Julius Jensen (psychiatrist)

from Wikipedia, the free encyclopedia

Julius Wilhelm Heinrich Jensen (born July 30, 1841 in Kiel , † April 24, 1891 in Charlottenburg ) was a German psychiatrist , brain researcher and insane asylum director. The " Sulcus intermedius primus" ("Sulcus Jensen", but especially in the English-speaking world as "Jensen sulcus", "Jensen's sulcus"), a cerebral furrow of the parietal lobes , which he first described in 1871, is named after him .

Life

After Jensen had completed his medical studies in Würzburg and Kiel in 1866 with a doctorate under Friedrich von Esmarch , he joined an East Prussian hunter battalion as a doctor in Prague and took part in the German War . Jensen was actually a surgeon , but when he and his unit came to East Prussia after the end of the war, the position of second doctor at the Allenberg Provincial Sanatorium near Wehlau had just become vacant. Jensen got the job and worked for a short time with his predecessor Karl Ludwig Kahlbaum and his student Ewald Hecker , whose work on the differentiated pathology had a strong influence on him. When Jensen soon afterwards de facto had to represent the sick director, he introduced the principles of “ no restraint ” in Allenberg .

In 1868, Hermann Wendt became director in Allenberg, with whom Jensen became friends and who enabled Jensen to devote himself to numerous scientific works on brain anatomy in addition to his work as a prison doctor. Jensen carried out measurements and drawings of the brain surface mainly with a drawing machine he had developed. As Wendt's successor, he finally managed the Allenberg insane asylum himself from 1875. Here he enforced that only the treatment of the curable sick remained free of charge, but the poor associations had to pay for the treatment of the incurable poor . In doing so, he ultimately ensured that the mentally ill were admitted to the institution more quickly, because it promised better prospects of recovery. He also set up a rural insane colony and directed the construction of a new insane asylum in Kortau .

In 1885, Jensen took over the city asylum seeker in Dalldorf near Berlin, but a brain disease put an early end to this activity in 1887. After suffering several "paralytic" and "epileptic" attacks in 1890, he died on April 24, 1891.
