[D8547ZBQ], Legal Testimony, Thomas Alva Edison, September 1885

Editor's Notes

(Tomlinson's?) Notes for legal statement on patent application for improvements in telephones filed in US patent office Nov. 19, 1883; TAE originally proposed to Bergmann and Johnson that the undulating theory of sound transmission was incorrect and that a platina transmitter could be made; conversation led to experiments; TAE and Bergmann were in "constant association" in developing the platina transmitter, "each making suggestions & exchanging views" making the assignment of specific credit difficult; invention described in patent specifications "was a gradual growth of our joint efforts, & the result of our combined opinions & labor." [MARG.: Statement. I concur entirely in the statement of Mr. Edison of this date."]
