Bartholdy, Jacob Levi Salomo, was uncle on the mother's side to Felix Mendelssohn born, in Berlin, 1779, died in Rome, 1826. He became a member of the Protestant Church in 1805, and through his influence the whole Mendelssohn family became Christians. He served as an officer in the Prussian army, and in 1815 he was appointed consul-general in Rome. He wrote treatises on modern Greek, a description of the Terolese war, and "Traits from the life of Cardinal Consalvi." The Berlin Museum possesses his collection of antiquities, comprising Etruscan vases, bronzes, ivories, majolicas, etc., which are now displayed in the National Gallery.
Basevi, George Joshua, architect, followed the example of his brother-in-law Isaac Disraeli, in leaving the synagogue in 1817. But it must be stated that no writer expressly asserts that either of the two were received into the Church by baptism. This is known, that Basevi while inspecting the bell-tower of Ely Cathedral fell and was killed instantly, and then received Christian burial in the chapel at the east end of the Cathedral.
Bassin, Eliezer, born about 1840 in the government of Moghilev, Russia. In 1869 he went to Constantinople, and then after experiencing God's wonderful dealings with him (so graphically described by Miss Stern in her book "Eliezer") he made a public confession of his faith in Christ. He was afterwards a student of the L.J.S. Training College at Palestine Place, and was sent out as a missionary to Jassy, Roumania, by the same Society. Later he laboured for some years in Edinburgh, under a Scotch Society. He was the author of a work entitled, "The Modern Hebrew and the Hebrew Christian," London, 1882, which contains an autobiography, relating his experience after deserting from the Russian army, and information about the Hasidim, especially the sect "Habad." Also "A Finger-post to the Way of Salvation," 1882. In 1881 he published a pamphlet entitled "Eintracht" (Harmony), in which he pleaded the cause of the Jews against the Anti-Semitic agitation in Germany.
Bechar, J., baptized at Constantinople in 1873, studied at St. Chrischona, Basel, and was appointed later as City Missionary in Neuchâtel.
Behrens, A. J., convert, student and missionary of L.J.S, was pioneer Missionary in Safed in the forties of the 18th century and at Jassy in 1850.
Behrens, Rev. A. D., son of the former, esteemed of the L.J.S., whom the writer learned to know and love in 1873 at Breslau, was appointed to the charge of the Mission at Vienna in 1875. A daughter married the convert Glück, a physician of high standing in Bucharest. Thus father and child have made known God's truth in their respective spheres.
Behrens, S. J., another Jewish convert, was for twenty years accountant and collector of the Operative Jewish Converts' Institution, an exemplary Christian, and well beloved by all who came in contact with him. His life made a salutary impression upon his rich brothers in Hamburg, who, although they yet remained members of the synagogue, granted his wife a liberal pension for life.
Bellson, Rev. R., born in the neighbourhood of Cassel, Germany, in 1805. L.J.S. missionary from 1831, successor of Pauli in Berlin, 1844. He was an excellent scholar and was much respected by the cultured Jews. In the very first year of his activity there, he had the privilege of leading twenty Jewish souls to the Saviour. One of his converts was the Rev. A. D. Hefter, another Kappelin. He wrote in "Dibre Emeth," "Blätter für Israel's Gegenwart und Zukunft."
Belmonte, E., banker in New York, connected with Rothschild, joined the Protestant Church, whilst a number of the same family joined the Roman Church at different times. (See "Jewish Encyclopædia.")
Belmonte, Hannah, a near relation of Da Costa, and later his wife, became a Christian in 1822.
