Jack Larson is best known to Superman fans as Jimmy Olsen on
the George Reeves Superman television show of the
1950's. He's also showed up in the Superboy tv series,
and he played older Jimmy Olsen on Lois and Clark on an
episode where Jimmy gets stricken with old age. Not a lot of
photos of Jack Larson himself floating around, but he is a
very important part of the Superman television history.
