Holley Virgil A. Johnson George F. Sprague The Agricultural Research Service Fame Science Hall of The ARS Science Hall ofFame was inaugurated in 1986. We determined that each succeeding year, one ormore present orformer scientists with the Agricultural Research Service could be selected, subject to the following criteria: • The selectee’s research must have contributed significantly to the solution of amajor agricultural problem and reflect credit on the Agricultural Research Service. • The selectee is recognized nationally and internationally by his orher peers in the scientific community. • The selectee’s character and record ofachievement is worthy of emulation by younger agricultural scientists. • The selectee must be eitherretired oreligible to retire and must continue to be professionally active. Today we honor several outstanding scientists by inducting them into the Science Hall ofFame. A plaque citing the achievements ofeach will be on permanent display in the ARS National Visitor Center at the Beltsville Agricultural Research Center. R. Dean Plowman Administrator June 11, 1991 1991 John H. Weinberger Research Horticulturist (retired) Horticultural Crops Research Laboratory Fresno, California For outstanding lifelong contributions in development offruit varieties andfruit breeding technology. JohnH. Weinbergerdeveloped andreleased 37 fruitvarieties (22peach, 6 nectar- ine, 3 plum, 1 Prunusrootstock, 1 apricot, 1 table grape, 1 raisin grape, and 2 graperootstocks) during his41 years withARS andits predecessors. Beforehis retirementfromARS in 1973, he alsomade the originalcrosses and selection of several otherimportantvarieties thathave sincebeenreleased. Flame Seedless, the table grapevarietyhereleasedin 1973, is now the second mostimportantseedless grapeproducedinthe United States. Since its 1973 introduction, 2—3,765 acres h—avebeenplantedin Californiaalone. Anotherofhis developments FriarPlum is the majorJapanese-typeplum grownin California. Itis thefirstplumto surpass productionofLutherBurbank’s SantaRosaplum. Thepeach andnectarinevarieties developedby Dr. Weinbergerare extensively grownnotonlyin California, butaroundthe world. Nemaguardrootstock, which isresistanttonematodes, is nowthe majorpeachrootstock usedinthe southern SanJoaquinValley, the mainpeach-producingregion in California. Nemaguardis also amajorrootstockforplums, nectarines, apricots, andalmonds. In the cour—se ofbreedingnew fruitvarieties, Dr. Weinbergeralso developedbetter techniques suchas arapidpropagationmethodforgrowing graftedgrapevines. The grape industryhas adoptedthis improvedmethod andnow grafts mostofthe plantsinthe greenhouseinsteadofthefield. Dr. Weinbergeris aFellow ofthe American SocietyforHorticultural Science and arecipientofthe WilderAwardfromthe AmericanPomological Society. He receivedtheUSDA SuperiorService Awardin 1964 andits Distinguished Service Awardin 1973. ThoughretiredfromARS, heremains active as aconsultantand breederforacommercialfirm inFresno.
