Peter Lassen, later known in Spanish as Don Pedro Lassen, was a Danish-born Californian ranchero and gold prospector. Born in Denmark, Lassen immigrated at age 30 to Massachusetts, before eventually moving to California. In California, Lassen became a Mexican citizen and received the vast Rancho Bosquejo from Governor Manuel Micheltorena. He is best known as the eponym of Lassen County, California, Lassen Peak, and Lassen Volcanic National Park.
