An saiyang mga magurang iyo sinda George asin Lillian Little, mga imigranteng Jewish. An saiyang ama taga - Rusya alagad nagdakula sa Liverpool, Inglaterra. An saiyang ina namundag sa Nueva York asin an saiyang mga magurang mga imigranteng Ruso-Polinesyo. Sa edad na 17, si George nagbalyo sa US asin nagin matrayumpong paragibo nin gubing. Inapresyar nia an mga oportunidad na magkaigwa nin negosyo alagad gusto nia na an saiyang mga aking babae magkonsentrar sa edukasyon. Igwa siyang tolong aki, sinda Kenneth P. Birman, Debora Birman Shlider, asin Carl David Birman. An saiyang huring agom, si Joseph Birman, sarong pisiko asin pangenot na parasuportar sa mga diretso nin tao para sa mga sientista.

Pakatapos nin haiskul, si Birman naglaog sa Swarthmore College, sarong institusyon nin pagkolehiyo sa Swarthmore, Pennsylvania, asin mayor sa matematika. Alagad, habo niya mag erok sa mga dormitoryo kaya nagbalyo siya sa Barnard College, solong kolehiyo na para sana sa mga kababaihan igdi sa Columbia University, na nagtutugot na mag-istar sa harong.
