Drafting Pens and Pencils
Pencils

An image showing a variety of drafting pens and pencils from the Division of Medicine and Science.

Pencils also have changed over time. This page shows one example of slate pencils as well as boxes of the more familiar wood-encased pencils. The collections have both an early instance of a mechanical pencil and a 20th-century example, the latter with a famous connection. Draftsmen needed pencil leads to insert into other drawing instruments, and one engineer even donated his metal pencil box.
