A visionary philanthropist and one of the Weizmann Institute’s longest-standing friends, Mr. David Lopatie of South Africa, has made a heartfelt gift to construct a lounge in the historic Sieff Building in memory of the victims of the Hamas onslaught of October 7, 2023.
“Following the trauma of the October 7 attack, I am more committed than ever to investing in sources of hope,” Mr. Lopatie says.
Inaugurated in 1934 as the Daniel Sieff Research Institute, this landmark building will soon undergo an extensive preservation and renovation project, reopening as a national heritage site and museum.
The second floor is home to Dr. Chaim Weizmann’s organic chemistry lab and personal office, which were damaged during the Iranian missile attack in June. These spaces, which had welcomed visitors for decades, will become the centerpiece of a permanent exhibit celebrating the remarkable legacy of Dr. Weizmann and the Weizmann Institute, and their fundamental contributions to advancing science and the State of Israel.
Once renovated, the Sieff Building will also serve as a vibrant gathering place for Weizmann scientists and their colleagues from Israel and abroad, hosting lectures, student thesis defenses, and other special events.
The new lounge, generously dedicated by David Lopatie, will provide an inviting space for Weizmann’s international community of students and scientists to brainstorm, exchange ideas, and plan collaborations. As he shares, “It will present a meeting venue between history and the future.”
The lounge will foster an inspiring atmosphere, offering an enriching experience and a vibrant environment for academic and personal growth. Renovations are expected to begin in January 2026.
