Carol Twombly (born 1959) is an Americancalligrapher and typeface designer who has designed many typefaces, including Trajan, Myriad and Adobe Caslon. She worked as a type designer at Adobe Systems from 1988 through 1999, during which time she designed, or contributed to the design of, many typefaces. She retired from type design in early 1999, to focus on her other design interests, involving textiles and jewelry.
Twombly attended and graduated from the Rhode Island School of Design (RISD) where she first studied sculpture, and later changed her major to graphic design. She credits her professors Charles Bigelow and Kris Holmes, whose studio she worked in, for her inspiration and stimulating her interest in typography. At Stanford University Twombly was one of only five people to graduate from the short-lived digital typography program.
