Typefounder → It is formed from "type" (from Greek "typos", meaning a model or impression) and "founder" (from Old French "fonder", meaning to melt or cast). A typefounder is someone who creates or casts types for printing, essentially making models for letters and characters.
Think of a 'model' ('type') being 'cast' ('founder') to create letters for printing — that's what a typefounder does.
