Surely you didn’t think a butler or diner would brush fallen bread crumbs off the bleached white tablecloth onto the floor? Perish the thought! Instead, some clever person invented the table crumber, or simply, the crumber.
The crumber came in many forms: a small brush and pan, a tiny brush on its own (which sweeps crumbs into a waiter’s hand), and a flat metal scraper or blade with or without a handle. As seen in these examples, the materials widely varied but were almost always beautifully designed as befitting eras of fine, upper crust (pun intended) dining.
