  Edisonhimselfwasinuniversalrequestandthesubjectofmuchadulation,butaltogethertoobusyandmodesttobespoiledbyit。Onceinawhilehefeltithisdutytogooverthegroundwithscientificvisitors,manyofwhomwerefromabroad,anddiscussquestionswhichwerenotsimplythoseoftechnique,butrelatedtonewerphenomena,suchastheactionofcarbon,thenatureandeffectsofhighvacua;theprinciplesofelectricalsubdivision;thevalueofinsulation,andmanyotherswhich,unfortu-

  natetosay,remainasesotericnowastheywerethen,everfruitfulthemesofcontroversy。

  Speakingofthosedaysornights,Edisonsays:

  Ihadalibraryatthetopofthehouse,andRemenyicameupthere。Hewasinagenialhumor,andplayedtheviolinformeforabouttwohours——$2000worth。

  TheorganizationoftheEdisonElectricLightCompanywentbackto1878;butuptothetimeofleasing65FifthAvenueithadnotbeenengagedinactualbusiness。Ithadmerelyenjoyedthedelightsofanxiousanticipation,andtheperilouspleasureofbackingEdison\'sexperiments。Nowactiveexploitationwasrequired。Dr。NorvinGreen,thewell-knownPresidentoftheWesternUnionTelegraphCompany,waspresidentalsooftheEdisonCompany,butthepressingnatureofhisregulardutieslefthimnoleisureforsuchcloseresponsiblemanagementaswasnowrequired。Earlyin1881Mr。GrosvenorP。

  Lowrey,afterconsultationwithMr。Edison,prevaileduponMajorS。B。Eaton,theleadingmemberofaveryprominentlawfirminNewYork,toacceptthepositionofvice-presidentandgeneralmanagerofthecompany,inwhich,asalsoinsomeofthesubsidiaryEdisoncompanies,andaspresi-

  dent,hecontinuedactivelyandenergeticallyfornearlyfouryears,acritical,formativeperiodinwhichthesolidityofthefoundationlaidisattestedbythemagnitudeandsplendorofthesuperstructure。

  ThefactthatEdisonconferredatthispointwithMr。Lowreyshould,perhaps,beexplainedinjusticetothedistinguishedlawyer,whoforsomanyyearswastheclosefriendoftheinventor,andthechiefcounselinallthetremendouslitigationthatfollowedtheefforttoenforceandvalidatetheEdisonpatents。

  AsinEnglandMr。EdisonwasfortunateinsecuringthelegalassistanceofSirRichardWebster,afterwardLordChiefJusticeofEngland,soinAmericaitcountedgreatlyinhisfavortoenjoytheadvocacyofsuchamanasLowrey,prominentamongthefamousleadersoftheNewYorkbar。BorninMassachusetts,Mr。Lowrey,inhisearlierdaysofstraitenedcircumstances,wasaccustomedtodefraysomeportionofhiseducationalexpensesbyteachingmusicintheBerkshirevillages,andbyacuriouscoincidenceoneofhispupilswasF。L。Pope,laterEdison\'spartnerforatime。LowreywentWestto“BleedingKansas“withthefirstGovernor,Reeder,andbothwereactiveparticipantsintheexcitingscenesofthe“FreeState“waruntildrivenawayin1856,likemanyotherfree-soilers,bytheactsofthe“BorderRuffian“legislature。ReturningEast,Mr。LowreytookuppracticeinNewYork,soonbecomingeminentinhisprofession,andupontheaccessionofWilliamOrtontothepresidencyoftheWesternUnionTelegraphCompanyin1866,hewasappointeditsgeneralcounsel,thedutiesofwhichposthedischargedforfifteenyears。Oneofthegreatcasesinwhichhethustookaleadinganddistinguishedpartwasthatofthequadruplextelegraph;andlaterheactedaslegaladvisertoHenryVillardinhisnumerousgrandioseenterprises。LowreythuscametoknowEdison,toconceiveanintenseadmirationforhim,andtobelieveinhisabilityatatimewhenotherscouldnotdetectthefireofgeniussmoulderingbeneaththemodestexteriorofagauntyoungoperatorslowly“findinghimself。“ItwillbeseenthatMrLowreywasinapeculiarlyadvantageouspositiontomakehisconvictionsaboutEdisonfelt,sothatitwasheandhisfriendswhoralliedquicklytothenewbannerofdiscovery,andlenttotheinventortheaidthatcameatacriticalperiod。InthisconnectionitmaybewelltoquoteanarticlethatappearedatthetimeofMr。Lowrey\'sdeath,in1893:“OneofthemostimportantserviceswhichMr。LowreyhaseverperformedwasinfurnishingandprocuringthenecessaryfinancialbackingforThomasA。Edisoninbringingoutandperfectinghissystemofincandescentlighting。Withcharacteristicpertinacity,Mr。Lowreystoodbytheinventorthroughthickandthin,inspiteofdoubt,discouragement,andridicule,untilatlastsuccesscrownedhisefforts。Inallthelitigationwhichhasresultedfromthewide-spreadinfringementsoftheEdisonpatents,Mr。Lowreyhaseverbornetheburdenandheatoftheday,andperhapsinnootherfieldhashesopersonallydistinguishedhimselfasinthesuccessfuladvocacyoftheclaimsofEdisontotheinventionoftheincandescentlampandeverything“hereuntopertaining。“

  ThiswasthemanofwhomEdisonhadnecessarilytomakeaconfidantandadviser,andwhosuppliedotherthingsbesidesthelegaldirectionandfinancialalliance,byhisknowledgeoftheworldandofaffairs。

  ThereweremanyvitalthingstobedoneintheexploitationofthesystemthatEdisonsimplycouldnotandwouldnotdo;butinLowrey\'ssavoirfaire,readywitandhumor,chivalryofdevotion,gracefuleloquence,andadmirableequipoiseofjudgmentwereallthequalitiesthattheoccasiondemandedandthatmettheexigencies。

  WeareindebtedtoMr。InsullforagraphicsketchofEdisonatthisperiod,andoftheconditionsunderwhichworkwasdoneandprogresswasmade:“IdonotthinkIhadanyunderstandingwithEdisonwhenIfirstwentwithhimastomyduties。Ididwhateverhetoldme,andlookedafterallkindsofaffairs,frombuyinghisclothestofinancinghisbusiness。

  “ThefirstfewmonthsIwaswithEdisonhespentmostofthetimeintheofficeat65FifthAvenue。

  Thentherewasagreatdealoftroublewiththelifeofthelampsthere,andhedisappearedfromtheofficeandspenthistimelargelyatMenloPark。Atanothertimetherewasagreatdealoftroublewithsomeofthedetailsofconstructionofthedynamos,andEdisonspentalotoftimeatGoerckStreet,whichhadbeenrapidlyequippedwiththeideaofturningoutbi-polardynamo-electricmachines,direct-connectedtotheengine,thefirstofwhichwenttoParisandLondon,whilethenextwereinstalledintheoldPearlStreetstationoftheEdisonElectricIlluminatingCompanyofNewYork,justsouthofFultonStreet,onthewestsideofthestreet。

  Edisondevotedagreatdealofhistimetotheengineeringworkinconnectionwiththelayingoutofthefirstincandescentelectric-lightingsysteminNewYork。Apparentlyatthattime——betweentheendof1881andspringof1882——themostseriousworkwasthemanufactureandinstallationofundergroundconductorsinthisterritory。TheseconductorsweremanufacturedbytheElectricTubeCompany,whichEdisoncontrolledinashopat65

  WashingtonStreet,runbyJohnKruesi。Half-roundcopperconductorswereused,keptinplacerelativelytoeachotherandinthetube,firstofallbyaheavypieceofcardboard,andlateronbyarope;andthenputinatwenty-footironpipe;andacombinationofasphaltumandlinseedoilwasforcedintothepipefortheinsulation。Irememberasacoincidencethatthebuildingwasonlytwentyfeetwide。Theselengthsofconductorsweretwentyfeetsixincheslong,asthehalf-roundcoppersextendedthreeinchesbeyondthedrag-endsofthelengthsofpipe;andinoneoftheoperationsweusedtotakethelengthoftubingoutofthewindowinordertoturnitaround。IwaselectedsecretaryoftheElectricTubeCompany,andwasexpectedtolookafteritsfinance;anditwasinthispositionthatmylongintimacywithJohnKruesistarted。“

  Atthisjuncturealargepartofthecorrespondencereferredverynaturallytoelectriclighting,embodyingrequestsforallkindsofinformation,catalogues,prices,terms,etc。;andalltheseletterswereturnedovertothelightingcompanybyEdisonforattention。

  Thecompanywassoonswampedwithpropositionsforsaleofterritorialrightsandwithothernegotiations,andsomeofthesewereaccompaniedbytheofferofverylargesumsofmoney。Itwasthebeginningoftheelectric-lightfurorwhichsoonrosetosensationalheights。Hadthecompanyacceptedthecashoffersfromvariouslocalities,itcouldhavegatheredseveralmillionsofdollarsatonceintoitstreasury;butthiswasnotatallinaccordwithMr。Edison\'sidea,whichwastoprovebyactualexperiencethecommercialvalueofthesystem,andthentolicensecentral-

  stationcompaniesinlargecitiesandtowns,theparentcompanytakingapercentageoftheircapitalforthelicenseundertheEdisonpatents,andcontractingalsoforthesupplyofapparatus,lamps,etc。Thislefttheremainderofthecountryopenforthecashsaleofplantswhereverrequested。Hiscounselsprevailed,andthewisdomofthepolicyadoptedwasseenintheswiftestablishmentofEdisoncompaniesincentresofpopulationbothgreatandsmall,whosebusinesshaseverbeenaconstantandgrowingsourceofincomefortheparentmanufacturinginterests。

  FromfirsttolastEdisonhasbeenanexponentandadvocateofthecentral-stationideaofdistributionnowsofamiliartothepublicmind,butstillveryfarfrombeingcarriedouttoitslogicalconclusion。Inthisinstance,demandsforisolatedplantsforlightingfactories,mills,mines,hotels,etc。,begantopourin,andsomethinghadtobedonewiththem。Thiswasaclassofplantwhichtheinquirersdesiredtopurchaseoutrightandoperatethemselves,usuallybecauseofremotenessfromanypossiblesourceofgeneralsupplyofcurrent。IthadnotbeenEdison\'sintentiontocatertothisclassofcustomeruntilhisbroadcentral-stationplanhadbeenworkedout,andhehasalwaysdiscouragedtheisolatedplantwithinthelimitsofurbancircuits;butthisdemandwassoinsistentitcouldnotbedenied,anditwasdeemeddesirabletocomplywithitatonce,especiallyasitwasseenthatthesteadycallforsuppliesandrenewalswouldbenefitthenewEdisonmanufacturingplants。Afteraveryshorttrial,itwasfoundnecessarytocreateaseparateorganizationforthisbranchoftheindustry,leavingtheEdisonElectricLightCompanytocontinueundertheoriginalplanofoperationasaparent,patent-holdingandlicensingcompany。AccordinglyanewanddistinctcorporationwasformedcalledtheEdisonCompanyforIsolatedLighting,towhichwasissuedaspeciallicensetosellandoperateplantsofaself-containedcharacter。Asamatteroffactsuchworkbeganinadvanceofalmosteveryotherkind。Asmallplantusingthepaper-carbonfilamentlampswasfurnishedbyEdisonattheearnestsolicitationofMr。HenryVillardforthesteamshipColumbia,in1879,anditisamusingtonotethatMr。Uptoncarriedthelampshimselftotheship,verytenderlyandjealously,likefresheggs,inamarket-gardenbasket。Theinstallationwasmostsuccessful。AnotherpioneerplantwasthatequippedandstartedinJanuary,1881,forHinds&Ketcham,aNewYorkfirmoflithographersandcolorprinters,whohadpreviouslybeenabletoworkonlybyday,owingtodifficultiesincolor-

  “Itisthebestsubstitutefordaylightwehaveeverknown,andalmostascheap。“

  Mr。Edisonhimselfdescribesvariousinstancesinwhichthedemandforisolatedplantshadtobemet:

  ItshouldbeborneinmindthatfromtheoutsetEdisonhaddetermineduponinstallingundergroundconductorsastheonlypermanentandsatisfactorymethodforthedistributionofcurrentfromcentralstationsincities;andthatatMenloParkhelaidoutandoperatedsuchasystemwithaboutfourhundredandtwenty-fivelamps。Theundergroundsystemtherewaslimitedtotheimmediatevicinityofthelaboratoryandwassomewhatcrude,aswellasmuchlesscomplicatedthanwouldbethenetworkofovereightythousandlinealfeet,whichhecalculatedtoberequiredfortheundergroundcircuitsinthefirstdistrictofNewYorkCity。AtMenloParknoeffortwasmadeforpermanency;noprovisionwasneededinregardtooccasionalopeningsofthestreetforvariouspurposes;nonewcustomersweretobeconnectedfromtimetotimetothemains,andnorepairswerewithincontemplation。InNewYorkthequestionofpermanencywasofparamountimportance,andtheothercontingenciesweresuretoariseaswellasconditionsmoreeasytoimaginethantoforestall。

  Theseproblemswereallattackedinaresolute,thoroughgoingmanner,andonebyonesolvedbytheinventionofnewandunprecedenteddevicesthatwereadequateforthepurposesofthetime,andwhichareembodiedinapparatusofslightmodificationinuseuptothepresentday。

  Justwhatallthismeansitishardforthepresentgenerationtoimagine。NewYorkandalltheothergreatcitiesin1882,andforsomeyearsthereafter,wereburdenedanddarkenedbyhideousmassesofoverheadwirescarriedonuglywoodenpolesalongallthemainthoroughfares。Oneafteranotherrivaltelegraphandtelephone,stockticker,burglar-alarm,andothercompanieshadstrungtheircircuitswithoutanysupervisionorrestriction;andthesewiresinallconditionsofsagordecayramifiedandcrisscrossedineverydirection,oftenhangingbrokenandloose-endedformonths,therebeingnoofficialcompulsiontoremoveanydeadwire。Noneofthesecircuitscarrieddangerouscurrents;buttheintroductionofthearclightbroughtanentirelynewmenaceintheuseofpressuresthatwereevenworsethanthebullyoftheWestwho“killsonsight,“becausethiskindredperilwasinvisible,andmightlurkanywhere。Newpoleswereputup,andthelightingcircuitsonthem,withbutaslightinsulationofcottonimpregnatedwithsome“weather-proof“compound,straggledalloverthecityexposedtowindandrainandaccidentalcontactwithotherwires,orwiththemetalofbuildings。

  Somanyfatalitiesoccurredthattheinsulatedwireused,called“underwriters,“becauseapprovedbytheinsurancebodies,becamejocularlyknownas“undertakers,“andeffortsweremadetoimproveitsprotectivequalities。Thencametheoverheadcircuitsfordistributingelectricalenergytomotorsforoperatingelevators,drivingmachinery,etc。,andthese,whileusingalower,saferpotential,wereproportionatelylarger。Therewerenowiresunderground。

  AremarkofEdison,familiartoallwhohaveworkedwithhim,whenitisreportedtohimthatsomethingnewgoesallrightandissatisfactoryfromallpointsofview,is:“Well,boys,nowlet\'sfindthebugs,“andthehuntforthephylloxerabeginswithfiendish,remorselesszest。Beforestartingtheplantforregularcommercialservice,hebeganpersonallyaseriesofpracticalexperimentsandteststoascertaininadvancewhatdifficultieswouldactuallyariseinpractice,sothathecouldprovideremediesorpreventives。Hehadseveralcotsplacedintheadjoiningbuilding,andheandafewofhismoststrenuousassistantsworkeddayandnight,leavingtheworkonlyforhurriedmealsandasnatchofsleep。Thesecrucialtests,aimingvirtuallytobreaktheplantdownifpossiblewithinpredeterminedconditions,lastedseveralweeks,andwhilemostvaluableintheinformationtheyafforded,didnothinderanything,formeantimecustomers\'premisesthroughoutthedistrictwerebeingwiredandsuppliedwithlampsandmeters。

  OnMonday,September4,1882,at3o\'clock,P。M。,Edisonrealizedtheconsummationofhisbroadandoriginalscheme。ThePearlStreetstationwasofficiallystartedbyadmittingsteamtotheengineofoneofthe“Jumbos,“currentwasgenerated,turnedintothenetworkofundergroundconductors,andwastransformedintolightbytheincandescentlampsthathadthusfarbeeninstalled。Thisdateandeventmayproperlyberegardedashistorical,fortheymarkthepracticalbeginningofanewart,whichintheinterveningyearshasgrownprodigiously,andisstillincreasingbyleapsandbounds。
