Rudolph Friedrich Hohenacker (1798 – 14 November 1874) was a Swiss missionary and botanist born in Zürich.
Shortly afterwards he relocated to Esslingen, Germany (1842-1858), and in 1858 moved to the town of Kirchheim unter Teck.
Following his return from the Transcaucasus, Hohenacker earned his living selling biological specimens of other collectors sorted in exsiccatae and exsiccata-like series.
[1] Hohenacker also contributed specimens to the German scientific society Unio Itineraria for plant exchange until 1842.
[2] He was the author of Enumeratio Plantarum quas in itinere per provinciam Talysch collegit.
