and unwillingness to accept the Gobat's advice over the location of the mission. In 1839, he along with his new fellow missionaries Johann Ludwig, Krapf, and Carl Heinrich Blumhardt removed the mission station to Shoa, Ethiopia, where he spent for four months before leaving for London; later, he was responsible in mission expulsion from Ethiopia in 1843 forever—In 1842, when Isemberg returned to Shoa, his mission was refused entry forcing him to turn his attention to Tagray again. However, his expulsion in June 1843, effectively ended CMS activities in Ethiopia. Western India With no possibility of return to Ethiopia, he was transferred to the CMS mission in Bombay (present day Mumbai), Western India – Bombay Presidency. In Bombay, he devoted most of his missionary work to a settlement for freed African slaves, some of whom returned to Africa after being trained as evangelists. Having diagnosed as terminally ill, he left India to Germany in 1864; later, died at an age of fifty-eight on 10 October 1864 at Kornthal, near Stuttgart, Germany. Bibliography While in London, he published a number of small dictionaries in several Ethiopian languages like Afar(Danakil), Amharic, and Oromo language(Galla) in 1840, 1841, and 1842; however, Oromo language dictionary was based on German manuscript by Krapf. – These dictionaries were considered as the first dictionaries of these languages. In 1841, he published Dictionary of Amharic, and a comprehensive grammar in 1842. In addition to these, he also published several books to be used in [future] missionary schools, his mission tried to establish in Ethiopia—The texts which Isenberg wrote in Amharic plays a role in early Amharic literature. For evangelizing the natives, he translated Anglican Book of Common Prayer into Marathi and Amharic language in 1842, including his missionary efforts in revising Bible translations into local languages of respective missionary stations—Marathi and Amharic languages. In 1843, in association with his colleague Johann Ludwig Krapf, he published at London a memoir of his time in Ethiopia entitled Journals of Isenberg and Krapf, detailing their proceedings in the Kingdom of Shoa and journeys in other parts of Abyssinia in the years 1839, 1840, 1841, and 1842. This journal contains the information about the theological controversies that were raging in the Ethiopian church of those times, including the details about the people, politics, and its geography.
