Itwasattendedbymanyandincludedremembrancesbyseveralwhoknewhim.He isandwillbegreatlymissed.
RupwasborninKiel,Germanyin1943. HecompletedhisPh.D.intheoreticalnuclearphysicsin1973attheUniversityof
BonnundertheguidanceofKonradBleuler. Hecontinuedhisworkonnuclearforcesasa postdocatBonn,intheInstituteforTheoreticalNuclearPhysicsfrom1973-1975,and atSUNY-StonyBrookfrom1976-1977.He returnedtoBonnasaResearchAssociate from1978to1983andthenheldvisiting scientistpositionsatTRIUMFinBritish Columbia(1983-1985)andLAMPFatthe LosAlamoslabinNewMexico(1986-1988). WhileatLAMPF,RupwasalsoanAdjunct AssociateProfessorofPhysicsatUCLA.He wasthenhiredbytheUniversityofIdaho in1988asanAssociateProfessorandpromotedtoFullProfessorin1991,servingas ActingChairfrom2003to2006.Following hisdeath,Rupwasgiventhehonorarytitle ofDistinguishedProfessorEmeritus.
Inhisresearch,Rupdidground-breaking workonthenatureandmodelingofthe strongnuclearforcebetweenprotonsand neutrons.HebeganwithhisPh.D.dissertationandsubsequentpostdoctoralworkon sophisticatedmeson-exchangemodelsthat culminatedinthepopularBonnpotential. Whenquantumchromodynamics(QCD) appearedasthefundamentaltheoryofthe stronginteractions,makingthenuclearforce aresidualeffectoftheunderlyingquarkgluoninteractions,Rupbecameakeyplayer intheimplementationofStevenWeinberg’s ideasforaneffectiveinteractioninvolving mesonsandnucleons,constructedtosatisfy thesymmetriesoflow-energyQCD.Thisled towhatisnowknownaschiralperturbation theory.Inbetween,Rupmadeimportant contributionstothestudyofnuclearmattertoincludemesondegreesoffreedomand relativisticeffects.

Theopticalgapatroomtemperaturemeasuredapproximately4.85eV,whichistypicalfornanocrystallinethinfilms.Analysis oftheelectron-phononinteractionshowed theinvolvementofalow-energyphononat around30meV.Defects,includingdisorderedgraphiteform,Sp2networkincor-
