Gilman’s Point, located on the crater rim of Mount Kilimanjaro, is the lowest of the three official summit points on the mountain. Sitting at an elevation of approximately 18,638 feet (5,681 meters), it was named in honor of Clement Gillman, a pioneering East African engineer and geographer.
Who Was Clement Gillman?
Clement Gillman was born in Spain on November 26, 1882, to an Anglo-Swiss father and a German mother. He was raised in Germany and educated in Switzerland, setting the stage for a life of travel and exploration.
In 1905, Gillman arrived in East Africa as a survey engineer working on the construction of the Central Railway. This marked the beginning of a lifelong connection with the region.
Gillman resided in East Africa for over 40 years. Despite the challenges of World War I and II—including a period of internment—his passion for science and exploration endured. In his later years, he served as a government water consultant and continued producing influential academic work until his death in 1946.
Gillman’s legacy is etched into East African history through his maps, publications, and pioneering fieldwork.
1909 Kilimanjaro Expedition
In the early 1900s, Mount Kilimanjaro presented a significant challenge for explorers. Limited technology made every ascent a test of endurance and ingenuity.
Gillman attempted his first climb in 1909, just a few years after arriving in Africa. While details of this expedition remain scarce—including the route taken and obstacles faced—he did not reach the summit. Nevertheless, this effort underscored his deep interest in Kilimanjaro’s topography and environmental significance.
1921 Kilimanjaro Expedition
In 1921, Clement Gillman led a major British scientific expedition to Kilimanjaro. The goal was not merely to summit, but to conduct geographical and environmental research on the mountain.
This ascent followed World War I, during which control of the region shifted from Germany to Britain, making this the first British-led climb under the new territorial administration.
On October 19, 1921, Gillman’s team launched their summit bid. Though they did not reach the mountain’s highest point, they successfully made it to the crater rim, where Gillman planted the Union Jack.
The point where he stopped—at 18,638 feet (5,681 meters)—was later named Gilman’s Point in his honor.
The Naming of Gilman’s Point
Though the location had been previously mapped by German explorers Fritz Klute and Eduard Oehler in 1912, it had remained unnamed.
Later, the site was formally designated Gilman’s Point in recognition of Clement Gillman’s contributions to the exploration and scientific study of Kilimanjaro and East Africa.
Although Gillman initially objected to the naming, he eventually accepted the tribute with quiet pride.
Gillman’s Legacy
Gillman passed away on October 5, 1946, while flying from Dar es Salaam to Moshi, within sight of Mount Kilimanjaro. In poetic fashion, it is said he died “with his pencil in his hand and his notebook on his knee.”
His contributions extended far beyond the slopes of Kilimanjaro:
- His hydrological surveys informed water management and infrastructure.
- His railway engineering work facilitated development across East Africa.
- His maps and academic publications remain foundational references today.
Scientific Precision on the Mountain
During his expeditions, Gillman used the Siedepunkt-Meßmethode—a method that calculates altitude using the boiling point of water.
Because water’s boiling point decreases by about 10°C per 3,000 meters of elevation, Gillman determined that at Gilman’s Point, water would boil at exactly 81.06°C—a brilliant example of science meeting adventure.
