Raúl Rosarivo
Raúl Mario Rosarivo was an Argentine typographer, researcher, designer, poet, painter, and illustrator, known for his work in the analysis of the Gutenberg Bibles. He held the position of General Director of the Buenos Aires Provincial Graphic Workshops.
Rosarivo, in his Divina proporción tipográfica, first published in 1947, analyzed Renaissance books with the help of compass and ruler and described the use of the "número de oro", by which he meant the ratio 2:3, in books produced by Gutenberg. According to Rosarivo himself, his work and assertion that Gutenberg used the "golden number" to establish the harmonic relationships between the diverse parts of his printed works, was analyzed by experts
at the Gutenberg Museum and re-published in the Gutenberg Jahrbuch, its official magazine.
