Hardcover. Etat : Good. No Jacket. 1st Edition. Xii, 119 + Large Catalog At End. Green Cloth, Lightly Worn But Most Of Fragile White Lettering Has Rubbed Away, No Fraying Or Stains. Hinges Solid. Signature Of "George F Haller / Sept 14 1910" On Front Endpaper, With Remains Of Tipped In Printed Paper Label Beneath The Signature, Of Which Only A "T" Remains, Possibly A Publisher's Note. In 1915 Cunningham (1889-1965) Started The Audio Tron Sales Company In San Francisco. Based On The West Coast, He Was In Direct Competition With Lee De Forest, A Leading Manufacturer Of Triodes Sold Under The Audion Brand. Before 1915, Triode Vacuum Tubes Were Spherical Or Shaped Like An Incandescent Light Bulb. Cunningham Took A Different Route. His Triode Tube Was Tubular And Had The Capability Of Being Double Sided. This Design Allowed Dual Filaments, Which Provided Longer Operating Life. Cunningham Was Able To Produce This Vacuum Tube In Large Numbers And Maintain Quality. The Rise In Amateur Radio Interest Was A Great Asset To Audio Tron Sales. This Design Proved Influential On Vacuum Tube Production, And Prompted De Forest To Come Up With A Tubular Audio. Another Important Design In The Audio Tron Tube Is The Use Of A Cylindrical Plate Instead Of The Typical Flat Plate In The Audion. The Cylindrical Plate Provided Better Gain And Tube Efficiency. This Design For The Audio Tron Was Probably Inspired By George Halle.In 1916, Elmer T. Cunningham And His Writing Partner George Haller Formed The Haller-Cunningham Company. The Main Purpose Was To Sell And Make Wireless Equipment. In Addition, Cunningham Provided Financial Backing To Otis B. Moorehead Late In 1915, To Start A New Vacuum Tube Company, Called Moorehead Laboratories Also Based In San Francisco, Ca. In July 1916 Otis Moorehead Marketed The Electron Relay Tube. This Vacuum Tube Was Similar In Appearance As Cunningham's Audio Tron. Like The Audio Tron Moorehead's Tube Would Cut Into De Forest's Tube Business On The West Coast And De Forest Would Take Legal Action On Moorehead As Well. Moorehead Would Later Make The First Military Tubes For The Us And United Kingdom During World War I. In 1919, The Radio Corporation Of America (Rca) Took Legal Action Against Cunningham For The Violation Of The Flemming And Deforest Patents. The Decision Made By The Us District Court For Northern California Proved Quite Favorable To Cunningham. By 1921, Audio Tron Manufacturing Company Started Slowly Changing Their Name To "E.T. Cunningham Inc." In Later Years After The Court Decision, Cunningham Played A Bigger Part In Rca's Business Activities. According To The Rca Publication " Rca A Historical Perspective" By 1931 The E.T. Cunningham Company Became An Integral Part Of Rca And Consolidated With The Rca Radiotron Company, Giving Rca Rights To The Use Of The Cunningham Brand. In Addition, Elmer T. Cunningham Became A Part Of The Rca Organization. In 1932 His Name Appears On Page 16 Of The August-September Edition Of "Music Trade Review" As President Of Rca Radiotron Division (Vacuum Tube Production And Distribution. By The Mid 1930S He Rose To The Position Of President Of Rca Manufacturing Division. Haller Was In A Responsible Position With Westinghouse In 1910. He Wrote The Use And Care Of Storage Batteries In 1916. He Became Vice President And General Manager Of Haller Cunningham Electric And In 1917 Was Traveling Throughout The U.S. Arranging For Installation Of Their Extensively Patented Wireless Equipment On Steamers. By 1923 He Was President Of The San Francisco Labor Council And That Year Became A Member Of The California Commission On Immigration And Housing. 56 Illustrations (illustrateur).
