Löwenthal, Rev. Isidor, a native of Posen, where he received a liberal education, finishing his studies at the Gymnasium at the age of seventeen. His father wished him to enter into business, but he had no taste for such a life. With companions of the same age, he founded a liberal political union, and owing to a poem of a radical character, which he recited in public, he was arrested by the police. For this reason he emigrated to New York in 1846. On his arrival he tried to get employment, but failed. He was then obliged to become a pedlar. One cold November day he offered his goods to the Rev. S. M. Gayley, of Wilmington, Delaware, who, noticing his poor plight, invited him to his house, where in conversation he soon learned that Löwenthal was well educated. He then offered him hospitality until he should find a situation as teacher of German and French. This he procured for him in Fayette College at Easton, Pa., in 1847. There Löwenthal was indefatigable in his studies of the English language and literature. His iron will and his excellent memory enabled him soon to overcome all difficulties. Hitherto he had not revealed to Mr. Gayley his Jewish nationality, but now he not only did this but also told him that the family prayers and the services which he had attended had led him to study the Scriptures, and that he was convinced of the truth of Christianity. He was then baptized by Mr. Gayley in the Presbyterian Church. In 1848 he became teacher of languages at Mount Holly Collegiate School, where he remained several years. Mr. Philipps, of the First Presbyterian Church, New York, advised him to study for the ministry, and he entered the Theological Seminary at Princeton, New Jersey in 1852. During his course there he contributed articles to the "Biblical Repository." When about to leave the Seminary, he gave a lecture on Indian missions and then offered his services to the Board of Foreign Missions. The Board sent him in 1856 to Afghanistan. He acquired the language in one year, so that he could preach in it fluently; but he was only permitted to labour there seven years. During this short time he translated the whole of the New Testament in Pushtu and printed it, and compiled a dictionary of that language which he left in manuscript. He preached easily in five languages, and none knew the East better than he did. He possessed the largest collection of Asiatic MSS. and rare books that ever was the lot of a European. He was beloved by the natives and Europeans alike. Sir John Lawrence, especially during the mutiny, consulted him as a friend. He preached uninterruptedly in Afghanistan and in the Khyber Pass. At the last, he was shot dead by his own servant, it is said through a mistake, who, seeing him walking on the roof at night, took him for a thief. This was in 1864, when he was only thirty-eight.
Lowitz, Rev. J., laboured for years as a missionary of the British Society at Algiers, where he also acted as agent for the British and Foreign Bible Society. In 1872 he succeeded Davidsohn as principal of the British Society's Home for Converts and Enquirers, at 28, Alfred Place, Bedford Square, London.
Lucky, Rev. C. Theophilus, a native of Tisminitz, in Galicia, and a most remarkable convert to Christianity in the nineteenth century. He was known not only as a great Hebrew scholar, writing Hebrew in classical style as a living language, and as thoroughly conversant with the whole range of Jewish literature, but also as possessing a wide knowledge of Christian literature. Having studied at the Berlin University and High School for the knowledge of Judaism, and making researches in philosophical and religious subjects, he was led to become a believer. Lucky received Evangelical ordination in New York. In 1887 he first published a Hebrew periodical, "Eduth le Israel," which he continued for some years, when he returned to Galicia and took up his residence in Stanislau. There he lived and laboured among his brethren, preaching by the written and spoken word, but above all by his example, scarcely receiving any help from men. He was a living illustration of a Hebrew Christian of the first century; though thoroughly Orthodox as to the cardinal doctrines of Christianity, yet he believed that it was incumbent upon him to observe the Jewish Sabbath and all other Jewish festivals and the dietary laws, not for the sake of being justified by the works of the law, but for the sake of satisfying his own conscience, and that he might be more useful as an evangelist amongst his brethren in Galicia.
Maas, Dr. M., was a teacher at Breslau in the nineteenth century, and wrote the following works, advocating amalgamation of the Jews with Christians: "Die Sociale Stellung der Juden in Deutschland und das Ceremonial Gesetz," Löbau, 1876; "Die Mischehe das Einzig wirksame mittel einer dauernden Vereinigung zwischen der jüdischen und christlichen Bevölkerung Deutschland's," ib.
Mackhan, Beatus Christian (Nehemiah Cohen), after having travelled in three continents, and held the office of Rabbi at Avignon embraced Christianity, in the Baltic Provinces in 1672. In 1690 he published in the German language: "Schriftmässiger Jesus—Palmbaum oder Klarer Beweissthum wider die Juden, dass Jesus der wahre Messias sei" (Riga), Wolf, Bibliotheca Hebraica 3. N., 1648.
Magath, Rev. Julius, some time after his baptism became Professor in the Wesleyan College in Oxford (Georgia, U.S.A.) Later on he was requested by the Conference to do missionary work among the Jews. In 1886 he published a periodical entitled, "The Hebrew Missionary," and this was changed in 1888 to "The Hebrew Messenger." He also translated a treatise, written by the Roman Catholic Jewish convert M. M. Leman, entitled, "Jesus before the Sanhedrin," 1887.
Maimuny, Rabbi Mordecai, was born at Bona, Algeria, in 1817. His father was a well-to-do goldsmith, who had settled in Tunis in 1823, where Maimuny received a strict rabbinical education. When Dr. Ewald was stationed at Tunis, Maimuny was his great opponent and used to blaspheme the name of Jesus. Later on he went to Jerusalem, where his fanaticism became more excited when he observed the activity of Bishop Alexander. However, the bishop's calm and gentle disposition made a great impression upon him, and he received a Hebrew New Testament, which he studied diligently and became a changed man. His wife seeing that he visited Nicolayson and the other missionaries was very angry with him. To pacify her, and in the hope that she would change her mind, he left Jerusalem with her, and they wandered through Asia, North Africa, and Europe, and then returned to Jerusalem, where he had to undergo great persecution, and was obliged to return to his native place. Finally, in 1853, he was baptized by the Scotch missionary, the Rev. Benjamin Weiss.
Mamlock, L. C, a native of Kalisch, was instructed and baptized by Dr. Ewald in 1863. After being in the Operative Jewish Converts' Institution for some considerable time, Dr. Ewald employed him as his assistant, and he became a parochial lay reader. Subsequently he was appointed by the L.J.S. as missionary in Manchester, and was transferred to Paris after the Franco-German war. There he laboured faithfully the rest of his life, spreading the Gospel far and wide during several exhibitions, and had the privilege to see many sons and daughters trusting in the Lord Jesus Christ for their salvation.
Marcus, Moses, born in London, 1701, was sent by his father to Hamburg for his education. There he had intercourse with Christians, read the New Testament, and came to a saving knowledge of the truth. In 1721 his father returned to England from India, where he had amassed a fortune, and summoned him to come home. Marcus then told his father of his religious convictions, when the latter was shocked, and threatened to disinherit him if he should be baptized; he once even threw a long knife at him. Marcus, however, persevered and was baptized in 1723. In 1724 he wrote a pamphlet entitled, "Principal Motives to leave the Jewish Faith." In defence of Christianity, against the then prevalent rationalism, he translated into English the second part of Dr. J. Gottlob Carpzov's "Critica Sacra," adding his own notes (London, 1729).
Marcusohn, Rev. J. W., was sent by the Scotch Church as a missionary to Constantinople, at the request of the American Board of Missions, in 1859. He subsequently preached the Gospel to the Jews in the United States of America.
