Graham Wilmot Brooke (1865-1892) was educated at Haileybury College and studied medicine at St Thomas's Hospital. He was initially engaged in independent missionary work in Africa but returned to England in 1889. He was then accepted as an Honorary Lay Missionary of the CMS to be joint leader with Rev J. A. Robinson of the new Sudan and Upper Niger Mission. In 1890 he went to Africa and served principally at Lokoja. He was engaged there in translating some tracts in Haussa but died of fever in Lokoja in March 1892.
