Designed for Linotype in 1972 by Matthew Carter, Shelley Script can be seen as a companion for Snell Roundhand, the typeface he designed in 1966, which was notable because it connected lowercase letters like actual cursive handwriting. Snell and Shelley both were proponents of roundhand penmanship, characterized by a flowing, open style. The variations of stroke width evident in their styles are due not to the movement of a soft-tipped writing instrument or calligrapher’s brush, but the pressure on a steel-nibbed pen which can be both pulled and pushed.
Despite their shared advocacy of roundhand penmanship, Snell’s and Shelley’s individual styles were markedly different, and Carter is faithful to both in his typefaces. The Shelley typefaces generally have more activity in their uppercase flourishes, and while both have small x-heights relative to their ascenders and descenders, the descenders on the Shelley Script are proportionately longer than those on the Snell.
When Carter and Mike Parker established the Bitstream typeface foundry in 1981, they couldn’t distribute Shelley Script because Linotype owned the trademark; Bitstream therefore released an identical typeface called English 111™.
