[1] Nevermann spent much of his working life in Costa Rica, where he was a resident from about 1909.
[2] He owned a banana plantation called the Hamburg Farm near the Reventazón River at Ebene, Limón[3] (near the modern town of Cairo[4]), and was a professor at the National School of Agriculture.
[7] In June 1938 Nevermann invited his friend, the entomologist Alexander Bierig (1884-1963), to stay with him on his plantation.
On the night of 30 June, while out collecting insects, Nevermann and Bierig were accidentally shot by an American hunter[8] passing through the area, who had mistaken them for an animal.
[5] in 1941 Nevermann's collection of Costa Rican Coleoptera was accessioned by the U.S. National Museum.
