rdfs:comment	سام روبن (بالإنجليزية: Sam Ruben)‏ هو عالم كيمياء حيوية وكيميائي أمريكي، ولد في 5 نوفمبر 1913 في سان فرانسيسكو في الولايات المتحدة، وتوفي في 28 سبتمبر 1943. (ar) Samuel Ruben (5. listopadu 1913 San Francisco – 28. září 1943), narozený jako Charles Rubenstein, byl americký biochemik. Společně s Martinem Kamenem objevil radioaktivní izotop uhlíku 14C. Při bombardování hmoty částicemi z cyklotronu vznikaly radioaktivní izotopy prvků jako 14C. Jeho použití v biochemii pomohlo objasnit průběh mnoha reakcí probíhajících v živých organismech. Společně rovněž poskytli důkaz, že kyslík vznikající při fotosyntéze nepochází z oxidu uhličitého, ale z vody. Zemřel na následky otravy fosgenem, který unikl při nehodě v laboratoři.

(en) Sam Ruben, nato Charles Rubenstein (San Francisco, 5 novembre 1913 – 28 settembre 1943), è stato un biochimico statunitense, membro del Progetto Manhattan. Insieme a Martin Kamen ha scoperto il radiocarbonio il 27 febbraio 1940 presso l'università Lawrence Berkeley National Laboratory di Berkeley, che usarono in una serie di esperimenti sulle piante nei quali scoprirono che la trasformazione della CO2 in zuccheri poteva avvenire anche al buio. Morì in un incidente di laboratorio dove lavorava allo studio del gas tossco fosgene del quale fu intossicato.

(pt) Samuel Ruben (nascut amb el nom de Charles Rubenstein, 5 de novembre de 1913 – 28 de setembre de 1943), era fill de Herschel i Frieda Penn Rubenstein – el nom va ser oficialment escurçat a Ruben el 1930. Quan la seva família es va traslladar a Berkeley, va ser un jugador amb èxit de bàsquet a la Berkeley High School. Es va doctorar en química el 1938. (ca) Sam Ruben (* 5. November 1913 in San Francisco als Charles Rubenstein; † 28. September 1943) war ein US-amerikanischer Chemiker. Er ist bekannt für die Synthetisierung des langlebigen Kohlenstoffisotops C14 mit Martin Kamen (1940). 1949 wurde C14 von Willard Frank Libby für die Radiokarbondatierung benutzt. Er war seit 1935 verheiratet und hatte drei Kinder. Sein Sohn George war Professor am Dartmouth College. Er sollte nicht mit dem US-amerikanischen Erfinder Samuel Ruben (1900–1988), Gründer von Duracell, verwechselt werden. (de)
