Apart from his evangelism, Ramseyer was instrumental in the expansion of opportunities in the fields of education, artisan industry training, land acquisition for building design and manpower development in the areas he lived and worked in.

[12] At the age of eighteen, he studied German at a college where he became interested in missionary work and was involved in a Christian Youth Group, before completing his mandatory military service.

[15] Schrenk, a believer in Pietist faith healing, was the General Treasurer of the Basel Mission Trading Company in Christiansborg and later experimented with cocoa planting in the early 1870s in Ghana.

[15] Gravely ill in 1858, Schrenk had visited faith healers in Germany, Johann Blumhardt at Bad Boll and subsequently Dorothea Trudel at Mannedorf between 1858 and March 1859, where he was fully healed.

Firstly, they sought to build up a focal station in Kyebi, the capital of the humid and densely-forested Akyem area – a region with a non-conducive climate to European missionaries.

After his sudden death, Christians were banished from the town and the chiefdom seized the mission station and chapel using them as the new king's official residence and durbar hall respectively.

[6] Amid various skirmishes, colonial soldiers stormed the town and restored law and order, leading to the eventual flourishing of the mission at the beginning of the twentieth century.

[6] The insights into the terrain were gleaned by Fritz and Rosa Ramseyer during their capture in 1869 by the Asante army during their forced march from Anum, located on the Volta River’s eastern bank to Kumasi, via the Kwahu State where the mountain range is situated.

[6][8] On 12 June 1869, Fritz and Rosa Ramseyer, together with their nine-month old son, Fritzchen, were captured by the Asante troops led by the army captain, Aduboffour while on their first official assignment in Anum.

[7][6][8] After several weeks of walking, the captives arrived on the outskirts of Kumasi in a small hamlet called Abankoro, where they were joined by the French merchant, Marie-Joseph Bonnat who had been captured in Ho, a few miles from the Ghana-Togo frontier.

Ramseyer rejected this option since in his view, paying a ransom in exchange for their freedom “would only reinforce the immoral habit of abducting people for ransom.” [7][6][8] The negotiations stalled for almost half-a-decade.

[7][6][8] In the royal household at the Manhyia Palace, the missionaries found a diplomatic ally in Owusu Ansa, a Western-educated prince whose father, Osei Bonsu (1801–1824) had been the Asantehene.

[8] In 1871, David Asante, the first native Akan missionary of the Basel Mission was sent on a fact-finding expedition in Begoro, north of Kyebi, one of the divisions of the Akyem Abuakwa State to gather details about Ramseyer and Kühne.

[8][7] The missionaries were finally considered for release in January 1874, when it became clear the Asante army had lost a key battle against the British, more commonly known as the Sargrenti War (1873–74) led by Sir Garnet Wolseley, an Anglo-Irish field marshal.

Marie-Joseph Bonnat’s magnum opus, a record of his years in captivity was found in 1979 in an attic in his old family lodge in his hometown, Grièges in the French department of Ain.

[6] The content of the manuscript validated the Ramseyers’ accounts of their captivity, even though the narrative was written from two perspectives, that of a Swiss Protestant missionary and a Catholic French trader/prospector, united by a strong belief in Christian teaching.

[7][6][8] The Ramseyers were temporarily settled at the Kubasehene Yaw Preko's house and fetish shrine under the auspices of the paramount chieftain of Abetifi, Nana Kofi Denkyi.

[8] He sometimes held open-air vigils and religious revivals where many natives, including fetish priests, Agya Yaw Tawi and Otuo Kofi converted to Christianity.

[8] This move was opposed by the local shamans who viewed Ramseyer as a threat to their livelihoods as many indigenes were abandoning the traditional religion in favour of the Christian faith.

[8] Rainstorm nearly damaged the building during construction, requiring reinforcement with wooden beams on the upper level using the architectural engineering, commonly found in Switzerland and Germany, distinct for English-style Tudor houses.

[7][6][8] They received a warm reception from the Asantehene who treated him as an old long-lost friend and presented to the king a Twi language Bible that had been translated by Johann Gottlieb Christaller, the German philologist and Basel missionary.

The Asante stool represented by the Asantehene, Otumfuo Agyemang Prempeh I, owed the British crown five thousand ounces of gold, as part of the treaty of Fomena, after it lost one of the Anglo-Asante wars.

The land is open for us to work!”[7][8] In June 1896, Rosa and Fritz Ramseyer, together with their nephew, Edmond Perregaux and Joseph Adjaye, a local Christian convert completed their move to Kumasi.

His wife, Rosa Ramseyer played a pivotal role in the girls’ education programme in Asante, teaching domestic science such as sewing, baking and household chores.

[8] According to scholars, domestic slaves who had been freed by the British administration in 1896 and were enrolled in Ramseyer's school were most likely re-taken into slavery by the Asante army after the Yaa Asantewaa War.

[22][23][6] The chapel was christened “Ebenezer” a reference to the Biblical verse in 1 Samuel 7:12, “how far the Lord has helped us”- an allusion to the pain, suffering and tribulations the Ramseyers had endured in Asante.

[8] In his final tour of duty, Fritz Ramseyer lived in Kumasi from 1906 until 1908,[24] before permanently returning to his home country, Switzerland, after forty-four years residing on the Gold Coast.

Many of his converts left their long-grass thatch roof, bamboo poles and beam huts and moved into the newly designed stone storey houses at the mission station in Adum.

[12] As a result of her ordeal in captivity, Rosa Ramseyer became partially paralysed and her health condition deteriorated over time, permanently leaving the Gold Coast in 1904.

[27] Other Presbyterian churches named after him include those at Bubiashie, North Kaneshie, Kwaso, Dansoman, Bompata, Wiaso, Kwahu-Tafo, Kwahu-Bokruwa, Nkwatia Kwahu, Abetifi-Kwahu, Hansua-Techiman and in Columbus, Ohio.
