This should be easy, but I just can't figure it out. It must be someone who won in Los Angeles and had already won before it. Only Seb Coe and Ulrike Meyfart (sp.?) occur to me as such persons (Daley Thompson had to hurdle). But Coe got just one silver, didn't he? And Meyfart also certainly did not get two silvers. Hence, I am simply missing something/somebody or my logic fails in some point I cannot understand.
