Editing Jack Ryan (character) (section)

===Civilian career===
While managing clients' portfolios, Ryan began to invest his own money, banking on a tip he had received from an uncle about the workers' takeover of the [[Chicago and North Western Railway]], making about $6 million off his $100,000 initial investment. He did so well that one of Merrill Lynch's senior vice presidents, Joe Mueller, came to Baltimore to have dinner with him, with the objective of inviting him to the firm's [[New York City]] headquarters near [[Wall Street]]. Also present is Mueller's daughter Caroline, nicknamed Cathy, then a senior medical student at The [[Johns Hopkins University School of Medicine]]. They immediately fall in love and get engaged.

One night, while having dinner with his fiancée, Ryan throws out his back. Cathy takes him directly to Dr. Stanley Rabinowitz, a professor of [[neurosurgery]] at the famed [[Johns Hopkins Hospital]] in Baltimore, to be evaluated. Rabinowitz later operates on Ryan's back and cures his chronic pain in relatively short order. (In a later novel, the surgeon is credited as Sam Rosen, a doctor introduced in ''[[Without Remorse]]''.) Ryan subsequently persuades the government to terminate his disability checks. Cathy later becomes an [[Ophthalmology|ophthalmic]] surgeon at the [[Wilmer Eye Institute]] of the [[Johns Hopkins University School of Medicine]] and a professor of surgery at Johns Hopkins.

After creating a net worth of $8 million, Ryan left the firm after four years and enrolled at [[Georgetown University]] in [[Washington, D.C.]] for six [[doctorate|doctoral]] courses in history. He does a brief stint at the [[Center for Strategic and International Studies]], then accepts a position at the U.S. Naval Academy as a civilian professor of history. In addition, he has also written books on naval history: ''Options and Decisions'', ''Doomed Eagles'', and ''Fighting Sailor'', a biography of World War II Admiral [[William Halsey Jr.|William "Bull" Halsey]], in which he justifies Halsey's actions during the [[Battle of Leyte Gulf]].
