A RARE AND IMPORTANT PORTRAIT OF JACQUARD, EXECUTED ON THE PROGRAMMABLE LOOM BEARING HIS NAME

The present full-length portrait depicts Jacquard facing slightly left, seated in his workshop, holding a drafting compass in his hand. On a table is a model of a Jacquard loom, and the punch cards used to create designs in woven fabric. A workbench and tools also appear in the background, along with other materials related to weaving. In the upper left is a window with a hole the size of a musket ball in one of the panes.

When considering the birth of the programmable computer, the credit is usually given to Charles Babbage. Jacquard, however, conceived of developing a semi-automatic tone-selection device, which would be integrated onto the loom, resulting in quicker production and more intricate patterns. Jacquard's punch-card system worked much in the same way as a fax machine: each punch in the card directed a black or a white thread into the headstock of the loom, pin-pointing the desired thread into place.
