His brother was the naturalist Franz Xaver Rudolf von Höhnel (1852–1920). Von Höhnel made two expeditions into East Africa into the Mount Kenya and Kilimanjaro regions.
Early life
Höhnel was born in Pressburg (now Bratislava), the youngest of four sons of Dr. Gottfried Ritter von Höhnel (d. 1868), who moved from Trieste in 1864 to Pressburg to work as a finance director for the coastal region. He was admitted to the Imperial and Royal Naval Academy in Fiume in 1873, joining the Austro-Hungarian Navy as a naval cadet at Pola. He travelled widely and in 1887 he was promoted to naval lieutenant. He worked mainly from Pola and Zara, working with the hydrographic office at Pola. He sailed at various times with the Crown Prince Rudolf and his wife, Princess Stéphanie of Belgium, on the yacht Greif. He also sailed with Prince Leopold of Bavaria and the zoologist Alfred Brehm. His encounter with the crown prince who knew Count Teleki and the plan for an expedition to East Africa led to his being invited to join.<ref>Template:Cite journal</ref>
Journey with Teleki 1887–1888

Höhnel was the second-in-command of Count Sámuel Teleki von Szek's expedition to Northern Kenya in 1887–1888. He and Teleki were the first Europeans to see Lake Turkana, which they named Lake Rudolf after the expedition's patron Crown Prince Rudolf of Austria, and also Lake Stefanie, named after Prince Rudolf's wife Princess Stéphanie of Belgium. Höhnel acted as the expedition's cartographer, scientist, and diarist. Teleki and Höhnel made numerous observations on the climate, flora, and fauna of the territories visited and collected more than 400 ethnographical objects, most of them from Maasai and Kikuyu tribes. Their observations provided important contributions to ethnographical knowledge. The scientific results of the journey were published by Höhnel in several articles and in a book written in German and translated into Hungarian and English, titled The Discovery of Lakes Rudolf and Stefanie (1892).<ref>Balàzs Borsos, "Whose merit is it anyway?

Journey with Chanler 1892–1894
Between 1892 and 1894, Höhnel explored the territory in the vicinity of Mount Kilimanjaro with American magnate William Astor Chanler.<ref name="google">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> They proceeded inland from the coast, mapping the north-eastern part of the Mount Kenya massif,<ref>Kotrba, Franz, "William Astor Chanler (1867–1934) und Ludwig von Höhnel (1857–1942) und Afrika."

They were the first Europeans to come into contact with the Tigania, the Igembe Meru and the Rendille people in this region (Carl Peters had passed to the south in 1889). On 30 January 1893, they were attacked by some 200 warriors of the Wamsara (a subgroup of the Meru), who retreated after killing three porters.<ref name = "Imperato">Imperato, P. J. (1998).

During this expedition, Höhnel and Chanler explored over Template:Convert of previously unmapped territory, fixed the exact position of Mount Kenya, and viewed the Nyambeni hills, Chanler's Falls, and the Lorian Swamp, and mapped the course of the Ewaso Ng'iro River. Five specimens donated to the Smithsonian were previously unknown species, including two species of butterflies, two species of reptiles, and Chanler's Mountain Reedbuck.<ref name = "Imperato"/>Template:Rp
Later life
After recovering from his injuries, Höhnel became an officer in 1896 on board the corvette SMS Donau,<ref>SMS Donau</ref> and traveled in 1897 to the Mediterranean and along the coast of West Africa south to Cameroon, then across the Atlantic to the Caribbean, and to New York and Newport, Rhode Island. During the trip, the ship's captain suffered a heart attack and Höhnel was made provisional commandant until June 1898. Also on this voyage, he met the future US president Theodore Roosevelt, who was then in his words the 'much feared' police commissioner of New York. After this, Höhnel was assigned as an officer of the deck to the central battery ship Template:SMS, whose executive officer was Commander Anton Haus, the future commander of the Austro-Hungarian Navy.
In 1899 Höhnel became Emperor Franz Joseph's aide-de-camp and later (1905–09) led an official Austro-Hungarian delegation to Emperor Menelik II of Ethiopia. He also commanded the Austro-Hungarian torpedo cruiser Template:SMS in a voyage to Australia and Polynesia in the summer of 1905. Höhnel was instrumental in introducing the chamois into New Zealand, negotiating the acquisition in 1905 of six does and two bucks from Neuberg in Austria. They finally arrived in New Zealand on board the SMS Turakino in 1907. He was the commanding officer of the armored cruiser Template:SMS and the commander of the navy yard in Pula.

In February 1907, he submitted a formal request to the navy for permission to marry Valeska von Ostéren (1870–1947) (permission was required as per Austrian naval regulations). However, permission was denied, because it was discovered that Valeska's brother had published an anti-Jesuit novel<ref>Friedrich Werner von Ostéren, Christus nicht Jesus: ein Jesuitenroman, Egon Fleischel and Co., Berlin, 1906</ref> in 1906 which offended the powerful Archduke Franz Ferdinand.<ref>Ildiko Simanyi, "Ludwig Ritter von Höhnel (1857–1942): Leben und Wirken." Master's thesis, University of Vienna, 1988.</ref> Höhnel was eventually forced to choose between his marriage and his naval career. He married Valeska in August 1909 and subsequently resigned from the rank of captain. In 1912 he was promoted to rear admiral, probably in recognition of his duties as aide-de-camp to the emperor.<ref name = "Imperato"/>Template:Rp

Post-naval career
Höhnel wrote an autobiography centered on the turbulent years preceding the fall of the Austro-Hungarian monarchy, providing insights into African exploration, the Austro-Hungarian Navy, and prominent personalities of the Habsburg court, including Admiral Hermann von Spaun, Admiral Maximilian Daublebsky von Sterneck, and Rudolf Montecuccoli. The complete manuscript remained in the possession of the family of William Astor Chanler for many decades and was finally published in 2000.<ref>Ludwig von Höhnel, John Winthrop Aldrich, Over Land and Sea: Memoir of an Austrian Rear Admiral's Life in Europe and Africa, 1857–1909, Holmes & Meier, 2000</ref><ref>Ronald E. Coons and Pascal James Imperato, eds. Over Land and Sea: Memoir of an Austrian Rear Admiral's Life in Europe and Africa, 1857–1909. Holmes and Meier, New York, 2000.</ref>
Höhnel later wrote a 56-page account of his service as aide-de-camp to the Emperor Franz Joseph I of Austria, which was never published.<ref name="worldcat">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
He died in Vienna in March 1942 and is buried in the Vienna Central Cemetery.<ref name = "Imperato"/>Template:Rp
