On June 26, 1921 the influential choreographer and writer Filipe Oihanburu (also spelled Philippe Oyhamburu) was born in Argelèrs de Gasòst (Argelèrs de Gasòst in Occitan) in Béarn/Biarn.
At age 3 his family moved to Montevideo, Uruguay, and in 1930 relocated to Paris, but he always took an interest in his Basque family roots (his father was from Biarrritz, and while his mother was from Béarn, she also had Basque roots) and started learning Euskara, the Basque language, at an early age while vacationing on the coast of Lapurdi. He also took a growing interest in dance, and on moving to Biarritz, in 1944, he took over the direction of the Olaeta ballet company. In 1945 it changed its name to Oldarra and for much of the next decade offered a plethora of performances. In 1953 he founded the professional music and dance group Etorki, which eventually traveled the world promoting Basque music and dance.
He combined his work as a choreographer with writing books, mostly on Basque politics and culture. More recently, he wrote his memoirs about living in Nazi-occupied Paris during the 1940s.
