- Description
- This is a Troemner Analytical Balance No. 10 with aluminum beam, and wooden case with glass sides. The inscription on the ivory scale reads “MADE BY / HENRY TROEMNER / FOR / ARTHUR H. THOMAS CO. / PHILA.”
- Arthur H. Thomas described this, in 1921, as “a world-famous balance of a construction original with Henry Troemner, Philadelphia, on designs suggested by Mr. A. A. Blair, and for twenty-five years perhaps the most widely used high-grade analytical balance in many industrial laboratories, particularly in the iron and steel industry. From the standpoint of sensitivity, simple construction and durability, we recommend this balance for continuous and precise analytical work.”
- A paper label, under the base at front, reads “J. RUSSEL MARBLE & CO., 18-20 Poster, St. WORCESTER, MASS.” This label is also marked: “This balance is the personal property of JOHN PUTNAM MARBLE purchased 11/5/1935.” John Putnam Marble (1897-1955) was a chemist with a Ph.D. from Harvard University, who worked with the Committee for the Determination of Geologic Time, of the National Research Council. He was also an Associate in Mineralogy of the Smithsonian Institution.
