Jens Jetsmark Biography

Jens Esmark (1763–1839) was an expert mountain climber and professor of mineralogy who contributed to many of the initial discoveries and conceptual analyses of glaciers, specifically the concept that glaciers had covered larger areas in the past. In August 1801 Esmark was the first person to ascend Snøhetta, highest in the mountain range Dovrefjell in southern Norway. The same year he lead the first expedition to Bitihorn, a small mountain in the southernmost outskirts of Jotunheimen, Norway. In 1810 he was the first person to ascend the mountain Gaustatoppen in Telemark, Norway. Professor Esmark theorized in 1824 that glaciers had once been larger and thicker and had covered much of Norway and the adjacent sea floor. He also attributed erratic boulders and moraines to glacial transportation and deposition. He first recognized glaciers as a powerful agent of erosion that had carved the Norwegian fjords. Professor Esmark was also an important figure in the history and cultural heritage of mineralogy. On the island of Løvø, Norway, his son, Hans Morten Thrane Esmark, found the first specimens of a black mineral, thorite, from which the element thorium is derived. His son also provided him with a new mineral which he found in Arendal, Norway. In 1806 he named datolite, from the Greek word meaning "to divide". This was a reference to the granular structure of the first specimens studied. In 1825, he was elected a member of the Royal Swedish Academy of Sciences.)

The Best Poem Of Jens Jetsmark

Fædrelandssang

Duftende Enge og kornrige Vange,
sølverblaae Vover om skovkranste Kyst,
gyngende Snekker og jublende Sange,
det er vort Fædrelands Vælde og Lyst.

Tidt pløjer Dansken de fjerneste Bølger,
stundom han færdes i fremmede Land;
stedse dog Mindet om Danmark ham følger,
tryller ham sødt til dets elskede Strand.

Høit have Konger ved store Bedrifter,
Helte ved kjæk og berømmelig Færd,
Skjalde ved Sange, og Vise ved Skrifter
hævdet vort Danriges ældgamle Værd.

End troner Kraften i Egenes Skygger,
Frihed end boer under Nordboens Tag,
Ætten af Kæmper vor Arne betrygger,
Retfærd omsvæver vort Banner og Flag.

Retfærd og Frihed vort Løsen monn' være:
Dem ikkun hylder den nordiske Mand!
Fred om vor Hytte, og Skjold om vor Ære!
Himlen velsigne vor Drot og vort Land!
