I am deeply saddened by this loss and extend my heartfelt condolences to the family. I was fortunate to have Dr. Lieber as a mentor and guide during my academic journey, taking several courses and seminars with him and having him as an advisor for two graduate degrees. With my office next to his, I had the privilege of engaging in a constant exchange of questions and ideas—from discussions on LIGO to Elba and Ebla. These collaborations, paired with conference trips and meetings that extended well into my career, were invaluable. His vast knowledge, insightful guidance, and unwavering inspiration made seemingly impossible goals achievable and difficult challenges surmountable. Equally significant were the warm visits to his home, where his family’s generosity and kindness provided critical support and encouragement throughout the years. Dr. Lieber always made time to be a visiting colloquium speaker and theory school presenter, captivating everyone with his engaging presence and unparalleled expertise. He was an extraordinary role model, and his loss leaves a profound void. He will always be deeply missed, but his legacy and impact will endure forever.
