Stokowski DiscsPresented to Library of Congress\n\nIn a ceremony at the Library on January29,a representative of BellLaboratories presented to_Assistant Librarian of Congress forResearch Services John C.Broderick a collection of historic high-fidelity and stereophonic recordings of Leopold Stokowski conduct-ing the Philadelphia Orchestra.  \nThe unique recordings,made in 1931 and 1932 by Bell Labs,areconsidered to be the best quality recordings made of the PhiladelphiaOrchestra during the period when it was considered to be at the peakof its musical powers.The first known stereophonic recordings oforchestral music,they were made on electrical sound recording andplayback systems invented by Bell Labengineers.  \nThe recordings were part of a Bell Labs project aimed at improvingthe quality of recorded and amplified sound transmitted over thetelephone network.In 1925,when they introduced the first electricalrecording system,their contributions to the technology includedvacuum tube amplification,the condenser microphone,electricalloudspeakers,electrical recording and reproduction techniques,the33/r.p.m.standard for disc recording,Vinylite record discs,goldsputtering techniques to make record masters,a lightweight pickupfor early hi-fi records,and the “air advance ball”method of position-ing the recording head precisely above the wax master.They alsoinvented an acoustical sound reproduction system which RCAmanufactured and sold as the Orthophonic phonograph.  \nIn accepting the Stokowski recordings from Bruce E.Strasser,director of public relations for the Bell Laboratories,Mr.Broderickmentioned how important to the Library is the work of AlexanderGraham Bell and the pioneering research and development of thepeople working in and for the laboratories that bear his name.TheLibrary has the notebooks and papers of Alexander Graham Bell,including the first drawing in which he sought to conceptualize thetelephone.The Library also has sound recordings cut,molded,and  \nArthurC.Keller  \nstamped using the various techniques and materialsdeveloped by Bell Laboratories.The Stokowskirecordings,he said,are a welcome addition to theLibrary's collections of the first stereophonicrecordings.  \nArthur C.Keller,an engineer now retired fromthe laboratories,described the developments inrecording technology that resulted from the BellLaboratories'efforts to improve telephone commun-ications.Some 6,000 recordings were made duringthese engineering studies,of which about 700 con-tain music of historic value.There are 128 discs ofStokowskimade at the Academy of Musicin Philadel-phia,others done at the Roxy Theater in New York,others of the Princeton organ and musicians such asGeraldine Ferrar,Mischa Elman,and Yasha Heifitz.  \nThe Library of
