I puta ia i te Whare Wananga o Columbia me te tohu paetahi i te tau 1949 me te tohu paetahi i te tau 1950, i roto i te pāngarau, ka uru atu ki IBM i te tau 1950. I roto i ana tau tuatahi e toru, i mahi ia i runga i te Selective Sequence Electronic Calculator (SSEC); Ko tana kaupapa nui tuatahi ko te tuhi i tetahi papatono hei tatau i nga tuunga o te Marama. I te tau 1953 i whakawhanakehia e Backus te reo Speedcoding, te reo taumata-teitei tuatahi i hangaia mo te rorohiko IBM, hei awhina i te whanaketanga raupaparorohiko mo te rorohiko IBM 701. He tino uaua te papatono i tenei wa, ana i te tau 1954 i whakakao a Backus i tetahi roopu ki te tautuhi me te whakawhanake i a Fortran mo te rorohiko IBM 704. Ko Fortran te reo papatono taumata-teitei tuatahi i whakamahia whānuitia.  Pātai: He aha ōna tohu kura?
