Jacobi's early education was given by an uncle on his mother's side, and then, just before his twelfth birthday, Jacobi entered the Gymnasium in Potsdam.
Jacobi's maagang edukasyon ay ibinigay sa pamamagitan ng isang tiyuhin sa kanyang ina's side, at pagkatapos, lamang bago ang kanyang ikalabindalawa kaarawan, Jacobi ipinasok ang himnasyo sa Potsdam.
