About Axel Elof Jäderholm (source: English and Swedish wikipedia) and the recipient Eberhard Stechow (source: wikipedia):
Axel Elof Jaederholm (born July 24, 1868 in Söderhamn–deceased March 5, 1927 in Norrköping) was a Swedish zoologist and botanist.
Biography: In 1888, Axel Elof Jäderholm entered the Uppsala University where he earned his undergraduate degree in 1892, and his doctorate in 1898. His doctoral research was about the South American Peperomia. Between 1903 and 1905, he worked on hydroid collections at the Swedish Museum of Natural History in Stockholm and the Imperial St Petersburg Academy of Sciences. Axel Elof Jäderholm established two new genera and 69 new species of hydroids, most of which are still valid today. Five species of hydroids have been named in his honor. The standard author abbreviation Jaderh. is used to indicate this person as the author when citing a botanical name.
Species established by Jäderholm:
Eudendrium caricum (1908)
Candelabrum austrogeorgiae (1904)
Candelabrum austro-georgiae (1905)
Distinctions: Knight of the Order of the Polar Star
Axel Elof Jaederholm, född July 24, 1868 in Söderhamn, död 5 Mars 1927, var en svensk zoolog och läroverklektor.
Jäderholm was a philosophy candidate at Uppsala University in 1892, philosophy license and philosophy doctor in 1898, adjunct in Örebro in 1905, lecturer in biology and science in Västervik in 1905 and lecturer in Samma Ämnen in Norrköping in 1913. Han företog flera forskningsresor till ett flertal europeiska countries including Jamaica and utgav många zoologiska work, publicerade i bland annat Vetenskapsakademiens Handlingar, treat företrädesvis kavitetsdjur (Coelenterata).

Eberhard Stechow (* 21. March 1883 in Berlin; † 11. August 1959 in Planegg) was a German zoologist and specialist in the group of Hydrozoa, especially their now obsolete order Hydroidea. This most closely corresponds to the subclass Hydroidolina used today.
Life: Stechow grew up in Zitzschewig, today a district of the Saxon city of Radebeul, in the Hohenhaus mansion, which his father Walther Stechow had acquired in 1885. He received his doctorate in 1908 under Richard von Hertwig in Munich with the dissertation “Contributions to the knowledge of Branchiocerianthus imperator Alm.” (a Japanese hydrozoan). To gain knowledge of this previously largely unexplored order, Stechow published over 40 scientific papers and described numerous new genera and species. He also created the first comprehensive identification tables of this order and placed particular emphasis on the phylogenetic relationships of the species within this taxon.
From 1905 to 1923, Stechow's place of work was the Munich State Zoological Collection, where he worked as a volunteer research assistant. He was employed at the same place as an assistant until 1927, from then on as a curator and from 1937 as a department head. After the death of his father, Surgeon General Dr. Walter Stechow, in 1927 Eberhard Stechow inherited the Hohenhaus in Radebeul.
His own research trips took him to the Mediterranean countries, the West Indies and California. From the zoological material he brought with him, Stechow built up a collection of hydrozoans in Munich, which he supplemented through exchanges with other specialist colleagues. Today, this collection houses over 1,000 objects preserved in ethanol as well as several thousand microspecimens, including numerous types and paratypes.
In addition to hydrozoan studies, Stechow's main area of work, he dealt with the oldest cultural history. He was the editor of a three-part “Natural and Cultural History of Lithuania”. In the last decade of his life he was primarily involved in research in historical geography.
In recognition of his scientific achievements, Eberhard Stechow became a member of the Leopoldina - the German Academy of Natural Scientists in Halle a. S. – and the Academy of Non-Profit Sciences in Erfurt.
From his marriage to Elsa, b. Oswald (1881–1937), his three children Egmund, Jan and Erdmuthe come from. When Stechow died in 1959, his only surviving son, Egmund, inherited the Hohenhaus.
