Not Stein, maybe Carlo Senoner, Italian who won the slalom at the Portillo World Championships.
The guy is neither Stein nor Senoner.
His name is Franz Vogler, born 1948, German architect.
Back in 1966 he was a good student of architecture and a promising young racer but not good enough to be sent to the distant Portillo destination.
His fans from the city of Oberstdorf collected (maybe what we now term as crowdfounding, maybe some wealthy sponsor) the money needed and somehow persuaded the German Federation to send him there at no costs for the federation budget. (While they nominated both the notoriously unsuccessful racer Heidi Mittermaier and her younger sister Rosi, only 16 during the Championships...)
The tall guy, third in the DH race, was celebrated as a future potential champion.
He was probably the last WCS male „amateur“ medalist ever. (Old Avery Brundage should have celebrated him!) The other at Portillo was probably „your“ Penny McCoy in her teenage years sponsored by her family...
Voglers great ski career never happened. He raced on without a podium placement till 1972. After the Sapporo Olympics he finally won a WC DH, then quit and had a „serious“ life as an architect.
Btw, Senoner was on Dynamics VR 17 at Sapporo. He was a young marvel at 16 but the older the less racing success he had. Injured after 1964 he was almost an outsider in Chile and definitely not a medal contender. He had his lucky moments there, he promptly quit and has been living on the Portillo fame since.
Btw2, the best SL skier there was a forgotten Swede Bengt-Eric Grahn. He won the first leg by 1.7 seconds, kept his lead in the 2nd but unfortunatelyy crashed not far from the finish.
(Another SL star was Billy Kidd, in January 1966 considered the best racer even by European journalists, but he unfortunatelty broke his leg in DH training at Portillo and could not participate.)
Anyone wonder Mr. Grahn living in a small place Tärnaby with 700 souls became a hero for local skiing kids including Ingemar Stenmark?
I understand „a Swede“ is active here (hi!), he might add more.
