Henry Hudson reaches the river that would later be named after him – the Hudson River.

Explorer Henry Hudson reaches the vast North American river later named the Hudson River.
On September 13, 1609, English navigator Henry Hudson sailed into a wide river on present-day New York’s coast. Sailing under the Dutch East India Company, Hudson sought a Northwest Passage to Asia. He documented the river’s depth and potential for trade, noting its calm waters and fertile banks. Hudson’s exploration laid the foundation for Dutch colonization in the region. He anchored near what would become Manhattan, establishing the first European contact with local Lenape tribes. Although the passage to Asia proved illusory, the river became a vital artery for commerce. Hudson’s name would be immortalized on maps, shaping future settlements along its shores.

Mackinder, Ollier, and Brocherel complete the first recorded ascent of Batian, the highest summit of Mount Kenya at 5,199 meters.
On September 13, 1899, British geographer Halford Mackinder, Swiss guide César Ollier, and French explorer Brocherel reached the summit of Batian, the highest peak of Mount Kenya. Their expedition combined scientific observation with mountaineering skill in one of Africa’s most challenging environments. The climbers navigated glaciers, scree slopes, and steep rock faces to conquer the 17,058-foot summit. This achievement marked a landmark in the age of exploration and expanded Western knowledge of East Africa’s interior. Mackinder’s detailed reports contributed to early geographic and geological studies of the region. The ascent inspired subsequent explorers and remains a celebrated event in climbing history.
