We deter- mined that each succeedingyear, one ormore present orformer scientistswith the Agricultural Research Service couldbe selected, subject to the followingcriteria: The selectee made a majorimpact on agriculturalresearch, eitherby the solutionofa significantagriculturalproblem throughresearch or byprovidingoutstandingleadership that significantly advanced agriculturalresearch. The selectee is a personwhose accomplishments are stillrecognizedby the agriculturalresearchcommunity. The selectee's characterandrecord ofachievement are worthyof emulationbyyoungeragricultural scientists. The selectee's achievements mustbe orhavebeen nationallyand/or internationallyrecognizedbypeers in the scientificcommunity. Todaywe honorthree outstandingscientistsbyinductingtheminto the Science Hall ofFame. Aplaque citingthe achievements ofeachwill be onpermanent displayinthe ARS NationalVisitor Center at the Beltsville Agricultural Research Center. 2000 Science Hall of Fame ) Virginia H. Holsinger ResearchLeader (Retired) DairyProducts ResearchUnit Wyndmoor, Pennsylvania Forresearch leadingto increased useofmilkproductsand forhumanitarian efforts in developingnutritiousformulations forinternationalfooddonation programs. irginia H. Holsingerisrenowned forherworkwith dairyproducts, especiallywheyand wheybeverages, but includingmanyotherproducts derived frommilk. Herworkonformulatedfoods foremergencyuse and food donationhas enrichedthe health ofneedypeople worldwide. Holsinger'sworkonwheyincludedcreatingawhey-soy drinkmix that serves inplace ofnonfat drymilkininternational food donation programs. Anotherproject developed alow-fatmozzarella now used in school-lunchpizza to meet the national 30-percent calories from fat nutritional goal. Holsingerhas alsobeeninvolved in development ofa product consistingofbutteroil encapsulatedin flouror sugar that does notrequire refrigeration. Hermostwidelyknownworkis development ofthe enzyme treat- mentthatmakes milkdigestiblebylactose-intolerantindividuals. This treatmentmakes milkavailable to millions whowere unable to drinkit without severe discomfort. This advance has opened up a large market formilkand milkproducts. InhermostrecentworkwithARS, Holsingerled development ofa corn-soyblendthat delivers the fullnutritionalneeds ofhungrypeople andis easilypreparedwithout cooking. This productwillbe usedin emergencies such as refugee camps and disaster centers aroundthe world. USDAhas recognizedHolsingerwith itsDistinguished Scientist of theYear, TechnologyTransfer, Superior Service, andDistinguished Service Awards. Manygroups outside government, includingthe American Chemical Society, the Institute ofFoodTechnologists, the NationalResearch Council, and the InternationalDairyFoods Associa- tion, have also recognized herachievements. 2000 Science Hall of Fame Marvin E. Jensen National Program Leader (Retired) WaterManagement Research Beltsville, Maryland Foradvancements in irrigation schedulingusingcomputer models toestimatesoil-waterbalanceandforadvancements in evapotranspiration theory. arvin E.Jensen developedthe first practical models of soil-waterbalance needed to improve irrigation schedul- ingusingcomputers. Hisworkincreased the efficiency ofuse ofwaterand energy, resultingin savings for farmers andconsumers. Byfactoringtogetherweather, soils, and crops, a water-balance equationcan showa crop's need forwaterthroughout the growing season. Backin the days ofslide rules and hand-cranked adding machines,Jensen and his associates produced one ofthe first practical evapotranspiration equations for studyingwaterusebycrops. As computersbecame more available,Jensen developed more detailed and more accurate formulations thatexploited the capabilitiesofthese electronictools. Jensen'sworkspawned modem scientificirrigation scheduling. Precise schedulingofirrigation applications produces savings in water and energy, which increase production and profits, as wellas provid- ingenvironmentalbenefits. The flourishingindustry ofirrigation scheduling, engineeringevaluation, andcrop consultingdeveloped out ofJensen's pioneeringwork. Jensen'sinternationalworkin Sri Lanka, Egypt, Romania, and elsewhere has advanced irrigation management around theworld, and he served as President ofthe International Commission on Irrigation andDrainage. Since retiringfromUSDAin 1987,Jensen has continued to serve the U.S. andworld agriculturalcommunity. Jensen hasreceivedmanyhonors. He delivered the MorrisonMemo- rialLecture in 1990. Heisanhonorarymemberofthe American SocietyofCivil Engineers, hasbeen elected to theNational Academy ofEngineering, andisa Fellowofthe AmericanSocietyofAgricultural Engineers. He has receivedawards fromASCE, ASAE, and the Irriga- tion Association.
