclization), electrophilic cyclization of monoallenic systems, tandem pericyclic reactions, enediyne models, heterocumulenes, especially sulfines, addition of chalcogen halides to propargylic alcohols, and regio- and enantioselective bromination and development of new processes of industrial interest. 

Prof. Braverman was a modest but determined scientist with enormous enthusiasm for teaching and research in organic chemistry which he pursued well into his eighties. Many generations of Bar-Ilan chemistry students benefitted from his excellent courses in basic and advanced organic chemistry. He is fondly remembered by the numerous graduate students and postdocs that he mentored. Prof. Braverman is survived by his wife, Batia, daughter Ayala, and grandchildren, Mattan and Noa.
