Carlos Iraldi is a doctor, but his knowledge and above all his enormous curiosity have led him to stand out in different branches of art such as writing, painting and photography. His fame, however, is due to the ingenious instruments he invented and which have served as support for several shows by the Les Luthiers ensemble.
