Ali Salem Hamudi Mohamed - Yahdih, was born in 1955 in El Aaiún (Western Sahara). He completed his secondary schooling in the "Spanish" Sahara. A scholarship allowed him to enrol at the Universidad de la Peninsula in 1975, but Morocco's invasion of the Sahara led him to return to the city of his birth and go into exile with his people, participating in the resistance and helping to organise the Tindouf Refugee Camps (Algeria). In 1980, the Polisario Front and the Government of Cuba offered him the opportunity to study Architecture at the University of Havana. On his return to the Camps in 1985 he worked for the SADR's Department of Construction. He designed more than twenty public buildings, including town halls, schools and nursery schools, and also collaborated with international aid organisations to build hospitals and training colleges. All of these buildings were built collectively by the Saharan people. ;In 1999 he emigrated to Spain. His family joined him five years later.
