Tango has also affected Uruguayan culture, especially during the 20th century, particularly the '30s and '40s with Uruguayan singers such as Julio Sosa from Las Piedras. When the famous tango singer Carlos Gardel was 29 years old he changed his nationality to be Uruguayan, saying he was born in Tacuarembó, but this subterfuge was probably done to keep French authorities from arresting him for failing to register in the French Army for World War I. Gardel was born in France and was raised in Buenos Aires. He never lived in Uruguay.Bocaz, Luis (March 1986).  "Tango Time" , UNESCO ''Courier'', p. 11. Nevertheless, a Carlos Gardel museum was established in 1999 in Valle Edén, near Tacuarembó.
