  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。

  Atthisjuncturealargepartofthecorrespondencereferredverynaturallytoelectriclighting,embodyingrequestsforallkindsofinformation,catalogues,prices,terms,etc。;andalltheseletterswereturnedovertothelightingcompanybyEdisonforattention。
  Thecompanywassoonswampedwithpropositionsforsaleofterritorialrightsandwithothernegotiations,andsomeofthesewereaccompaniedbytheofferofverylargesumsofmoney。Itwasthebeginningoftheelectric-lightfurorwhichsoonrosetosensationalheights。Hadthecompanyacceptedthecashoffersfromvariouslocalities,itcouldhavegatheredseveralmillionsofdollarsatonceintoitstreasury;butthiswasnotatallinaccordwithMr。Edison'sidea,whichwastoprovebyactualexperiencethecommercialvalueofthesystem,andthentolicensecentral-

  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-

  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。
