Jeff was born in Hunterdon County, NJ, to C. Richard and Dorothy Dangler Jacob, and had one sister, Barbara “Barra” Jacob-McDowell. Everyone in the family loved history; family vacations were spent camping in the US and Canada, traveling to forts, battlefields, and museums. After graduation from Hackettstown (NJ) High School in 1961, he enlisted in the Air Force but during Basic Training received an honorable medical discharge due to an accident. He was employed by several businesses, including as Acting Manager of the Small Appliance Department for K-Mart, but his passion was military history. For over 40 years, he was a collector and later broker of medals of honor and orders of merit. Entirely self-educated, he wrote many articles in American, European and British journals, also collaborating on several scholarly books. He was the author of Court Jewelers of the World (Cherry Hill: 1978), the product of 15 years of meticulous research, that’s still a landmark publication in the field. “My big brother was brilliant and witty,” Barra recalls. “I once asked him who won the battle of Gettysburg. Almost three hours later, he let me out of his room, after re-enacting the entire battle for me. I can tell you: TheUnion won.” Jeff was his mother’s devoted caregiver for the last three years of her life. In 2007, he moved to Wheeling, WV. Since then, he established and maintained two small libraries in his senior complex, one in each of its two buildings. Serviceswill be private, followed by cremation and interment in NJ. He’s survived by his sister Barra Jacob-McDowell (John McDowell) of Pittsburgh, several cousins, and friends locally and world-wide.
