Prof. Alfred Hassner
1930-2024
Professor Alfred Hassner was born in 1930 in Czernowitz, Romania (now part of Ukraine). His education was disrupted by World War II, but despite only completing the third grade before the war, he displayed remarkable resilience and determination. Surviving the Holocaust, he embarked on an academic journey that would leave an indelible mark on the field of chemical sciences.
Skipping grades 4 through 12, Hassner enrolled directly at the Technische Hochschule in Vienna (1949-1951) before moving to the University of Nebraska, where he completed his BSc in 1952. Under the guidance of Norman Cromwell, he continued his graduate studies at Nebraska, obtaining his PhD in 1956. Furthering his academic pursuits, he pursued post-doctoral training under Louis Fieser at Harvard from 1956 to 1957. Hassner's academic career flourished, beginning in 1957 at the University of Colorado in Boulder where he was appointed Full Professor in 1966, a position he held until 1975 when he transitioned to the State University of New York at Binghamton, where he was honored with the title of Distinguished Professor. In 1983, he relocated to Bar-Ilan University in Ramat-Gan, Israel, where he established a vibrant research group and remained actively involved in teaching well into his nineties.
Prof. 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.
