Traveller and collector E. St.
Vráz (1860-1932) spent a period of three years (1885-1888) on the Gold Coast where he collected zoological and botanical material, hunted animals and photographed. During the same period Friedrich Louis Ramseyer, a missionary from Basel, spent time on the Gold Coast and photographed there as well.
Comparison of both photographical collections (now in the Naprstek Museum and the Basel Mission) enabled the identification of several hitherto unknown persons and localites.
