Jonas Charles Hermann Freund (1808 – 29 December 1879)[1] was an Austrian-British physician, known as the co-founder of the German Hospital in London.[2] [3]
Born to a Jewish family in Bohemia, Freund received a medical degree at the University of Vienna. In London in 1843 he was a co-founder of London's German Hospital, which opened in October 1845. He was Physician in Charge of the hospital until about 1850. The evidence suggests that he was Karl Marx's doctor.[4] Freund was Deputy Inspector-General of Army Hospitals in the Crimean war and an army surgeon.[1]
In London in 1846 he married Prussian-born Louise Amalie Rüdiger, who became a prominent editor and author under the pseudonym "Amelia Lewis". She was an inventor and a campaigner for women's rights.[4] Their son John Christian Freund became a prominent editor and publisher.
