About the Photos

Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive. (To query the database click here.) They are adjusted, restored and reworked by your webmaster in accordance with his aesthetic sensibilities before being downsized and turned into the jpegs you see here. All of these images (including "derivative works") are protected by copyright laws of the United States and other jurisdictions and may not be sold, reproduced or otherwise used for commercial purposes without permission.

How does it work?

Food Texture and Viscosity: Concept and Measurement

Loaf Volume Meter
This apparatus consists of a metal box connected through a rectangular chute to a hopper containing rapeseed. A loaf of bread is placed in the box, which is closed, a slide in the chute is pulled out, and the rapeseed is allowed to fill the box. A calibrated scale on a Pyralin face of the volumeter column gives the direct reading of the volume of the bread in cubic centimeters. This device is widely used in the baking industry to measure loaf volume, which is one index of quality of the loaf.


Perhaps I'm ignorant of early 20th Century baking standards, but the loaves appear to be twice the size of our current standard sandwich bread loaf.

How did the bread scientists...

... do their job before the invention of the bread-o-nometer?

In the eye of the beholder

To me, the lady in the bread-measuring lab is much prettier than any of the bathing beauties seen in recent photos.

The Very First

... Funnel Cake.
