He attended classes on natural history and geography at the University of Vienna, and in 1885 was part of an Austrian exploratory expedition of the Congo Basin under the direction of Oskar Lenz. However, because of serious illness, Baumann would be forced to leave the expedition prior to its conclusion. In 1886, he conducted ethnographical research on the island of Fernando Po. When he returned to Europe, he received his doctorate from the University of Leipzig (1888).[1]

Baumann is best known for his exploration of the interior of German East Africa (present-day Tanzania, Rwanda and Burundi), and for producing maps of the region. In 1888, with geographer Hans Meyer, he explored the Usambara region, with designs of continuing on to Mount Kilimanjaro. The two explorers' progress was stopped, however, due to ramifications associated with the so-called "Abushiri Revolt" (1888–89). Within a matter of days Baumann and Meyer were captured and held as prisoners. According to the British Rear-Admiral Edmund Fremantle:

'They had been robbed, stripped, and subjected to every indignity, but except that they have lost all, including their instruments and observations, they do not seem much the worse'.[2]

Only after a large ransom was paid to rebel leader Abushiri ibn Salim al-Harthi were the two men released.[3]

Baumann's most celebrated mission was the 200-member "Maasai Expedition" of 1891–93. On the expedition, he performed map-making duties, and was the first European to enter Rwanda (1892).[1] He was also the first European to visit Lake Eyasi,[4] Lake Manyara,[5] and Ngorongoro Crater.[6] On the expedition, he explored the headwaters of the Kagera River, which he reasoned, was the true source of the Nile.[7][8] As a result of the journey, he produced a book titled "Durch Massailand zur Nilquelle" (By Massailand to the Source of Nile, 1894) .

In 1896, Baumann was appointed consul to Zanzibar by the Austro-Hungarian government. However, he died a few years later of an infectious disease at the age of 35.[1] In 1902 the thoroughfare Baumannstraße, in the district of Landstraße (Vienna), was named in his honour.[9] The highest point of the German protectorate Togoland was called the Baumannspitze (present-day Mount Agou in Togo).[10]
