You could say they disappeared in the early 50s, ended up somewhere around 30 years ago. The JSA itself retired, the kids grew up and formed Infinity Inc around 10 years ago (around the same time that the New Teen Titans were operating), the JSA reformed around five years ago which is when Jesse Quick debuted.
