Who was the first person to climb Denali?

The first person to successfully climb Denali (formerly known as Mount McKinley) was Hudson Stuck, who, along with Harry Karstens, Walter Harper, and Robert Tatum, reached the summit on June 7, 1913. Harper was the first to set foot on the summit, making him the first person to stand on the peak. Their expedition is considered a significant achievement in mountaineering history.
