Explanation:

Zebulon Montgomery Pike was an American brigadier general and explorer for whom Pikes Peak in Colorado was named.

Zebulon Montgomery Pike (January 5, 1779 - April 27, 1813) was an American explorer and military officer (he served in the War of 1812).

Pike tried to find the source of the Mississippi River and also explored the Rocky Mountains and southwestern North America. Pike's Peak in Colorado is named for him.

Considering his heroic actions in the War of 1812, Zebulon Pike was remembered as a military hero. And in the 1850s settlers and prospectors in Colorado began calling the mountain he encountered Pike's Peak, a name which stuck.
