William Katavolos, Ross Littell and Douglas Kelley were an American design trio who met at the Pratt Institute in New York and began working together in 1949. Their partnership developed through Laverne Originals, where they designed furniture, textiles and tableware with a focus on structural clarity, refined proportions and modern industrial materials. Their T-Chair became one of the most significant examples of mid-century American furniture design, helping define the legacy of their collaboration.
