Factotum: the jack-of-all-trades block

To most people, a factotum is a person of many skills, a general assistant who can turn a hand to any task. The word comes from Latin: facere (to do) and totum (the whole thing). It describes someone indispensable because they are willing and able to do whatever needs doing.

In early European printing, a factotum was not a person but a block of wood or metal. It was a large, ornamental frame, often decorated with vines, flowers, or geometric borders, designed to mark the start of a chapter or section in a book. The crucial feature was an empty space in the center, large enough to accommodate any single letter. Rather than cut separate decorative blocks for every letter that might begin a chapter, printers used one versatile factotum frame repeatedly, inserting different letters into the central cavity each time.

The shift in meaning reflects the same principle of adaptability. Just as the printing block performed many different functions by accepting different letters, a factotum person became anyone capable of filling many different roles. The metaphor is explicit: both are tools designed for flexibility, both do the whole job by adapting their core function to whatever comes next.

Factotums were most common in the 16th and 17th centuries, when hand-cut types were expensive and printers valued any device that reduced the need for new blocks. A printer might own dozens of factotums in different sizes and styles but with the same underlying design: frame plus cavity. The technique declined as printing technology improved and type became cheaper to produce, but the word survived in general use, detached from its technical origin.
