According to an article in the San Jose Evening News (August 20, 1897), Charles Nash was a director of an earlier mining venture,
Rodman-Morrell Mining and Milling Company, incorporated in San Jose that month, in which he invested an initial $5100.
Herbert Lang was the author of Metallurgy, Volume I (1911), and is described by references in an article, "Direct Steel Process
Maneuvers Exposed" (Santa Cruz newspaper, April 12, 1921) as "a skillful metallurgist and an honorable man. I have had the
pleasure of publishing many valuable technical articles written by him." (T. A. Rickard, president and editor of the Mining
and Scientific Press of San Francisco). Another reference writes, "We consider Herbert Lang a metallurgist of the highest
caliber." Lang and his wife were living in Oakland and Berkeley during the time of his involvement with the Nashes; they appear
from letters to have originally stayed at the Nash home before moving to a hotel in Oakland, and then moving to a rental in
Berkeley. It is not clear whether he is the same person as Herbert O. Lang or Herbert V. Lang. What became of him after the
correspondence stops in 1922 is not known.
