Ernest Orlando Lawrence (8. augusta 1901 - 27. augusta 1958) bio je pionirski američki nuklearni naučnik i dobitnik Nobelove nagrade za fiziku 1939. za svoj izum ciklotrona. Poznat je po svom radu na razdvajanju izotopa uranijuma za projekat Manhattan, kao i po osnivanju Nacionalne laboratorije Lawrence Berkeley i Nacionalne laboratorije Lawrence Livermore .
Diplomirani student Univerziteta Južne Dakote i Univerziteta Minnesota, Lawrence je doktorirao fiziku na Yaleu 1925. Godine 1928. zaposlen je kao vanredni profesor fizike na Kalifornijskom univerzitetu u Berkeleyu, postavši dvije godine kasnije najmlađi redovni profesor. Lawrenca je jedne večeri u biblioteci zaintrigirao dijagram akceleratora koji proizvodi čestice visoke energije. Razmišljao je kako se to može učiniti kompaktnim i došao na ideju za kružnu ubrzavajuću komoru između polova elektromagneta. Rezultat je bio prvi ciklotron.

Pored Nobelove nagrade, Lawrence je dobio Elliott Cresson medalju i Hughes medalju 1937. Comstock nagradu za fiziku 1938. godine, Duddell medalju i nagrade u 1940. Holley medalja u 1942. godine, medalju za zasluge 1946. godine, Nagradu William Procter 1951., Faradayevu medalju 1952., [1] i nagradu Enrico Fermi od Komisije za atomsku energiju 1957. [2] Postao je oficir Legije časti 1948., [1] i bio je prvi dobitnik Nagrade Sylvanus Thayer od strane Vojne akademije SAD -a 1958. [2]
Samo 23 dana nakon njegove smrti, regenti Kalifornijskog univerziteta izglasali su preimenovanje dva univerzitetska nuklearna istraživačka mjesta u Lawrence: Nacionalna laboratorija Lawrence Livermore i Nacionalna laboratorija Lawrence Berkeley . [3] Nagrada Ernest Orlando Lawrence ustanovljena je u njegovo sjećanje 1959. [4] Hemijski element broj 103, otkriven u Nacionalnoj laboratoriji Lawrence Berkeley 1961. godine, nazvan je po njemu Lorensij. [5] Godine 1968. njemu u čast osnovan je javni naučno -obrazovni centar Lawrence Hall of Science. [1] Njegovi radovi se nalaze u Bancroft biblioteci na Kalifornijskom univerzitetu u Berkeleyju. [6]
