Tom D. Neumann was a prominent national security expert and longtime advocate for strong U.S.-Israel relations. He co-founded the Jewish Institute for National Security of America (JINSA) in 1976 alongside Michael Ledeen and served as its Executive Director, later Executive Vice President, for nearly four decades until his retirement in 2014. In his leadership roles, he focused on policy, fundraising, and organizational direction, guiding JINSA to become an influential think tank promoting robust American defense policies and close security cooperation with Israel. Under his tenure, JINSA organized educational programs, policy briefings, and trips for U.S. military and civilian leaders to Israel.

Neumann's work emphasized countering shared threats such as terrorism and regional instability, and he frequently testified before Congress and contributed to media discussions on national security. His career extended beyond JINSA; he held positions in government and consulting, including roles in the U.S. Department of Defense and as a consultant on international affairs. Recognized within pro-Israel and defense communities for bridging military expertise with policy advocacy, Neumann was known for his strategic insight into Middle East dynamics and U.S. foreign policy.

Tom D. Neumann passed away on October 10, 2023, leaving a legacy in shaping bipartisan support for U.S. defense initiatives and Israel ties. His contributions continue to influence JINSA's mission.
