letterfounder

A letterfounder is a craftsperson who designs, cuts, and casts individual metal letters, numerals, and symbols for use in letterpress printing. The founder's output, called type, consists of small metal slugs, typically made from lead alloy, each bearing a single character in relief on its face. These pieces are assembled into forms on the composing stone, inked, and pressed onto paper to create printed impressions. The work requires precision at multiple stages: pattern-making, mold creation, casting, and finishing.

The metal used in type founding is almost always a lead-tin-antimony alloy, chosen because it casts sharply, wears well under repeated impression, and can be melted down and recast when type becomes worn or obsolete. The antimony content (typically 10 to 20 percent) hardens the metal; tin improves flow and castability. A letterfounder maintains stock in multiple sizes, running from 6 point to 72 point and beyond, with different weights (roman, italic, bold) and styles within each size.

The traditional letterfounder's craft involved cutting a steel punch (the master pattern) by hand or with engraving tools, striking that punch into a copper or brass strike (the intermediate mold), and then pouring molten metal into justified molds made from the strike. The cast type piece, the sort, emerges with three essential dimensions: height (fixed at 0.918 inches in Anglo-American practice), width (varying by character), and depth (the distance from face to back). Each sort required trimming, planing, and inspection before being fit for press work.

The decline of hand-founding

By the mid-nineteenth century, mechanical type-casting machines (notably the Linotype and Monotype systems) displaced hand letterfounders in many shops, though independent founders survived longest in areas demanding specialty faces or non-standard characters. The rise of phototypesetting in the mid-twentieth century, followed by digital type, reduced foundry work to a marginal craft. Today, traditional letterfounders are rare; those who persist serve fine printers, book artists, and historical restoration projects.

The letterfounder's name derives from the founding process itself, the casting of metal into form. In printing terminology, the letterfounder occupied a distinct role from the compositor (who assembled type) and the pressman (who printed with it). A well-stocked foundry might hold hundreds of thousands of individual sorts, organized by typeface family, size, and character. The quality and consistency of type casting directly affected the crispness and uniformity of printed work, making the founder's skill essential to the trade's reputation.
