A founder of the Hatzoloh Medical Rescue Squad in Manhattan, Shalom Lamm also served on the board of directors for Camp Morasha, The Jewish Institute for National Security Affairs (JINSA), and Yeshiva College. Following decades of work in the construction industry, Shalom Lamm founded Operation Benjamin.
Created to honor Jewish soldiers who gave their lives in World War II as part of the US military, Operation Benjamin takes its name from Private Benjamin Garadetsky. The project discovered that Garadetsky lay in a grave in the Normandy American Cemetery and Memorial under a Latin Cross, marking him a Christian, despite his Jewish roots.
Operation Benjamin helped facilitate the paperwork required for replacement of that gravestone with a Star of David. That ceremony took place in the summer of 2018.
Since then, Operation Benjamin has collaborated with the American Battle Monuments Commission (ABMC) to identify other Jews who also received grave markers not reflecting their true faith. Most recently, in February of 2020, the organization had the Star of David placed on the graves of five such soldiers located throughout the Manila American Cemetery in the Philippines.
