Ludwig Ingwer Nommensen was a GermanLutheranmissionary to Sumatra who also translated the New Testament into the native Batak language. Stephen Neill, a historian of missions, considered Nommensen one of the greatest missionaries of all time. He is commemorated as a missionary on November 7 in the Calendar of Saints of the Lutheran Church with John Christian Frederick Heyer and Bartholomäus Ziegenbalg. Nommensen was born in the Nordstrand peninsula in 1834, when the area was part of Denmark. In 1846, a horse cart rolled over his legs, crushing them. The initial prognosis was that he would be unlikely to walk again. After praying for recovery, some three years later, he was able to walk again. An interest in Christian missionary work led to Nommensen's enrolment at the Rhenish Missionary Society seminary at Wuppertal-Barmen in 1857. He was sent as a missionary to Sumatra in 1862. He focused his attention on the Batak people of the interior of Sumatra. His first mission station was in the Silindung Valley. He experienced initial difficulties, but later succeeded in converting several local chiefs and their followers to Christianity. By 1865 he reported that 2000 Batak had converted to Christianity. At first most converts had to leave their villages, and came to live with Nommensen in his Huta dame. In 1878 he completed the first translation of the New Testament into the Batak language. In the same year he, his fellow missionaries and the Christian Batak were threatened by the Batak priest king :id:Sisingamangaraja XII|Singamangaraja XII who had gained support from Aceh that was involved in a war against the Dutch occupants. In the subsequent military expedition against Singamangaraja XII, which became known as the First Toba War, Nommensen played a prominent role in serving the colonial army as an interpreter and cultural consultant. Nommensen himself laid out his involvement in the war in a report that was published in BRMG 12, 1878:361–81, in which he explained that his involvement was aimed to save lives and to avoid Dutch brutal punitive action against local villages. After the war Nommensen was seen by Batak people as the one who could protect them against Dutch influence. In 1890 he moved north to the village of Sigumpar near :id:Laguboti|Laguboti. The area had greater Islamic influences, but Nommensen remained successful in building an indigenous Batak church. He had already instituted a church order and hierarchy, overseen by a Batak ephorus. By the time of his death the church numbered 180,000 members, with 34 Batak pastors and 788 teacher-preachers. Today most Toba Batak Christians belong to the Huria Kristen Batak Protestan church, one of the largest church denominations in Asia. He was awarded an honorary doctorate of theology by the University of Bonn, and in 1911 he was made an officer of the Dutch Order of Orange-Nassau. The Batak Christian University at Medan and Pematang Siantar was named Nommensen University in 1954. Bishop Stephen Neill, in his History of Christian Missions, describes Nommensen as “one of the most powerful missionaries of whom we have record anywhere”. Another source writes, “Nommensen may have been one of the most successful missionaries ever to preach the gospel”.
