Oh yes, it was a famous expedition and when the first results in the Olduvai Gorge caused a sensation when the German neurologist and paleontologist Professor Wilhelm Katvinckel in 1911 became the first Europeans to enter the gorge after encountering the remains of the long-extinct three horse hurricane (Hipparion). In 1913 the Berlin researcher Hans Rekk followed him and found the first fossil hominin, about 20,000-year-old Homo sapiens skull. Thank you @gavvet
