Dr John Patrick  Jack  Ryan, Sr. , KCVO (Hon.) , Ph.D. is a fictional character created by Tom Clancy who appears in many of his novels and their respective film adaptations. Jack Ryan was born in Baltimore in 1950 and grew up there.
Even though the new Amazon adaptation, âTom Clancyâs Jack Ryan,â uses the authorâs name in the title, itâs more of a symbolic gesture than denoting strict adherence to the past. After all, the eight-episode series isnât based on any of Clancyâs books. But it is inspired by the franchiseâs impressive past.
