The USA made things very clear in the heats with a time of 40.6 (40.61
on electric timing), which equalled Germany’s world record, though
the USA’s time was unratified because of their performance the next
day. Germany, winners of the other heat in 41.2 (41.22), were drawn in
lane 4 in the final, with the USA in lane 1. Kiesel gave the USA a fine
start, gaining 2m on veteran Körnig, and the USA steadily drew away
to win by 9m in 40.0 to destroy the world record. Had the USA decided
to use Metcalfe, Tolan and Simpson, their three fastest men, the time
might have been nearer 39.5.
