Marcelo Barbero was born in Madrid in 1904. Marcelo was trained by José Ramirez II, and gave José Ramirez III his initial lessons in guitar building. When Santos Hernandez died in 1943, Marcelo went to his widow to see about taking over her husband’s old shop. She employed Marcelo Barbero first to complete some guitars that Santos had left partially built, and then to make guitars for her. Marcelo Barbero trained Arcángel Fernández.
