In September of 1898, Mr. Bentley L. Rinehart, who had worked for Mr. Johnson before, was given the job of designing and installing an electroplating plant. This was completed in March of 1899, and turned out to be an excellent investment. This not only avoided the necessity of revealing secrets to outside vendors, but made it possible to develop progressively finer results.

Between 26 Dec 1901 and 15 Jan 1902:
"I spent a few days in the laboratory in Philadelphia. I met the Manager of the Victor Talking Machine Co., Mr. Douglas[s]. Also lunched once or twice with E. R. Johnson. Bentl[e]y Rhinehart happened to be in Phila. and I had some talks with him also."
