- Description
- Warren P. Valentine began making refractometers when World War I limited the import of European instruments into the United States. By 1920 the National Bureau of Standards reported that Valentine's Precision Refractometer was “the most accurate Abbé refractometer we have so far tested.”
- In 1928, Valentine received the Edward Longstreth Medal of the Franklin Institute in “consideration of the meritorious work shown in the improvement of the mechanical and optical parts of the Abbé refractometer, thereby increasing its accuracy.”
- This example is marked “VALENTINE REFRACTOMETER NO. 591 INDUSTRO-SCIENTIFIC CO. PHILADELPHIA.” The National Bureau of Standards transferred it to the Smithsonian in 1965.
