Giampiero Vitelli began his career as a designer at a young age, creating significant and innovative pieces for home furnishings while studying new production technologies. In 1961, he began collaborating with Titina Ammannati, and together they worked in the private construction, renovation, furniture, and design sectors, making significant contributions to the success of Italian design. They collaborated with both Italian and foreign companies; in particular, until 1970, they worked with Rossi of Albizzate, for whom they defined both production and design. Their works have been published in design magazines and books.
