Elhannan's diligent study of Chemistry, his commitment to achieving his PhD in Organic Chemistry was the the moving force of his ambition. He is to be admired, and remembered for that significant achievement and 30 years of being a professor of organic chemistry at a university. His students learned and enjoyed learning from Dr. Keller.
I am so sorry and saddened by his death. Rest in peace my first ❤
