Heinrich Vieter was a German Pallottine missionary to the German colony of Kamerun. Vieter arrived in Douala with seven other members of the mission on 25 October 1890. Over the next 13 years, Vieter led the Pallottines as they opened missions and schools across the territory. He befriended the young Ntsama Atangana at the mission school in Kribi; Atangana would later gift the Pallottines with land in Jaunde. When a Bulu leader Martin-Paul Samba was sentenced to death for treason against Germany in 1914, Vieter appealed for a stay, but his requests were ignored.
