Ambassador John Langeloth Loeb, Jr., one of the American Jewish Historical Society’s most prolific donors, both in terms of collections and philanthropic support, passed away on August 5, 2026. It is with a heavy heart that I write this, as one of the AJHS archivists who processed the Loeb Family Papers and had the good fortune of meeting him several times.

Ambassador John Langeloth Loeb, Jr. born May 2, 1930, was the eldest of five children of John Langeloth Loeb, Sr., and Frances (“Peter”) Lehman Loeb. His siblings included twins Arthur Lehman Loeb and Ann Loeb Bronfman, and sisters Judith Loeb Chiara and Deborah Loeb Brice. John, Sr., was the son of Carl Loeb, a metal magnate and founder of the investment bank, Loeb, Rhodes, and Co., and Adeline Moses, who traced her ancestry to the American Revolution and helped fund the Central Park Boathouse. “Peter” was the daughter of the eldest Lehman son, Arthur, whose brothers were New York Governor Herbert Lehman and Chief Judge of the New York Court of Appeals, Irving Lehman. Arthur’s wife was Adele Lewisohn Lehman, daughter of Adolph Lewisohn, one of the wealthiest American men of the late 19th and early 20th centuries.
Arthur, Herbert, and Irving’s parents were Mayer and Babette Neugass Lehman. Mayer was one of three original Lehman Brothers who immigrated from Germany to Montgomery, Alabama. They eventually moved their linens business to New York City, and Lehman Brothers began as a commodities and investment bank. Arthur headed Lehman Brothers until his untimely death in 1936 at the age of sixty-two.
As the eldest son, John, Jr. followed his father into banking but eventually decided to move away from the family business and into politics and philanthropy. Under President Ronald Reagan, he was appointed ambassador to Denmark between 1981-1983, which ultimately led him to a career in government after his term ended. His storied career included roles as a delegate to the United Nations and as an environmental advisor to New York State Governor Rockefeller. He further worked on environmental issues with the New York State Council of Environmental Advisors and served as Chair of the Keep New York State Clean Program.
Ambassador Loeb’s philanthropy reached beyond environmental issues. He funded projects at the Touro Synagogue in Rhode Island, and established the George Washington Institute for Religious Freedom (GWIRF), as well as the often-used John Langeloth Loeb, Jr., Database of Early American Jewish Colonial Portraits. He also produced several books on his family, expanding on their genealogy and legacy.
In 2015, the AJHS bestowed our Emma Lazarus Statue of Liberty Award to Ambassador Loeb for his lifelong philanthropic work and dedication to the cause of historical preservation.
This is a short list of Ambassador Loeb’s accomplishments and endeavors. He dearly loved the legacy that was his family, and he gave that legacy to the American Jewish Historical Society to preserve, and for that, we are deeply honored.
Ambassador Loeb leaves behind his wife, Sharon Handler, children Alexandra Loeb Driscoll and Nicholas Mears Loeb, and brother Arthur Lehman Loeb, and sister, Deborah Loeb Brice.
May his memory be a blessing.
