[MRCA] Off topic? ID Radio Officer 10/2/1912

[Tom Chirhart]

I have a book, Manual of Wireless Telegraphy for the use of Naval Electricians 1911
Inside the front cover the owner wrote
John R. Churchill 10/2/12
503 W 169 St.
New York City or
C/O Marconi Co. Edison Bldg
Scratched out is
29 Cliff St. NYC

Anyone have a clue how I could get more info on this very early Radio Officer that worked for Marconi in the early days of radio... Any Sherlock Holmes types up to solving a great mystery?
Feel free to share with other groups...
