Jacob Levi Salomo
Salomo was the maternal uncle of Felix Mendelssohn. He was born in Berlin in 1779 and died in Rome in 1826. In 1805 he became a member of the protestant church and through his influence the whole Mendelssohn family became Christians.
Bartholdy served as an office in the army of Prussia, and was appointed consul-general in Rome in 1815. He wrote treatises on modern Greek, a description of the Terolese war, and “Traits from the life of Cardinal Consalvi”. He was also a collecter of antiquities.
It was all too common in the 1800s for assimilated Jews to pave their way into society and an acceptable profession by converting to Christianity. There is no way for us to know whether this was the case with Jacob Bartholdy and his relatives, the Mendelssohns. Only the personal testimony of each person can bear witness to whether they did or did not have a saving knowledge of Messiah.
